#612 Added instance_track_index and instance_fx_index variables to dynamic expressions (allows us cycling through tracks/FX while pinning them as instance track/FX)
#613 Improved usability by making trigger-like targets controllable with encoders (by default, each encoder increment/decrement will trigger the target)
Improved virtual source label in mapping row
#614 Fixed cut-off MIDI device names

#403 Added support for OSC type tags Int and Long
#358 Added new context menu action "Named listed mappings after source"
#358 Improved keyboard source significantly (save/load, more reliable key catching, catching of modifier-only key presses, keystroke normalization for better cross-platform experience, portability warnings)
#549 Improved selectors "All by name" and "All selected" by allowing combinatorial explosion (you can now easily target many FX, FX parameters and sends on many tracks with just one target ... powerful, use with caution!)
#551 Improved OSC by using one socket for sending and receiving OSC messages (makes "respond to sender" possible, used for example by Behringer XR mixers)
#550 Improved user interface on macOS by taking up less vertical screen space (and a tiny bit less horizontal one, too)

#332 Added limited support for offline rendering (works now with REAPER >= v6.52+dev0323, limited to controlling FX parameters on the same track)
#518 Added source "Timer" for repeated triggering of arbitrary targets (you can find it in source category "REAPER", can for example be used to repeatedly send a particular OSC message, which is a precondition to support Behringer X32 OSC)
#358 Added work-in-progress "Keyboard" source (NO SAVE of source settings yet!)
#501 Added option in context menu to log not just real but also incoming/outgoing virtual control elements and values (very useful for debugging mappings)
#539 Added invocation mode "Absolute (7-bit)" to target "Project: Invoke REAPER action" (for controlling actions that don't correctly interpret 14-bit values, e.g. "SWS/SM: Live Config #1 - Apply config (MIDI/OSC only)")
#504 Added plug'n'play for MIDI devices, also on Windows (automatically resends all feedback shortly after MIDI device plugged in without further user interaction)
#544 Added John's presets for Behringer MOTÖR and FCB1010
#336 Added clip engine to be used by upcoming Playtime 2 (this is by far the biggest addition but you can't use it yet :P ... more about this in the next pre-release)
#526 Improved target "MIDI: Send message" by lifting all previous restrictions when using destination "FX output" (Yes, you can now play your VSTs via OSC!)
#540 Improved precision for entering and displaying percentages and dB to 4 fractional digits (e.g. useful for values in value sequences)
#530 Improved error reporting by including the name of the channel in case a channel ran full
#336 Improved ReaLearn plug-in topology by removing output pins (since ReaLearn doesn't output any audio streams)

#448 Added support for textual feedback (usable with OSC String sources and MIDI hardware displays: Mackie, SiniCon)
#393 Added comprehensive built-in support for import and export of the all-new ReaLearn Script = Build ReaLearn presets/mappings in Lua! (Attention: Small adjustments to the ReaLearn Script API data structure are to be expected during the 2.11 and 2.12 release cycles!)

#449 Added new target "ReaLearn: Enable/disable instances" for flexibly enabling/disabling complete ReaLearn instances during a performance (great for paging)
#438 Added target "ReaLearn: Enable/disable mappings" for flexibly enabling/disabling mappings during a performance (can be used as a more straightforward alternative to conditional activation, especially when it comes to bank/zone switching scenarios)
#325 Added target "ReaLearn: Navigate within group" for cycling through mappings in a mapping group (for intuitively defining sequences e.g. for implementing pages, zones etc.; support sequences spanning completely different targets!)
#376 Added possibility to control using system-exclusive MIDI messages (by using the existing very flexible "Raw MIDI" source, which only worked for feedback direction so far - now supports learning, value extraction using patterns and logging of incoming messages)

#470 Added variable 'selected_track_indexes' array variable to dynamic expressions (making it possible to e.g. control 1st selected track with fader one, 2nd selected track with fader two, etc.)
#393 Added new "Track" target which is well-suited as neutral target for getting textual feedback for track properties (but will get more interesting functionality at a later stage, see #228)
#62 Added JSON schema of the API data structure (in order to potentially support writing ReaLearn presets/mappings in other languages as well, especially typed ones, e.g. TypeScript)
#131 Added header panel context menu action 'Make sources of all main mappings virtual'
#178 Added optional track dropdown to "Project: Invoke REAPER action" target (The target makes sure that this track is selected before executing the action. This makes it possible to combine ReaLearn's flexible track selection capabilities with the plethora of REAPER actions that work on the currently selected track.)
#280 Added target "Send: Automation mode"
#280 Added target "Send: Mono/stereo"

#393 Improved "Mackie Control" and "iCON Platform M+" controller presets (added support for LCD and timecode display, track peak meter and any-solo button, fixed encoder acceleration behavior, many small improvements, easier to maintain because generated from ReaLearn Script)
#393 Improved performance, code complexity and serialization independence of preset dirty checking by using a much simpler method than before (before: comparison of JSON; now: setting dirty flag whenever e.g. a mapping changed)
#393 Improved virtual control element naming by increasing maximum length from 16 to 32
#393 Improved wording by renaming "Tuning" to "Glue"
#394 Improved target "ReaLearn: Load mapping snapshot" by allowing to restrict snapshot loading to mappings with certain tags and activity state
#432 Improved auto-load preset functionality to work better with shell plug-ins, e.g. Waves (now by default uses plug-in name instead of file name to distinguish between the single plug-in types; in order for this to take effect, you need to remove each problematic link and reestablish it or edit the link and fill out the FX ID name yourself)
#435 Improved projection feedback by sending feedback initially, not just on value changes or on manual request via REAPER action
#436 Improved target value entry by providing buttons for trigger- or switch-like targets
#452 Improved "Toggle buttons" mode to support exclusive toggle button use cases (if target min is equal to target max, it now toggles between that specific value and zero)
#477 Improved <Dynamic> track selector by allowing it to address the master track (if the expression returns value -1)
#481 Improved dynamic expressions by letting 'track_selected_index' evaluate to the special variable 'none' if no track is selected, allowing users to choose a suitable fallback in that case
#481 Improved dynamic expressions by making 'selected_track_index' and 'this_track_index' support master track (value -1)
#481 Improved dynamic expressions by making compartment parameters available as array variable 'p' (now you can write p[0] instead of p1])
#481 Improved dynamic expressions by making target inactive if the expression fails (e.g. if an undefined variable is used)
Improved Raw MIDI source to control and learn incoming short (non-sys-ex) messages as well
Improved documentation of what's special about "MIDI: Send message" target and what limitations it has
Improved performance of "MIDI: Send message" target when sending to feedback output by avoiding deallocation in audio thread
Improved usability by disabling certain UI elements depending on the selected OSC argument type

#62 Fixed feedback update for secondary target properties (e.g. track name)
#62 Fixed feedback update for property-based feedback style (e.g. color based on property 'target.track.color')

#441 Fixed bug in 2.10 that caused disabling and reenabling ReaLearn FX to stop control

