[Unreleased]

Added

• During VST2 audio processing, yabridge will now prefetch the current transport information and the process level before sending the audio buffers to the Windows VST2 plugin. This lets us cache this information during the audio processing call, which significantly reduces the overhead of bridging VST2 plugins by avoiding one or more otherwise mandatory back and forth function call between yabridge's plugin and the Wine plugin host. This has an even greater impact on plugins like SWAM Cello that request this information repeatedly over the course of a single audio processing cycle. Previously yabridge had a cache_time_info compatibility option to mitigate the performance hit for those plugins, but this new caching behaviour supercedes that.
• We now always force the CPU's flush-to-zero flag to be set when processing audio. Most plugins will already do this themselves, but plugins like Kush Audio REDDI and Expressive E Noisy that don't will otherwise suffer from extreme DSP usage increases when processing almost silent audio.
• Added a new compatibility option to hide the name of the DAW you're using for a plugin. This can be useful with plugins that have undesirable or broken DAW-specific behaviour. See the known issues section of the readme for more information on when this may be useful.
• Yabridge would always try to gracefully shut down the Wine plugin host processes when the native host crashes or gets killed for whatever reason, but this did not always happen if the crash occurred before the bridged plugin has finished initializing because of the way Unix Domain Sockets work. In that specific situation the yabridge-host.exe process would be left running indefinitely, and that might have also prevented you from being able to start your DAW depending on the DAW. To prevent any more dangling processes, yabridge's Wine plugin hosts now have a watchdog that periodically checks whether the original process that spawned the bridges is still running. If it detects that the process is no longer alive, yabridge will close the sockets and shut down the bridged plugin to prevent any dangling processes from sticking around.

Changed

• When building the package from source, the targetted Wine version now gets printed at configure-time. This can make it a bit easier to diagnose Wine-related compilation issues.
• Yabridge has always automatically handled most common VST2 functions by simply inspecting the argument types. This works practically everywhere, but Plugsound Free by UVI would pass unreadable function arguments to functions that weren't not supposed to have any arguments, causing yabridge to crash. To prevent similar situations from happening in the future, yabridge now specifically handles most common VST2 functions that don't have a data argument.
• Instead of trying to proxy VST3 connection point proxies used by the host, yabridge will now first try to bypass the proxy instead, only falling back to proxying the proxy when that's not possible. This only affects Ardour and Mixbus. This greatly improves compatibility with FabFilter plugins in those DAWs.
• The build has been slightly slimmed down using static libraries.

Removed

• The cache_time_info compatibility option has been removed since it's now obsolete.
• Removed a message that would show up when loading a VST3 plugin in Ardour, warning about potential crashes due to Ardour not supporting multiple input and output busses. These crashes have been resolved since yabridge 3.1.0.

Fixed

• In certain rare circumstances, closing a plugin editor would trigger an X11 error and crash the Wine plugin host and with that likely the entire DAW. This happened because Wine would try to destroy a window that had already been destroyed. This could happen in Renoise and to a lesser degree in REAPER with plugins that take a while to close their editors, such as the iZotope Rx plugins. We now explicitly reparent the window to back the root window first before deferring the window closing. This should fix the issue, while still keeping editor closing nice and snappy.
• Allow plugin group host processes to shut down by themselves if it doesn't get a request to host any plugins. This can happen when the DAW gets killed after starting the group host process but before the native yabridge plugins requests the group host process to host a plugin.
• Prevented latency introducing plugins VST3 from causing Ardour and Mixbus to freeze when loading the plugin. This for example prevents Neural DSP Darkglass from freezing when used under those DAWs.
• Fixed FabFilter VST3 plugins freezing in Ardour and Mixbus when trying to duplicate existing instances of the plugin while the GUI editor is open.
• Fixed VST3 plugins freezing in Ardour and Mixbus when the plugin tries to automate a parameter while loading a preset.
• Fixed Voxengo VST3 plugins freezing in Ardour and Mixbus when loading a project or when duplicating the plugin instances.
• Fixed potential X11 errors resulting in assertion failures and crashes in Ardour and Mixbus by ignoring X11 events after those hosts hides the editor window.
• Fixed a regression from yabridge 3.1.0 where REAPER would freeze when opening a VST3 plugin context menu.
• Fixed a potential assertion failure when setting VST3 preset data. This would depend on the libstdc++ version used to built yabridge with.
• PSPaudioware InifniStrip would fail to initialize because the plugin expects the host to always be using Microsoft COM and it won't initialize it by itself. InfiniStrip loads as expected now.
• Native Instruments' FM7 would crash when processing MIDI. As a fix, MIDI events are now deallocated later then when they normally would have to be.
• Fixed extreme DSP usage increases in Kush Audio REDDI and Expressive E Noisy caused by denormals.
• Fixed the VST3 version of W. A. Production ImPerfect from crashing during audio setup.
• Fixed UVI Plugsound Free crashing during initialization.
• Fixed potential freezing when loading a VST3 preset that tries to resize an open editor window.
• Because of the new transport information prefetching, the excessive DSP usage in SWAM Cello is now been fixed without requiring any manual compatibility options.
• Fixed the Wine version detection when using a custom WINELOADER.