2.10.0 2021-09-06

#350 Added option "Poll for feedback" (enabled by default) to the few targets for which the REAPER API doesn't provide any value change notification or not in all cases (essentially makes automatic feedback work for all targets, also fixes the issue that switching presets from within a FX UI doesn't resend FX parameter feedback)
#348 Added header context menu options to log incoming/outgoing MIDI/OSC messages (great for debugging)
#363 Added track selector "All by name" which resolves to many tracks instead of only the first one if the name contains wildcards and multiple tracks match
Added mapping row context menu option to log debug info for a single mapping
#330 Added new tuning setting "Group interaction" for controlling multiple mappings within the same group at once, in multiple interesting ways
#330 Added source category "None", to be used with mappings that are not supposed to be controlled directly but just via "Group interaction"
#391 Added support for target value sequences (including ranges, customizable step sizes etc., even supports true relative control!)
#411 Added target unit button for switching between 1. native target unit and 2. percentages (chosen unit will be used whenever entering/displaying target values or step sizes, saved per mapping)
#424 Added visual mapping (source) match indicator, both in mapping row and mapping panel
#423 Added "All by name" FX selector (lets you use wildcards now to resolve to multiple FX, quite useful with the "FX: Enable/disable" target for simulating controller pages)
#378 Added possibility to use ReaLearn as global MIDI filter (by making "Let through" checkboxes available even when choosing real hardware MIDI input device, needs REAPER >= v6.36!)
#401 Added source "MIDI device changes" in new source category "REAPER" (for reacting to MIDI device plug/unplug events)
#386 Added variable selected_track_index for use in dynamic track expression
#394 Added a very work-in-progress version of the new "ReaLearn: Load mapping snapshot" target (only restores the initial target values of all instance mappings at the moment but will become much more powerful in future)

#370 Added mapping option "Show in projection" (enabled by default)
#379 Added controller preset and instructions for "Arturia KeyLab MkII" (thanks to dissofiddle)

#433 Improved error handling by logging only the first warning message in a sequence of equal warning messages
Improved UI semantics by renaming target category "REAPER" to "Real"
#427 Improved usability by disallowing addressing FX "By ID" if the track is not sticky (that is, not <This> or addressed "By ID") ... allowing was nonsensical and confusing
#425 Improved FX parameter "By position" selector so you can enter the position in a text field (parameter dropdown is now available as selector "By ID")
#426 Improved consistency of target label in mapping row (e.g. don't show resolved track/FX/parameter name if selector is not "By ID")
#421 Improved usability of target dropdowns by making it possible to change the track/FX selectors while keeping entered values (e.g. having the name always prefilled when switching from "By ID" to "By name")
#417 Improved user guide (better table of contents, better quick start, migrated to AsciiDoc)
#414 Improved projection by sending projection feedback even if feedback disabled for controller mapping
#413 Improved fire mode "After timeout" by making it work in combination with "Press only" button filter (you can now press a button and no matter how long you press it, it will fire after the specified timeout)
#395 Improved versatility by guaranteeing mappings within one compartment to be processed in the order of definition (exception: ReaLearn parameters)
#387 Improved "MIDI/OSC: Send message" targets by making it work with "Toggle buttons" mode and relative encoders
#350 Improved performance for targets that poll for feedback (e.g. "Track: Peak") by processing and sending feedback only if value actually changed
#362 Improved reliability by migrating to stable Rust (just an internal change)
#350 Fixed "nervous motor faders" issue by not sending batch feedback anymore when starting to play or seeking
#366 Fixed predefined "MIDI: Send" target patterns (7-bit patterns reported to be 14-bit-capable)
#415 Fixed takeover modes misbehavior in presence of restricted source/target value range
#396 Fixed bug that let "Send feedback after control" not send feedback after control in some corner cases
#416 Fixed "Last touched" target: Make it work correctly if other FX parameter is currently automated (also improves FX parameter learning in presence of parameter automation)
#434 Fixed error "REAPER string should be UTF-8 encoded" with certain FX parameter names
#390 Fixed bug that caused "The pipe is being closed" error on some systems when choosing "MIDI: Send message" target
#406 Fixed non-reliable dynamic selectors for send, FX and FX parameters (was only working reliably for tracks before)
#369 Fixed MiniLab mkII controller preset: Projection feedback for pads works now
#332 Fixed confusing logic that caused the preset save button to not be greyed out after making mappings project-independent
#405 Fixed lag when sending MIDI messages to FX output (both when letting incoming messages through and when sending them via "MIDI: Send message" target)
#388 Fixed bug that caused ReaLearn send targets to forget the kind of send

2.10.0-pre.10 2021-09-02

#32 Added "Fire after timeout, keep firing" mode for button presses (turbo mode!)
#223 Added "Seek" target (including feedback on beat changes or in high resolution!)
#235 Added support for showing current target values in projection view (= "Projection feedback", needs latest version of the ReaLearn Companion app to work)
#12 Added takeover modes "Parallel" and "Catch up" (renamed existing takeover modes to "Pick up" and "Long time no see")

#269 Added new source character "Toggle button" as a workaround for hardware buttons that can't be configured to act as momentary buttons (should usually be avoided; behavior is that it always sends 1 even when 0 is received)
#270 Added new fire modes "Single press" and "Double press" (can now distinguish between single press, double press and long press)
#220 Added possibility to use preset name in addition to plug-in name when creating preset links for the "Auto-load preset" feature (allows you to load a different ReaLearn main preset when the preset of the focused FX changes)

#4 Added new track selector "All selected" to make track targets (NOT FX and send targets) work on all selected tracks
#322 Added right-click menu action "Move listed mappings to group"
#231 Improved compartment presets by making them save/restore the customized compartment parameter names as well
Improved feedback for controller mappings with virtual targets (enabling it again will restore feedback, that was previously not the case)
#267 Improved understandability by renaming "Program" to "Bank" in conditional activation

#301 Improved usability by displaying mapping group name on right when showing mappings in all groups
Improved "Duplicate" by getting rid of the annoying "Copy of ..." prefix
#233 Improved usability by hiding mapping tuning options which are not relevant at all in the current context
#300 Improved user friendliness by raising step size max to 5% and speed max to 5x (in order to make it more obvious to new users that ReaLearn supports encoder acceleration and velocity-sensitive buttons)
#307 Improved usability by removing the UI difference between numbered and named virtual control elements (internally numbers are still treated a bit differently, but on the surface it's the same now)
Improved usability by explicitly indicating when target is currently inactive
Improved naming by renaming "Rotate" to "Wrap" and "Move instance to upper floor" to "Make instance superior"
#154 Improved Midi Fighter Twister user guide entry by explaining how to use encoder acceleration and by linking to ReaLearn-compatible MFT Color Designer web app

#271 Improved usability by renaming and reordering targets, also introduced additional target hint label
#227 Improved "Move to upper floor" feature by detecting more reliably when instance not active anymore and unloading presets more reliably when FX window closed

2.8.0-pre7 2021-03-30

#264 Added new targets "FX open" (for opening/closing a specific FX via button) and "FX navigate" (for navigating with prev/next buttons or encoders within FX chain)
#261 Added new targets "Track automation mode" and "Automation mode override"
#190 Added new target "Track show/hide"
#262 Added new transport actions "Pause" and "Stop" to "Transport target" (for more fine-grained feedback)
#260 Added checkboxes "Scroll TCP" and "Scroll mixer" to targets "Selected track" and "Track selection"
#215 Added checkboxes "Set loop points" and "Set time selection" to target "Go to region"
#259 Added "Paste mappings (replace all in group)" to header context menu
#226 Added "FX-to-preset links" to header context menu for better management and for making it possible to map multiple plug-ins to the same preset
#226 Added possibility to use plug-in file name wildcards (* and ?) when linking an FX to a preset (another way to map multiple plug-ins to the same preset)
#269 Added new source character "Toggle button" as a workaround for hardware buttons that can't be configured to act as momentary buttons (should usually be avoided; behavior is that it always sends 1 even when 0 is received)
#267 Improved understandability by renaming "Program" to "Bank" in conditional activation
#263 Fixed feedback issues due to numerical inaccuracies (especially useful for radio-button-like feedback from discrete target values)
#265 Fixed "FX chain chunk not found" error when on monitoring FX and "Auto-load preset" on
#249 Fixed sometimes missing feedback on target activation changes (e.g. when "Track must be selected" is used)

2.8.0-pre6 2021-03-25

#227 Added ability for "Auto-load preset: Depending on focused FX" instances to cancel other instances that share the same device (with this, you can easily let your controller control the currently focused FX but fall back to your usual controls when it's closed)
#249 Added ability that multiple instances work hand in hand when it comes to feedback (As long as 2 instances don't actively feedback to more than one control element at once, everything will be fine and should work just as with conditional activation within 1 instance.)
Improved UI in minor ways
#255 Improved usability by respecting activation state of controller mappings with virtual targets when learning a main mapping source
#231 Improved usability by showing only short parameter name in conditional activation parameter dropdowns
#231 Fixed annoying bug that made group changes have an effect only ever in one of the compartments

2.8.0-pre5 2021-03-23

#231 Added mapping group feature to controller compartment (was previously available in main compartment only)
#231 Added conditional activation to controller compartment (was previously available in main compartment only)
#231 Added 100 more freely assignable VST parameters to ReaLearn (now we have 200 parameters in total divided into the already existing 100 main compartment parameters and 100 new controller compartment parameters)
#209 Added possibility to customize parameter names via header panel context menu
#231 Improved compartment presets by making them save/restore the customized compartment parameter names as well
#235 Improved companion app value projection feedback by updating the feedback in more cases if "Feedback output" is "None"
Improved feedback for controller mappings with virtual targets (enabling it again will restore feedback, that was previously not the case)
Fixed UI for controller mappings with virtual targets (previously showed advanced fire modes although not supported for virtual targets)

2.8.0-pre4 2021-03-22

#186 Added FX selector <This> for targeting the own ReaLearn instance (good for using conditional activation and <Dynamic> in reusable presets)
#121 Added copy/paste of mappings or even just sources/modes/targets (also across compartments and instances)
#157 Added copy/paste of the complete filtered mapping list (e.g. to copy/paste whole compartments, groups or search results)
#244 Added possibility to use names for virtual control elements instead of numbers
#246 Added quick start section at the top of the user guide
#236 Added FAQ section to the user guide
#247 Fixed possible "unwrap" error with certain mapping tuning settings, e.g. jump and step size
Fixed possible "borrow" error when using FX parameter target with own ReaLearn instance

2.8.0-pre3 2021-03-18

#235 Added support for showing current target values in projection view (= "Projection feedback", needs a prerelease version of the ReaLearn Companion app to work)
#12 Added takeover modes "Parallel" and "Catch up" (renamed existing takeover modes to "Pick up" and "Long time no see")
#237 Fixed idle CPU usage when having OSC feedback enabled for at least one OSC device (was quite high)
#234 Fixed channel "Full" error when invoking lots of actions in a small amount of time
Fixed bug that was causing ReaLearn to forget the FX in FX targets (introduced in 2.8.0-pre1)

2.8.0-pre2 2021-03-13

#166 Added "Fire after timeout" mode for button presses
#32 Added "Fire after timeout, keep firing" mode for button presses (turbo mode!)
#223 Added "Seek" target (including feedback on beat changes or in high resolution!)
#225 Fixed bug in "Go to marger/region" target that caused markers/regions to be triggered even on button release

2.8.0-pre1 2021-03-11

#212 Added new FX instance selector "Dynamic"
#213 Added new FX parameter selectors "Dynamic" and "By name"
#214 Added new send/receive/output selectors "Dynamic", "By ID" (source/destination track ID) and "By name"
#72 Added option to use track receives (change of perspective) and hardware output sends instead of track sends only
#217 Added possibility to use wildcards (* and ?) in all name selectors to match only parts of names
#218 Fixed error when controlling "Last touched" target after the last touched target is gone (e.g. after track deleted)
#208 Fixed too early rotation when using "Incremental buttons" in combination with "Rotate"

2.7.1 2021-03-09

#160 Added new track type "Dynamic" (allows to calculate a track number depending on ReaLearn's internal parameter values)
#160 Improved target track picker GUI by making it easier to create ReaLearn presets that are going to be used across different projects (e.g. "By name" now lets you enter a string as one would expect)
#160 Improved performance by trying to not send too much unnecessary feedback when mapping or mapping target activation states change
#210 Improved handling of REAPER's "Audio device closed" state (in ReaLearn < 2.5.0 being in that state for a long time could have led to slow memory exhaustion, in ReaLearn < 2.7.0 it would eventually lead to an error message "Full" instead - which is already better, and in 2.7.0 it's handled as it probably should)
#207 Fixed error message complaining about negative positions when using count-in and sometimes when playing from the very project start (introduced in 2.6.0)
Improved usability by not intentionally generating a backtrace when pressing "Log debug info" (that caused confusion)
Improved usability by reducing likelihood for audio dropouts by avoiding allocation in real-time thread when using very many mappings (probably premature optimization)
Fixed another possible error message when closing a project while ReaLearn is open

2.6.0 2021-03-07

#5 Added experimental and feedback-enabled (!) "Go to marker/region" target with smooth seek for regions
#198 Added very flexible feedback-only "Raw MIDI" source in order to support feedback on controllers whose LEDs etc. can only be controlled via system-exclusive MIDI messages (e.g. Arturia MiniLab mkII)
Added user guide entry and controller preset for Arturia MiniLab mkII (pad feedback now works thanks to ReaLearn's new sys-ex support!)
Added user guide entry for OSC/PILOT
#197 Improved usability of min/max text fields on Windows and macOS by changing the value (and correcting the other value) not before leaving the field instead of immediately (the behavior before that was downright annoying as you can see here)
#113 Improved editing of advanced mapping settings by opening a dedicated small edit window with instant error checking (instead of just opening the system text editor, which sometimes doesn't work)
#201 Fixed possible "Full" error message when having projects with very many tracks
#199 Fixed possible error message with "Master tempo" target when mapping panel open

2.5.0 2021-03-03

#113 Added foundation for setting advanced aspects of mappings via textual configuration (accessible via new mapping panel button "Advanced settings")
#113 Added foundation for using very device-specific features by allowing to send a bunch of raw MIDI data (including SysEx!) on mapping activation/deactivation (see user guide section "Advanced settings" for details)
#196 Added option "Can deal with OSC bundles" to OSC device popup menu which can be unticked in order to achieve compatibility with devices not supporting them (e.g. Behringer mixers)
Added user guide entries and controller presets for PreSonus FaderPort 8 and FaderPort Classic
#182 Improved reliability by avoiding memory exhaustion in the presence of potential programming errors (internally use bounded channels instead of unbounded one)
Improved user guide and projection instructions by explaining how to open a context menu
#193 Fixed possible folder overflow with the "Exclusive: Within folder" setting introduced in the previous release
#185 Fixed non-occurring mapping row target label updates when track list changes
#194 Fixed sometimes non-arriving MIDI feedback on project load