[3.1.0] - 2021-04-15

Added

• Added support for using 32-bit Windows VST3 plugins in 64-bit Linux VST3 hosts. This had previously been disabled because of a hard to track down corruption issue.
• Added an option to prefer the 32-bit version of a VST3 plugin over the 64-bit version if both are installed. This likely won't be necessary, but because of the way VST3 bundles work there's no clean way to separate these. So when both are installed, the 64-bit version gets used by default.

Fixed

• Worked around a regression in Wine 6.5 that would prevent yabridge from shutting down (wine bug #50869). With Wine 6.5 terminating a Wine process no longer terminates its threads, which would cause yabridge's plugin and host components to wait for each other to shut down.
• Fixed preset/state loading in both the VST2 and VST3 versions of Algonaut Atlas 2.0 by loading and saving plugin state from the main GUI thread.
• Added a workaround for a bug present in every current Bluecat Audio VST3 plugin. Those plugins would otherwise crash yabridge because they didn't directly expose a core VST3 interface through their query interface.
• Fixed a multithreading related memory error in the VST3 audio processor socket management system.

yabridgectl

• Added an indexing blacklist, accessible through yabridgectl blacklist. You most likely won't ever have to use this, but this lets you skip over files and directories in yabridgectl's indexing process.
• Minor spelling fixes.

Packaging notes

• The Meson wrap dependencies for bitsery, function2 and tomlplusplus are now defined using dependency() with a subproject fallback instead of using subproject() directly. This should make it easier to package.
• The VST3 SDK Meson wrap dependency and the patches in tools/patch-vst3-sdk.sh are now based on version 3.7.2 of the SDK.
• The VST3 SDK Meson wrap now uses a tag (v3.7.2_build_28-patched) instead of a commit hash.

[3.0.2] - 2021-03-07

Fixed

• Fix bus information queries being performed for the wrong bus index. This fixes VST3 sidechaining in Renoise, and prevents a number of VST3 plugins with a sidechain input from causing Ardour and Mixbus to freeze or crash.

[3.0.1] - 2021-02-26

Changed

• Wine 6.2 introduced a regression that would cause compile errors because some parts of Wine's headers were no longer valid C++. Since we do not need the affecting functionality, yabridge now includes a small workaround to make sure that the affected code never gets compiled. This has been fixed for Wine 6.3.

Fixed

• Added support for a new ReaSurround related VST2.4 extension that REAPER recently started using. This would otherwise cause certain plugins to crash under REAPER.
• Fixed a regression from yabridge 3.0.0 where log output would no longer include timestamps.

yabridgectl

• Changed the wording and colors in yabridgectl status for plugins that have not yet been setup to look less dramatic and hopefully cause less confusion.
• Aside from the installation status, yabridgectl status now also shows a plugin's type and architecture. This is color coded to make it easier to visually parse the output.
• Plugin paths printed during yabridgectl status and yabridgectl sync --verbose are now always shown relative to the plugin directory instead of the same path prefix being repeated for every plugin.