2.4.0 2021-02-26

#156 Added "Exclusive" dropdown to all "track property on/off"-style targets (arm, selection, mute, solo, fx all enable, automation touch state) which even allows "Exclusive within folder" behavior (my personal favorite)
#147 Added "Automation touch state" target in order to support "Touch" automation mode for volume, pan and width envelopes (e.g. with touch-sensitive faders or push encoders)
#47 Added option "Behavior" for "Track solo" target, start using the routing-friendly "Solo in front" behavior by default
#176 Added REAPER action "ReaLearn: Send feedback for all instances" (useful mainly for debugging purposes because ReaLearn usually sends feedback automatically)
#162 Improved "Track solo" target by making it work with "Options → Solo in front"
#176 Improved usability by clearing feedback (switch off lights or turn down motorized faders) when closing ReaLearn instance or REAPER project
#171 Improved "Track mute" target by making it work reliably also on master track and by making feedback from automation work
#167 Improved usability by disabling learning of "Track selection" target if REAPER preference "Mouse click on volume/pan faders and track buttons changes track selection" enabled (in order to avoid false positives, preference change respected after REAPER restart)
#170 Improved usability by making "Master tempo" target uneligible as "Last touched" target and for learning in general (there were too many false positives and it could get annoying at times, just select the target manually in the dropdown to use it)
#165 Improved usability by letting the user confirm before globally removing an OSC device
#181 Improved usability by not firing immediately when changing the encoder turning direction while using a negative "Speed" setting (that was annoying and could result in sudden unwanted parameter changes)
#177 Improved usability by not annoying user with error messages when controlling just because they use some setting that doesn't make sense (such as controlling relative targets with absolute messages)
Improved usability by clearing feedback of the previous source if a mapping source is changed
#168 Fixed non-working automation writing for "Track width" target when controlled via relative encoder
#172 Fixed often missing initial feedback for virtual controller mappings (LEDs were sometimes not updated before interacting with the project, e.g. by pressing play)
#177 Fixed possible "assertion failed: 0.0 <= normalized_value || normalized_value.is_nan()" error with volume targets
#179 Fixed recent bug that caused "Track selection" target to be learned with wrong track (the previously selected one instead of the newly selected)
#180 Fixed recent bug that caused wrong "Selected track" target feedback

2.3.2 2021-02-23

Improved usability by vastly increasing OSC feedback performance ... much smoother now (MIDI feedback has been reworked as well and should be more snappy and accurate, too)

2.3.1 2021-02-22

Fixed non-visible "Link current preset to FX ..." context menu entry

2.3.0 2021-02-21

#153 Added experimental OSC support (supports control, feedback, learning, virtual controls, presets, basically everything that's possible with MIDI sources, doesn't yet support textual feedback - e.g. control element labels)

2.2.0 2021-02-16

#147 Added experimental "Load FX snapshot" target
#130 Added experimental "Last touched" target
#149 Added section about ReaLearn Companion app section to user guide
#143 Fixed "Prevent echo feedback" by increasing echo detection threshold duration
#146 Fixed "Called Option::unwrap() on a None value`" error (could occur with large track/FX chunks)

2.1.0 2021-02-13

#142 Added "Track width" target (for stereo pan mode)
#141 Added "Track send mute" target (feedback not possible at the moment due to REAPER limitations)
#140 Added "X" button next to search field for clearing it
#137 Improved user guide by adding "Auto-load preset" tutorial
#139 Fixed "Couldn't parse VST tag line" error when using "Auto-load preset" (could happen if you used FX renaming)
#136 Fixed colors when using custom Windows theme that has rather dark background color
#138 Fixed colors when using macOS dark mode
#143 Fixed possible "BorrowError" when saving presets
#144 Fixed possible "Project not available" error when closing project while mapping panel still open

2.0.1 2021-02-10

#29 Added controller mapping feature (possibility to define controller-specific mappings, virtual sources and virtual targets)
#29 Added a bunch of controller presets
#7 Added possibility to refer to a track via its name or position (as an alternative to the default of using its unique and stable ID) ← That's called track anchors, a powerful addition, if you ask me!
#40 Added controller projection feature (by using the new ReaLearn Companion app)
Added indication of scroll position and number of mappings
#33 Added possibility to let unmatched FX input MIDI events through even when using hardware input (the checkbox isn't greyed out anymore)
#74 Added support for main presets (analogously to controller presets)
#68 Added batch-learning of multiple mappings (new button "Learn many")
#67 Added FX anchors (analogously to track anchors)
#66 Added new target FX option "<Focused>" (analogously to track "<Selected>")
#77 Added preset auto-loading depending on focused FX (!)
#85 Added possibility to assign mappings to different groups and set activation condition and control/feedback enable state for each group
#73 Added limited MIDI feedback support for MIDI CC actions (requires REAPER >= 6.20)
#79 Added possibility again to enter values > 100x in Speed text field (useful e.g. when using relative encoders with some NI plug-ins that report continuous parameters with step sizes that are very low)
#80 Added performance measuring of ReaLearn control surface methods (including exposing metrics in Prometheus format)
#104 Added possibility to use preset "Reset to factory default" to clear all settings, groups and mappings (without changing the session ID)
#115 Added user guide sections "Tested controllers" and "Tutorials"
#123 Added experimental new option 'Make absolute' in order to convert relative to absolute values (lets you use EEL control transformation with encoders)
#125 Added powerful REAPER actions for learning and finding mappings without opening ReaLearn
#87 Improved source character guessing (yields best results when turning clockwise!)
#86 Improved learning of transport buttons (now prefers ReaLearn's built-in transport target over the corresponding REAPER actions)
#88 Improved usability by automatically clearing filters and search expression when adding a mapping (to make sure it's shown)
#75 Improved preset usability by asking user whether to automatically convert project-anchored targets to project-independent ones
#70 Improved usability by scrolling to newly added/duplicated mapping if necessary
Improved usability by rethinking the mapping mode concept (The mapping window section is now called "Tuning" instead of "Mode" because a mapping can now cope with both relative and absolute source values, no matter the mode! It just depends on whatever value type the source emits - relative or absolute values. From now on, the "Mode" just describes how to interpret incoming absolute values. This is a "mostly" backward-compatible change since it changes only behavior of mappings that didn't have an effect anyway till now because source value type and mode didn't match.)
#38 Improved usability by indicating mappings that are "off" by greying them out
#37 Improved resource usage by greatly reducing project file size, undo entry size and preset size
Improve error logging (makes it easier to map debug symbols, on Windows at least)
#56 Improved usability by making most confirmation and alert dialogs modal with respect to the ReaLearn window itself, not REAPER
#64 Improved accessibility by fixing tab order, default buttons and initial focus (affects mapping panel only because REAPER doesn't seem to support tab control in the actual main FX window)
#43 Improved consistency by letting program numbers start at 0 (just a visual change)
#60 Improved versatility by increasing number of conditional-activation parameters to 100
#61 Improved quality assurance by adding a few integration tests (new developer action)
#57 Improved usability by making online and offline user guide accessible via context menu (plus some other links)
Improved usability by also stopping source filter learning when clearing the source filter
#69 Improved usability disabling all control while learning a target (no more undesired target learning by moving an already assigned control, at least within one ReaLearn instance)
#99 Improved usability by including source character in mapping row source label (makes it easier to spot character guessing issues)
#96 Improved (N)RPN scanning to support popular controllers (such as Behringer BCR2000), prefer value-MSB-first now
#101 Improved user interface by making mapping rows less grey and adding some horizontal rules
#114 Improved usability by making "Absolute" the default invocation mode for actions, was "Trigger" before (this change could break some action mappings done with previous 1.12.0 prereleases)
#106 Improved "Length" sliders to work for "Incremental buttons" mode, too
#119 Improved usability by always sorting groups alphabetically
#116 Improved usage of ReaLearn as monitoring FX by making parameter feedback and learning work (usually, REAPER extensions don't get notified of anything happening on the monitoring FX chain, but at least for ReaLearn parameter changes I managed to create a workaround ... which is good news especially for global conditional activation use cases)
Improved user guide (related to keyboard input, monitoring FX and limitations of monitoring FX)
#117 Improved safety by warning whenever loading something made in a newer ReaLearn version than the current one (version number gets part of the preset data, that also paves the way for preset migration)
#124 Improved usability by preferring position anchors over ID anchors when learning from a ReaLearn instance that is on the monitoring FX chain
#122 Improved wording related to encoders, renamed internal named parameter for setting state to 'set-state'
Improved usability by making ID now really the new default FX anchor, not 'ID or position'
Improved awareness by changing the prime EEL control transformation example into an actually very useful one: a curve
#127 Improved usability by indicating if MIDI input or output device disabled in REAPER preferences
#126 Improved behavior by disabling control (not just feedback) for disabled ReaLearn FX instances (before this, it still kept controlling when a device was selected as 'MIDI control input')
#134 Improved projection QR code detection rate by greatly simplifying it for now (doesn't carry certificate content anymore, which was only useful when using web-based companion app from mobile device, which is an edge case, especially considering that an iOS app is on the way)
#135 Improved usability by automatically switch off source/target filter learning when doing certain UI interactions
Fixed nonsense learning of virtual sources in controller mappings compartment (that was really bad for batch learning control elements)
Fixed missing mapping lanel UI update when learning other parameter of same FX
#132 Fixed 'Solo' target learning (was always resulting in master track)
#128 Fixed bug that caused ReaLearn-monitoring-FX controlled targets to become sticky when switching between project tabs (not updating correctly)
Fixed error message when pressing space bar in an empty ReaLearn instance
#103 Fixed possible "Raw pointer..." error when using track selection targets
#105 Fixed possible "couldn't get FX param value..." error when using FX parameter target
#110 Fixed action invocation mode "trigger", which sometimes wouldn't fire
#111 Fixed misleading labels in mapping panel
#111 Fixed feedback when reverse enabled and target range non-symmetric
#112 Fixed bug with broken plug-ins that report parameter as discrete but with a nonsensical step size of zero
#97 Fixed broken arrow symbols on Windows 7 (display rectangles instead of arrows)
#98 Fixed "Couldn't get preset count" error
#95 Fixed (N)RPN learning and consumption check
#94 Fixed wrong info that feedback not working for (N)RPN (it works!)
#93 Fixed "Track send pan" target (was confused with "Track send volume")
#71 Fixed bug that caused overscrolling when clicking on "Find in mapping list" button
#36 Fixed inconsistent feedback processing order (changes behavior of existing feedback transformation formulas if used in combination with source or target interval restrictions, so they might need some adjustment!)
#30 Fixed error when choosing non-MSB controller for 14-bit CC sources (now silently converted to MSB controller)
#58 Fixed "Find in mapping list" not switching mapping compartment
#39 Fixed bug that caused initial parameter values to be sometimes ignored in conditional activation
#50 Fixed scrolling issues when mapping list filtered
#46 Fixed error message when trying to pick action
#35 Fixed "is not a valid unit value" error (happened when reading volume values above the fader limit set in REAPER preferences)
#54 Fixed "negative MIDI frame offset" error (negative offsets are interpreted as zero now)
#55 Fixed "Message: assertion failed: Bpm::is_valid(value)" error (could happen when using controllers that send MIDI clock)
#53 Fixed "Message: -1 is not a valid value" error (caused by unexpected FX parameter change value)
#31 Fixed Windows 7 character issues in dropdown menus
#23 Fixed error message if track could not be found
#59 Fixed REAPER crash when using automation on ReaLearn conditional-activation parameters
#78 Fixed error when encountering MIDI device name with incorrectly encoded special characters
#82 Fixed error when encountering invalid MIDI messages (they are now ignored)
#84 Fixed bug that caused ReaLearn to stop working when project paused and ReaLearn track not armed
#92 Fixed auto correction for "Send feedback only if track armed"
#100 Fixed bug that could cause target value to get stuck if step size too small when it could be avoided
Fixed "BorrowMut" error and potential race conditions when "Allow live FX multiprocessing" enabled
#83 Fixed segmentation fault on Linux when loading ReaLearn after plug-in scan
#117 Fixed wrong reverse behavior in 'Normal' mode when target value range is non-symmetric (old presets will keep their wrong behavior in order to not break existing projects)

1.12.0-pre21 2021-02-08

Added controller presets and user guide entries for X-Touch Compact, Mackie Control, iCON Platform M+ and MIDI Fighter Twister Bank 2
#134 Improved projection QR code detection rate by greatly simplifying it for now (doesn't carry certificate content anymore, which was only useful when using web-based companion app from mobile device, which is an edge case, especially considering that an iOS app is on the way)

When loading with pre9, check if there are any sources that unwillingly contains <Any> as channel or number, manually change it to 0 and save the project/preset!)
#84 Fixed bug that caused ReaLearn to stop working when project paused and ReaLearn track not armed

#29 Improved usability by prompting user for confirmation before switching from no preset to some preset if there are mappings defined already
Improved usability by also stopping source filter learning when clearing the source filter
#69 Improved usability disabling all control while learning a target (no more undesired target learning by moving an already assigned control, at least within one ReaLearn instance)
#71 Fixed bug that caused overscrolling when clicking on "Find in mapping list" button
#36 Fixed inconsistent feedback processing order (changes behavior of existing feedback transformation formulas if used in combination with source or target interval restrictions, so they might need some adjustment!)

1.12.0-pre7 2020-12-14

#33 Added possibility to let unmatched FX input MIDI events through even when using hardware input (the checkbox isn't greyed out anymore)
#64 Improved accessibility by fixing tab order, default buttons and initial focus (affects mapping panel only because REAPER doesn't seem to support tab control in the actual main FX window)
#43 Improved consistency by letting program numbers start at 0 (just a visual change)
#60 Improved versatility by increasing number of conditional-activation parameters to 100
#61 Improved quality assurance by adding a few integration tests (new developer action)
#57 Improved usability by making online and offline user guide accessible via context menu (plus some other links)
#30 Fixed error when choosing non-MSB controller for 14-bit CC sources (now silently converted to MSB controller)
#58 Fixed "Find in mapping list" not switching mapping compartment
#53 Fixed "Message: -1 is not a valid value" in a better way (translating negative values to zero instead of ignoring them)
#59 Fixed REAPER crash when using automation on ReaLearn conditional-activation parameters
#7 Fixed UI inconsistency by hiding track anchor dropdown if not relevant

1.12.0-pre6 2020-12-08

#7 Added possibility to refer to a track via its name or position (as an alternative to the default of using its unique and stable ID) ← That's called track anchors, a powerful addition, if you ask me!
#40 Improved consistency by preventing the session ID to become non-unique as result of actively changing it via context menu
#29 Improved usability by making virtual target the default for new controller mappings
#56 Improved usability by making most confirmation and alert dialogs modal with respect to the ReaLearn window itself, not REAPER
#31 Fixed Windows 7 character issues in dropdown menus
#23 Fixed error message if track could not be found

1.12.0-pre5 2020-12-07

Added Linux build again
#29 Added two controller presets, downloadable via ReaPack (in this context, controller preset directory has been changed to Data/helgoboss/realearn/controllers)
#40 Improved usability by printing possible solutions when projection server could not be started
#40 Improved stability and portability by migrating from web view to opening the projection setup page in the user's browser
#40 Improved QR code detection results by increasing QR code size
#35 Fixed "is not a valid unit value" error (happened when reading volume values above the fader limit set in REAPER preferences)
#54 Fixed "negative MIDI frame offset" error (negative offsets are interpreted as zero now)
#55 Fixed "Message: assertion failed: Bpm::is_valid(value)" error (could happen when using controllers that send MIDI clock)
#53 Fixed "Message: -1 is not a valid value" error (caused by unexpected FX parameter change value)
#40 Fixed header panel context menu on macOS
#40 Fixed crash on macOS when pressing projection button (by replacing web view with browser)
#40 Fixed not showing QR code on Windows 7, probably because of old IE version
Fixed failure when opening presets that don't yet contain activationType