[3.0.0] - 2021-02-14

Added

• Yabridge 3.0 introduces the first ever true Wine VST3 bridge, allowing you to use Windows VST3 plugins in Linux VST3 hosts with full VST 3.7.1 compatibility. Simply tell yabridgectl to look for plugins in $HOME/.wine/drive_c/Program Files/Common Files/VST3, run yabridgectl sync, and your VST3 compatible DAW will pick up the new plugins in ~/.vst3/yabridge automatically. Even though this feature has been tested extensively with a variety of VST3 plugins and hosts, there's still a substantial part of the VST 3.7.1 specification that isn't used by any of the hosts or plugins we could get our hands on, so please let me know if you run into any weird behaviour! There's a list in the readme with all of the tested hosts and their current VST3 compatibility status.
• Added an option to use Wine's XEmbed implementation instead of yabridge's normal window embedding method. This can help reduce flickering when dragging the window around with certain window managers. Some plugins will have redrawing issues when using XEmbed or the editor might not show up at all, so your mileage may very much vary.
• Added a compatibilty option to forcefully enable drag-and-drop support under REAPER. REAPER's FX window reports that it supports drag-and-drop itself, which makes it impossible to drag files onto a plugin editor embedded there. This option strips the drag-and-drop support from the FX window, thus allowing you to drag files onto plugin editors again.
• Added a frame rate option to change the rate at which events are being handled. This usually also controls the refresh rate of a plugin's editor GUI. The default 60 updates per second may be too high if your computer's cannot keep up, or if you're using a host that never closes the editor such as Ardour.
• Added a compatibility option to disable HiDPI scaling for VST3 plugins. At the moment Wine does not have proper fractional HiDPI support, so some plugins may not scale their interfaces correctly when the host tells those plugins to scale their GUIs. In some cases setting the font DPI in winecfg's graphics tab to 192 will also cause the GUIs to scale correctly at 200%.
• Added the with-vst3 compile time option to control whether yabridge should be built with VST3 support. This is enabled by default.

Changed

• libyabridge.so is now called libyabridge-vst2.so. If you're using yabridgectl then nothing changes here. To avoid any potential confusion in the future, please remove the old libyabridge.so file before upgrading.

• The release archives uploaded on GitHub are now repackaged to include yabridgectl for your convenience.

• Window closing is now deferred. This means that when closing the editor window, the host no longer has to wait for Wine to fully close the window. Most hosts already do something similar themselves, so this may not always make a difference in responsiveness.

• Slightly increased responsiveness when resizing plugin GUIs by preventing unnecessary blitting. This also reduces flickering with plugins that don't do double buffering.

• VST2 editor idle events are now handled slightly differently. This should result in even more responsive GUIs for VST2 plugins.

• Win32 and X11 events in the Wine plugin host are now handled with lower scheduling priority than other tasks. This might help get rid of potential DSP latency spikes when having the editor open while the plugin is doing expensive GUI operations.

• Opening and closing plugin editors is now also no longer done with realtime priority. This should get rid of any latency spikes during those operations, as this could otherwise steal resources away from the threads that are processing audio.

• The way realtime priorities assigned has been overhauled:

  • Realtime scheduling on the plugin side is now a more granular. Instead of setting everything to use SCHED_FIFO, only the spawned threads will be configured to use realtime scheduling. This prevents changing the scheduling policy of your host's GUI thread if your host instantiates plugins from its GUI thread like REAPER does.
  • Relaying messages printed by the plugin and Wine is now done without realtime priority, as this could in theory cause issues with plugins that produce a steady stream of fixmes or other output.
  • The realtime scheduling priorities of all audio threads in the Wine plugin host are now periodically synchronized with those of the host's audio threads.