1.12.0-pre4 2020-12-03

#29 Added controller mapping feature (possibility to define controller-specific mappings, virtual sources and virtual targets)
#40 Added controller projection feature (by using the new ReaLearn Companion app)
Added indication of scroll position and number of mappings
Improved usability by rethinking the mapping mode concept (The mapping window section is now called "Tuning" instead of "Mode" because a mapping can now cope with both relative and absolute source values, no matter the mode! It just depends on whatever value type the source emits - relative or absolute values. From now on, the "Mode" just describes how to interpret incoming absolute values. This is a "mostly" backward-compatible change since it changes only behavior of mappings that didn't have an effect anyway till now because source value type and mode didn't match.)
#38 Improved usability by indicating mappings that are "off" by greying them out
#37 Improved resource usage by greatly reducing project file size, undo entry size and preset size
Improve error logging (makes it easier to map debug symbols, on Windows at least)
#39 Fixed bug that caused initial parameter values to be sometimes ignored in conditional activation
#50 Fixed scrolling issues when mapping list filtered
#46 Fixed error message when trying to pick action

1.11.0 2020-09-16

#11 Added feature 'conditional activation' for (de)activating mappings based on parameter values
#8 Added transport target with proper feedback (play/pause, play/stop, record, repeat)
#20 Added option to send feedback after each control cycle
#27 Added possibility to further specify "Out of range" behavior (the new option "Min" is especially useful for mappings where a button sets a target to a specific constant value)
#26 Improved installation instructions and added controller tips to the documentation
#158 Improved usability by showing hierarchical folder structure in track dropdown
#19 Improved usability by asking user for confirmation before removing a mapping
#19 Improved usability by simplifying mapping window title
#28 Fixed strange and unreliable feedback if target min is equal to target max
#24 Fixed bug that caused "FX must have focus" to not work at all with floating windows and work incorrectly when in FX chain
Fixed action targets reporting wrong character, leading to wrong auto correction behavior

1.11.0-pre2 2020-09-01

#8 Added transport target with proper feedback (play/pause, play/stop, record, repeat)
#20 Added option to send feedback after each control cycle
#158 Improved usability by showing hierarchical folder structure in track dropdown
#19 Improved usability by asking user for confirmation before removing a mapping
#19 Improved usability by simplifying mapping window title
Fixed action targets reporting wrong character, leading to wrong auto correction behavior

1.11.0-pre1 2020-08-28

#11 Added feature 'conditional activation' for (de)activating mappings based on parameter values

1.10.0 2020-08-27

#193 Added Linux support
#152 Added target 'Selected track' for navigating within track list
#71 Added mapping name search
#179 Added support for non-latin characters (in mapping names and when showing track names)
#177 Added support for using ReaLearn as monitoring FX
#178 Added version and build information to UI
Added possibility to quickly check what a certain knob/fader/encoder/switch actually controls, without actually changing target parameters (implemented by simply making source filter run until pressing 'Stop' and by not filtering unknown sources)
Added feedback for target 'Track FX preset'
Added possibility for relative mode to throttle/slow-down relative increments (the 'step count' sliders are now called 'speed', negative values represent throttling)
Added possibility for absolute and toggle modes to distinguish between short/long button presses ('Length' slider allows you to define press durations on millisecond granularity - obviously works with momentary switches only)
#13 Added mapping option 'Prevent echo feedback' (good for motorized faders that don't like feedback while being moved)
Added target 'Track FX all enable' (without feedback)
#1 Added feedback transformation for relative and toggle mode, too (because feedback is always absolute)
#3 Added possibility to access current target value in control transformation (initial value of y)
Added feedback reset logic when source not in use anymore (e.g. sends 'zero' feedback value if mapping removed)
Added developer action for resolving backtraces that just contain addresses (also stripped debug symbols from Linux release artifact)
#181 Added option to send MIDI feedback to 'FX output' instead of directly to MIDI hardware device
Added button 'Log debug info' for printing some debug information on a terminal (not the REAPER console!)
Improved error handling: Some possible smaller errors/misbehaviors where totally ignored in previous versions and therefore might have gone unnoticed. In this version, ReaLearn will print a bug report if it detects such a smaller error, exactly like it already did before with more serious errors. (ReaLearn follows a fail-fast approach in order to detect errors early instead of letting them introduce subtle and hard-to-analyze bugs.)
#2 Improved toggle mode by letting Source Min/Max clamp feedback value just like in other modes
Improved 'Log debug info' by logging to REAPER console instead of terminal
Improved behavior when using 'Learn source filter': Also indicate if a source has been touched that is not used in any mapping (by showing an empty mapping list)
#42 Improved UI for action target (now uses REAPER's built-in action picker)
#182 Improved duplicate naming ('Copy of ...')
#156 Improved UI by immediately reflecting track name changes
#146 Improved UI by using actual arrow symbols (macOS and Windows only)
Improved UI by having better error window if clipboard import is wrong
Improved UI by instantly updating mapping name and all other values changed via text input field while typing
Improved feedback by keeping it more in sync with the mapping settings (e.g. also updates while changing target range)
Improved relative mode by giving the 'step size' / 'step count' (now 'speed') controls an overhaul
Improved usability by not letting target fields forget their values when switching type
Included more diagnostic information in error log messages (debug info such as line numbers)
Made a complete rewrite in Rust programming language
Published as open source (available on GitHub)
#8 Fixed logic error after learning target on master track
#9 Fixed crashes on logic errors while executing VST plug-in callbacks. Now it just reports an error message instead of aborting REAPER.
#208 Fixed non-working 'Track must be selected' target condition
Fixed non-moving slider when slider currently focused
#206 Fixed some FX parameter target bugs which caused ReaLearn to error on particular values
Fixed another possible 'ghost session' bug (ReaLearn sticking around although already unloaded)
Fixed non-working FX parameter selection
Fixed sometimes not working FX parameter learn
Fixed possible missing learn/feedback notification right after startup
Fixed possible error message when using -inf dB
Fixed bug that caused ReaLearn instance to stay around as a ghost even if already removed. That caused surprising issues e.g. complaints about a target parameter not being found which was not used at all.
#205 Fixed continuous MIDI feedback of automated FX parameter values, track send volume and track send pan. Now fires on real value changes only. It’s still possible that ReaLearn sends more feedback than necessary when having automation. This can happen if there are value changes but they are so small that they don’t have any effect on the feedback MIDI value (because MIDI feedback values have a very low resolution).)
Fixed some random error messages when using FX parameter target with parameters that report step sizes
#189 Fixed crashes when removing plug-ins
#197 Fixed bug that caused feedback and learn not working with master track

1.10.0-pre8 2020-08-19

#13 Added mapping option 'Prevent echo feedback' (good for motorized faders that don't like feedback while being moved)

Improved behavior when using 'Learn source filter': Also indicate if a source has been touched that is not used in any mapping (by showing an empty mapping list)
#208 Fixed non-working 'Track must be selected' target condition
Fixed non-moving slider when slider currently focused

1.10.0-pre5 2020-06-29

1.10.0-pre3 2020-06-25

Fixed some random error messages when using FX parameter target with parameters that report step sizes
Include more diagnostic information in error log messages (debug info such as line numbers)

1.10.0-pre2 2020-06-24

Made a complete rewrite in Rust programming language
Published as open source (available on GitHub)
#193 Added Linux support
#152 Added target 'Selected track' for navigating within track list
#71 Added mapping name search
#179 Added support for non-latin characters (in mapping names and when showing track names)

Improved feedback by keeping it more in sync with the mapping settings (e.g. also updates while changing target range)
Improved relative mode by giving the 'step size' / 'step count' (now 'speed') controls an overhaul
Improved usability by not letting target fields forget their values when switching type
#189 Fixed crashes when removing plug-ins
#197 Fixed bug that caused feedback and learn not working with master track

1.8.0-pre1 2018-12-08

#163 Improved resilience by introducing a fault barrier (whenever an error occurs, ReaLearn tries to prevent a hard crash and instead displays error information with instructions how to report it to the developer)
#169 Improved toggle mode by respecting target min/max while deciding whether to switch target parameter on or off
#168 Improved relative mode by making it support MIDI feedback as well (the feedback itself of course transmits absolute values, everything else wouldn't make sense)
#172 Improved usability and reduced complexity by removing the separate device dropdown from the MIDI clock sources and instead using the global MIDI input device (Migration instructions for people who have already used the experimental MIDI clock sources in projects: If your MIDI clock input device is different from the global MIDI input device, you need to use two ReaLearn instances now!)
#162 Improved usability by not letting source and mode fields forget their values when switching source/mode type
#175 Improved UI update behavior when using FX parameter target with track '<Selected>'
#161 Fixed possible crash when enabling/disabling take FX
#167 Fixed possible crash when using track selection target
#175 Fixed messed up mappings when dragging FX above another FX which is controlled by ReaLearn
#173 Fixed incorrect step size/count 'min' and 'max' naming
#174 Fixed potential weird behavior by preventing ReaLearn from learning a target which is in another project tab than ReaLearn itself
#174 Fixed track names in mapping window of ReaLearn instances in inactive project tabs
#170 Fixed crash when deleting a monitoring FX which is used in a ReaLearn target (please note that monitoring FX is not completely supported in ReaLearn because of limitations in the REAPER SDK, e.g. feedback is not possible)

1.7.1 2018-08-08

#159 Added possibility to use ReaLearn on master track
#160 Improved 'FX must have focus' by sending feedback when FX gets focus

1.7.0 2018-08-06

#134 Added possibility to select '<Any>' as source note, CC and channel
#157 Improved usability by always displaying track/FX/parameter positions and MIDI device IDs in labels and dropdowns
#150 Improved usability by ignoring FX reordering and removal whenever '<Selected>' is chosen for track targets. That just makes more sense. So there's not such a tight connection to the FX anymore in this case. It will use whatever FX is at the position and if there is none it won't do anything.
#139 Improved usability by automatically scrolling mixer when selecting track via 'Track selection' target
#149 Improved usability by also displaying disconnected MIDI devices in REAPER >= 5.94 (if you think there are so many now that it gets confusing, it's time to clean up in REAPER => Preferences => Audio => MIDI Devices by using the 'Forget device' operation ;)
#140 Improved processing by completely disabling feedback and control (even if coming from direct hardware device) whenever ReaLearn FX is disabled
#143 Improved processing by disabling 'MIDI thru' if MIDI control input comes directly from a hardware device (so ReaLearn will now only forward MIDI messages to its FX output if they come from its FX input)
#147 Improved processing by reliably detecting if FX change occurred on input FX chain or normal FX chain for REAPER >= 5.95pre1
#148 Improved performance in some cases by using new function in REAPER >= 5.95pre1 to look up the project for a given track
#155 Improved performance in some cases by never creating an undo point when arming/disarming ReaLearn track
#133 Improved usability by adding a remark to targets 'Track FX enable' and 'Track mute' that they don't provide feedback from automation changes (currently not possible, capability needs to be added on REAPER side)
#151 Fixed non-working relative mode for probably most JS FX, also fixed detection of discrete FX parameters
#142 Fixed crash when using a fader after having removed a ReaLearn instance with direct hardware device input
#144 Fixed OS X crash related to MIDI device API changes in REAPER 5.94 (also fixed in REAPER 5.941)
#145 Fixed confusing OS X MIDI device dropdown behavior if device is not known by explicitly displaying a temporary entry '<Unknown>' instead of just displaying the first entry in the dropdown

1.6.1 2018-07-06

#128 Added possibility to apply a track target to the currently selected track (via new track option '<Selected>'; also renamed '<Current>' to '<This>' to make more clear what is meant)
#129 Added possibility to receive MIDI directly from device (via 'MIDI control input' dropdown, good for example if you want to use the track input for something else such as recording audio)
#130 Improved mapping window size and layout so that things don't get cut off
#131 Improved usability by graying out 'Send feedback only if track armed' if ReaLearn is on input FX chain (because then feedback is always only sent if track armed)

1.6.0 2018-07-05

#122 Added 'Track FX preset' target for navigating between FX presets (no value feedback because REAPER's API doesn't notify extensions about preset changes)
#121 Added 'Track FX enable' target for enabling/disabling track FX
#123 Added possibility to change mapping name
#124 Added source min/max also to toggle mode (used for feedback only)
#125 Improved track arm, mute, select and solo target types by triggering them as soon source value > source min value (doesn't have to be source max value anymore)
#126 Improved mode reset and auto-detection for targets with discrete values by choosing sensitive default values for step sizes
#127 Fixed rotate option and made it more simple/predictable

1.5.3 2018-06-26

#119 Added playrate target
#120 Fixed track selection for track arm target
#118 Fixed non-working ReaLearn on 32-bit REAPER installations

1.5.2 2018-06-21

#115 Improved control performance (significant improvement, ReaLearn shouldn't cause any crackling anymore when doing fast fader movements)
#116 Improved feedback performance
#114 Improved performance on load and when reordering FX

1.5.1 2018-06-15

#109 Fixed showstopper crash related to orphan mappings
#108 Fixed potential crash when closing project or exiting REAPER
#112 Fixed crash and issues with current track functionality in some situations (e.g. when instantiating track templates containing both ReaLearn and Kontakt in a second project tab)
#111 Fixed 'Learn source for last touched target' action so it supports the recent new target types
#110 Fixed mute and solo targets so value changes also inform other control surfaces