• When using yabridge.toml config files, the matched section or glob pattern is now also printed next to the path to the file to make it a bit easier to see where settings are being set from.

• The architecture document has been updated for the VST3 support and it has been rewritten to talk more about the more interesting bits of yabridge's implementation.

• Part of the build process has been changed to account for this Wine bug. Building with Wine 5.7 and 5.8 required a change for yabridge-host.exe to continue working, but that change now also breaks builds using Wine 6.0 and up. The build process now detects which version of Wine is used to build with, and it will then apply the change conditionally based on that to be able to support building with both older and newer versions of Wine. This does mean that when you switch to an older Wine version, you might need to run meson setup build --reconfigure before rebuilding to make sure that these changes take effect.

• yabridge-host.exe will no longer remove the socket directories if they're outside of a temporary directory. This could otherwise cause a very unpleasant surprise if someone were to pass random arguments to it when for instance trying to write a wrapper around yabridge-host.exe.

• When YABRIDGE_DEBUG_LEVEL is set to 2 or higher and a plugin asks the host for the current position in the song, yabridge will now also print the current tempo to help debugging host bugs.

Fixed

• VST2 plugin editor resizing in REAPER would not cause the FX window to be resized like it would in every other host. This has now been fixed.
• The function for suspending and resuming audio, effMainsChanged(), is now always executed from the GUI thread. This fixes EZdrummer not producing any sound because the plugin makes the incorrect assumption that effMainsChanged() is always called from the GUI thread.
• Event handling is now temporarily disabled while plugins are in a partially initialized state. The VST2 versions of T-RackS 5 would have a chance to hang indefinitely if the event loop was being run before those plugins were fully initialized because of a race condition within those plugins. This issue was only noticeable when using plugin groups.
• Fixed a potential issue where an interaction between Bitwig Studio and yabridge's input focus grabbing method could cause delayed mouse events when clicking on a plugin's GUI in Bitwig. This issue has not been reported for yabridge 2.2.1 and below, but it could in theory also affect older versions of yabridge.

yabridgectl

• Updated for the changes in yabridge 3.0. Yabridgectl now allows you to set up yabridge for VST3 plugins. Since libyabridge.so got renamed to libyabridge-vst2.so in this version, it's advised to carefully remove the old libyabridge.so and yabridgectl files before upgrading to avoid confusing situations.
• Added the yabridgectl set --path-auto option to revert back to automatically locating yabridge's files after manually setting a path with yabridgectl set --path=<...>.
• Added the yabridgectl set --no-verify={true,false} option to permanently disable post-installation setup checks. You can still directly pass the --no-verify argument to yabridgectl sync to disable these checks for only a single invocation.

[2.2.1] - 2020-12-12

Fixed

• Fixed some plugins, notably the Spitfire Audio plugins, from causing a deadlock when using plugin groups in REAPER. Even though this did not seem to cause any issues in other hosts, the race condition that caused this issue could also occur elsewhere.

[2.2.0] - 2020-12-11

Added

• Added an option to cache the time and tempo info returned by the host for the current processing cycle. This would normally not be needed since plugins should ask the host for this information only once per audio callback, but a bug in SWAM Cello causes this to happen repeatedly for every sample, resutling in very bad performance. See the compatibility options section of the readme for more information on how to enable this.

Changed

• When YABRIDGE_DEBUG_LEVEL is set to 2 or higher and a plugin asks the host for the current position in the song, yabridge will now print that position in quarter notes and samples as part of the debug output.
• YABRIDGE_DEBUG_LEVEL 2 will now also cause all audio processing callbacks to be logged. This makes recognizing misbheaving plugins a bit easier.
• Symbols in all libyabridge.so and all Winelib .so files are now hidden by default.

Fixed

• Fixed an issue where in certain situations Wine processes were left running after the host got forcefully terminated before it got a chance to tell the plugin to shut down. This could happen when using Kontakt in Bitwig, as Bitwig sets a limit on the amount of time a plugin is allowed to spend closing when you close Bitwig, and Kontakt can take a while to shut down.
• Fixed a potential crash or freeze when removing a lot of plugins from a plugin group at exactly the same time.