1.5.0 2018-06-11

#67 Added possibility to export and import all ReaLearn settings to and from clipboard (e.g. useful for exchanging presets and doing batch modifications of ReaLearn settings via text editor)
#16 Added support for transforming incoming (control) and outgoing (feedback) values in absolute mode via mathematical functions (EEL is used, the same language which REAPER uses for JS effects - that let's you do all kind of interesting things, is more usable than putting a JS MIDI effect in front of ReaLearn and it gives you the complete target parameter precision because you deal with 64-bit floating point numbers instead of the usual 7-bit MIDI message precision; x is the incoming control value, y is the target value, both are numbers between 0 and 1; for example a control transformation 'y = 1 - x' creates a reverse effect)
#101 Added master tempo target (it was possible before to change REAPER tempo by using an action target but you didn't get feedback and BPM rounding)
#73 Added track selection target (you can also select a track exclusively)
#54 Added mute and solo track targets
#86 Added track send pan target
#100 Added 'MIDI clock transport' source (for receiving play/continue/stop messages directly from MIDI hardware inputs; they can be mapped to transport actions in REAPER in order to make REAPER a MIDI clock slave regarding transport control)
#100 Added very experimental 'MIDI clock tempo' source (if you map this to the new 'Master tempo' target, you can turn REAPER into a MIDI clock slave regarding project tempo; but don't expect too much, the resulting tempo is currently unstable; IMHO a much better method if you want REAPER tempo to reflect the tempo of e.g. Ableton Live, is to create a ReaLearn mapping with a 'CC value' source and a 'Master tempo' target with target min = 73 bpm and max = 200 bpm and to let Ableton Live send tempo feedback using the same CC and tempo range ... this combined with native REAPER SPP sync and you have instant tempo and song position changes; whereas MIDI clock tempo sync has an inherent delay due to its nature)
#77 Added track target option 'Track must be selected'
#26 Added absolute mode option 'Slowly approach if jump too big (scale mode)' (of course only has an effect if max jump is small enough)
#102 Added absolute mode option 'Min jump' to also let users specify a minimum parameter jump, not only a maximum one
#101 Added absolute mode option 'Round target value' for supported targets (currently only 'Master tempo', in order to round to integer BPM values)
#92 Added button to send MIDI feedback manually
#80 Added zip file downloads to website to be used for portable REAPER installations
#91 Added feedback option 'Send only if track armed' (enabled by default for new presets because it makes sense; if ReaLearn is on the input FX chain, feedback is never sent if the track is disarmed)
#97 Added source and target filtering to mapping list window in order to let users find existing mappings easier (e.g. to quickly check if a particular mapping is already there)
#72 Added buttons for moving mapping up or down
#106 Added 'Find in mapping list' button to edit mapping window
#107 Added checkboxes for enabling/disabling control/feedback also to edit mapping window
#88 Added mapping numbers for being able to better identify mappings (especially after duplicating a mapping)
#83 Improved Windows installer by making it more predictable and easier to use (user doesn't have to choose the VST directory anymore, ReaLearn will always be installed into a fixed dedicated VST directory, REAPER VST scanning path will be modified if necessary so the ReaLearn VstPlugins directory is the last one ... last one has highest priority, so old installed versions are just ignored)
#61 Improved usability by closing mapping dialog when pressing escape key
#84 Improved mapping list window performance if there are many mappings
#78 Improved preset reusability by discovering tracks by name if they are not found by their unique GUID (that way one and the same ReaLearn preset can be used in different projects as long as those projects have tracks with the same names)
#89 Improved scrolling behavior
#105 Improved usability by not closing mapping edit windows when closing ReaLearn mappings window (not needing to leave the mappings window open saves screen space)
#90 Improved usability by marking REAPER project as dirty when changing something within ReaLearn
#104 Improved usability by making it possible to enter step counts and step sizes of discrete target parameters directly instead of having to enter percentages (also removed the decrease/increase buttons because they are not really useful anymore after this change)
#103 Improved usability by making it possible to enter target values directly instead of having to enter percentages (only for supported targets, FX parameters for example don't support this)
#96 Improved control behavior by ignoring NOTE OFF messages sent by REAPER when pressing play (those messages make absolute sense for stopping VST instruments from sounding but they accidentally reset target parameters when using ReaLearn)
#82 Fixed buggy installer on Mac OS X
#81 Fixed problem that caused ReaLearn not to work in 32-bit REAPER installations on Mac OS X
#70 Fixed possible crash when learning target
#50 Fixed cropped window when using scaling on Windows (e.g. on HiDPI screens)
#76 Fixed bug in 'Auto-detect mode' that caused a wrong mode to be restored when loading a project or preset
#93 Fixed bug that could cause feedback MIDI messages to pile up while track disarmed or audio device off
#94 Fixed potentially incorrect feedback message for first target change after loading ReaLearn
#95 Fixed 'FX must have focus' not being respected for feedback
#98 Fixed crash after deleting track send used in track send target and opening ReaLearn window again
#99 Fixed weird scrollbar on OS X

1.1.0 2017-12-10

#41 Added experimental support for MIDI feedback (supported sources: CC value, note velocity, pitch wheel, channel after touch, program change, polyphonic after touch ... (N)RPN currently not; supported modes: absolute, toggle; supported targets: all, limited support for actions)
#56 Added possibility to enable/disable each mapping (control and feedback can be enabled/disabled separately - this feature makes it possible to correctly handle devices that expect different kinds of MIDI messages for feedback than they send when moving a control)
#68 Added possibility to go to target (e.g. scroll to track, open FX, ...) via 'Go there' button in mapping window
#53 Added target 'Track arm'
#57 Added source 'Polyphonic after touch'
#64 Added possibility to learn action target (so you don't have to choose the action in the long dropdown menu; just invoke the action while having 'Learn target' enabled and it will be selected)
#65 Added target visualisation for on/off actions
#58 Fixed bug that caused control surfaces to not be notified when volume and pan was changed through ReaLearn
#62 Fixed REAPER UI lags when using target value visualisation in mapping dialog
#63 Fixed serious audio and UI lags when having many targets under load
#60 Fixed audio crackling when opening ReaLearn UI
#66 Fixed non-working send volume target learning and visualisation
#59 Fixed some possible crashes (e.g. when loading ReaLearn in inactive project tab, when deleting tracks used in ReaLearn, when removing FX used in ReaLearn)

1.0.2 2017-02-05

#51 Fixed incorrectly displayed target track in dialog window (always showed previous track)

1.0.1 2016-12-24

#49 Fixed critical timing bug that caused MIDI messages to be forwarded (let through) slightly delayed

1.0.0 2016-12-23

#45 Added option "FX must have focus" to FX parameter target
#48 Fixed UI freeze on Windows when using action target by loading the complete set of action names not before clicking action dropdown
#43 Fixed superfluous invocation of trigger-style actions when releasing a MIDI switch (note or CC) by making it possible to specify an invocation type and making "Trigger" the default type (because most actions have trigger character)
#46 Fixed UI freeze when using (N)RPN source by replacing dropdown with text field
#44 Fixed unnecessary reload of action list

1.0.0-beta6 2016-11-17

#39 Improved invocation speed of actions
#40 Fixed still broken restoral of custom action targets

1.0.0-beta5 2016-11-11

#33 Improved usability by allowing input of source min/max values as discrete values, not as percental ones (that allows for far more precise setups)
#29 Improved usability and comprehensibility by working with percental values instead of values between 0 and 1
#28 Improved range of usable CCs: CCs 6, 38, 98, 99, 100 and 101 are now usable if (N)RPN is not used on that channel
#35 Improved stability by deferring to main thread much earlier in the processing chain
#20 Improved usability by not using more screen space than necessary, for example by reducing the space between mapping rows
#37 Improved supportability by including information about beta version in DLL file
#25 Fixed broken restoral of custom action targets
#30 Fixed broken text input for target value
#32 Fixed bug that caused the pitch wheel to never reach the highest possible value
#22 Fixed crash on REAPER project load after ReaLearn FX was renamed
#23 Fixed display of dummy values and incomplete values on REAPER project load for send volume targets
#31 Fixed bug that caused soft takeover (max jump) to lose track of the value and therefore misbehave
#34 Fixed REAPER freeze when writing send volume automation while FX multiprocessing enabled
#38 Fixed flipped UI in OS X ('Add mapping' button and checkboxes were on the buttom but they should have been on the top like on Windows)

1.0.0-beta4 2016-08-04

#11 Added new source '(N)RPN' for MIDI (N)RPN messages (both 7 and 14 bit)
#13 Added support for 14-bit CCs
#14 Added 'Max jump' slider to absolute mode for controlling soft-takeover behavior (also known as 'pickup')
#10 Fixed bug that caused volume control to be non-linear (now behaves exactly like the volume control action)
#12 Fixed action target so user interface stays responsive while loading actions
#15 Fixed REAPER freeze on project load when putting a plug-in in front of ReaLearn which sends MIDI messages
#17 Fixed weird behavior after duplicating mapping with FX parameter target (and probably also other target types)
#19 Fixed bug that caused mapping list to be out of date after duplicating tracks

1.0.0-beta3 2016-07-03

#9 Added new target 'Track pan'
#8 Added option 'Ignore out-of-range source values' and disable it by default (this only has an effect if you restrict the source range using the min/max sliders)
#5 Fixed bug that caused ReaLearn to misinterpret parameter modulation and automation as 'touch' events

1.0.0-beta2 2016-06-29

#3 Added action 'ReaLearn: Learn source for last touched target' for one-click MIDI learn (available as long as at least one ReaLearn FX loaded, I recommend to create a toolbar button for that)
#4 Fixed REAPER freeze when controlling FX parameter and writing new automation
#2 Fixed parameter jumps with JS effects
#1 Fixed pitch wheel range

1.0.0-beta 2016-06-11