[2.1.0] - 2020-11-20

Added

• Added a separate yabridgectl AUR package for Arch and Manjaro. The original idea was that yabridgectl would not require a lot of changes and that a single yabridgectl-git package would be sufficient, but sometimes changes to yabridgectl will be incompatible with the current release so it's nicer to also have a separate regular package.

Changed

• Yabridge will now always search for yabridge-host.exe in ~/.local/share/yabridge even if that directory is not in the search path. This should make setup easier, since you no longer have to modify any environment variables when installing yabridge to the default location. Because of this, the symlink-based installation method does not have a lot of advantages over the copy-based method anymore other than the fact that you can't forget to rerun yabridgectl sync after an upgrade, so most references to it have been removed from the readme.

Fixed

• Fixed an issue where Renoise would show an error message when trying to load a plugin in the mixer.

[2.0.2] - 2020-11-14

Fixed

• Added a workaround for a bug in Ardour 6.3 which would cause several plugins including MT Power Drumkit to crash when opening the editor.
• Fixed linking error in debug build related to the parallel STL.

[2.0.1] - 2020-11-08

Fixed

• Fixed a regression where yabridge-host.exe would not exit on its own after the host crashes or gets terminated without being able to properly close all plugins.

[2.0.0] - 2020-11-08

Added

• The way communication works in yabridge has been completely redesigned to be fully concurrent and to use additional threads as necessary. This was needed to allow yabridge to handle nested and mutually recursive function calls as well as several other edge cases a synchronous non-concurrent implementation would fail. What this boils down to is that yabridge became even faster, more responsive, and can now handle many scenarios that would previously require workarounds. The most noticeable effects of these changes are as follows:

  • The hack_reaper_update_display workaround for REAPER and Renoise to prevent certain plugins from freezing is no longer needed and has been removed.
  • Opening and scanning plugins becomes much faster in several VST hosts because more work can be done simultaneously.
  • Certain plugins, such as Kontakt, no longer interrupt audio playback in Bitwig while their editor was being opened.
  • Any loading issues in Bitwig Studio 3.3 beta 1 are no longer present.
  • Hosting a yabridged plugin inside of the VST2 version of Carla now works as expected.
  • And probably many more improvements.

  Aside from these more noticeable changes, this has also made it possible to remove a lot of older checks and behaviour that existed solely to work around the limitations introduced by the old event handling system. I have been testing this extensively to make sure that these changes don't not introduce any regressions, but please let me know if this did break anything for you.

Changed

• The way the Wine process handles threading has also been completely reworked as part of the communication rework.
• GUI updates for plugins that don't use hardware acceleration are now run at 60 Hz instead of 30 Hz. This was kept at 30 updates per second because that seemed to be a typical rate for Windows VST hosts and because function calls could not be processed while the GUI was being updated, but since that limitation now no longer exists we can safely bump this up.
• Sockets are now created in $XDG_RUNTIME_DIR (which is /run/user/<user_id> on most systems) instead of /tmp to avoid polluting /tmp.

Removed

• The now obsolete hack_reaper_update_display option has been removed.
• The previously deprecated use-bitbridge and use-winedbg compilation options have been removed. Please use with-bitbridge and with-winedbg instead.

Fixed

• Fixed a very long standing issue with plugins groups where unloading a plugin could cause a crash. Now you can host over a hundred plugins in a single process without any issues.
• Fixed another edge case with plugin groups when simultaneously opening multiple plugins within the same group. The fallover behaviour that would cause all of those plugins to eventually connect to a single group host process would sometimes not work correctly because the plugins were being terminated prematurely.
• Fixed the implementation of the accumulative process() function. As far as I'm aware no VST hosts made in the last few decades even use this, but it just feels wrong to have an incorrect implementation as part of yabridge.

[1.7.1] - 2020-10-23

Fixed

• Fixed a regression where the editor_double_embed option would cause X11 errors and crash yabridge.
• Fixed a regression where certain fake dropdown menus such as those used in the Tokyo Dawn Records plugins would close immediately when hovering over them.
• Fixed an issue where plugins hosted within a plugin group would not shut down properly in certain situations. This would cause the VST host to hang when removing such a plugin.

yabridgectl

• When running yabridgectl sync, existing .so files will no longer be recreated unless necessary. This prevents hosts from rescanning all plugins after setting up a single new plugin through yabridgectl. Running yabridgectl sync after updating yabridge will still recreate all existing .so files as usual.
• Added a --force option to yabridgectl sync to always recreate all existing .so files like in previous versions.
• Fixed a regression from yabridgectl 1.6.1 that prevented you from removing directories that no longer exist using yabridgectl rm.

[1.7.0] - 2020-10-13

Changed

• The way keyboard input works has been completely rewritten to be more reliable in certain hosts and to provide a more integrated experience. Hovering over the plugin's editor while the window provided by the host is active will now immediately grab keyboard focus, and yabridge will return input focus to the host's window when moving the mouse outside of the plugin's editor when the window is still active. This should fix some instances where keyboard input was not working in hosts with more complex editor windows like REAPER and Ardour, and it also allows things like the comment field in REAPER's FX window to still function.

  A consequence of this change is that pressing Space in Bitwig Studio 3.2 will now play or pause playback as intended, but this does mean that it can be impossible to type the space character in text boxes inside of a plugin editor window. Please let me know if this causes any issues for you.

• Both unrecognized and invalid options are now printed on started to make debugging yabridge.toml files easier.

• Added a note to the message stating that libSwell GUI support has been disabled to clarify that this is expected behaviour when using REAPER. The message now also contains a suggestion to enable the hack_reaper_update_display option when it is not already enabled.

Fixed

• Added a workaround for reparenting issues with the plugin editor GUI on a specific i3 setup.

Documentation

• The documentation on yabridge.toml files and the available options has been rewritten in an effort to make it easier to comprehend.

[1.6.1] - 2020-09-28

Fixed

• Fixed a potential crash that could happen if the host would unload a plugin immediately after its initialization. This issue affected the plugin scanning in REAPER.
• Fixed parsing order of yabridge.toml. Sections were not always read from top to bottom like they should be, which could cause incorrect and unexpected setting overrides.
• Fixed an initialization error when using plugin groups for plugins that are installed outside of a Wine prefix.

yabridgectl

• Relative paths now work when adding plugin directories or when setting the path to yabridge's files.
• Also search /usr/local/lib for libyabridge.so when no manual path has been specified. Note that manually copying yabridge's files to /usr is still not recommended.

[1.6.0] - 2020-09-17

Added

• Added support for double precision audio processing. This is not very widely used, but some plugins running under REAPER make use of this. Without this those plugins would cause REAPER's audio engine to crash.

Fixed

• Increased the limit for the maximum number of audio channels. This could cause issues in Renoise when using a lot of output channels.

[1.5.0] - 2020-08-21

Added

• Added an option to work around timing issues in REAPER and Renoise where the hosts can freeze when plugins call a certain function while the host doesn't expect it, see #29 and #32. The readme contains instructions on how to enable this.

Changed

• Don't print calls to effIdle() when YABRIDGE_DEBUG_LEVEL is set to 1.

Fixed

• Fix Waves plugins from freezing the plugin process by preventing them from causing an infinite message loop.

[1.4.1] - 2020-07-27

yabridgectl

• Fixed regression caused by alexcrichton/toml-rs#256 where the configuration file failed to parse after running yabridgectl sync. If you have already run yabridgectl sync using yabridgectl 1.4.0, then you'll have to manually remove the [last_known_config] section from ~/.config/yabridgectl/config.toml.
• Fixed issue with overwriting broken symlinks during yabridgectl sync.

[1.4.0] - 2020-07-26

Added

• Added an alternative editor hosting mode that adds yet another layer of embedding. Right now the only known plugins that may need this are PSPaudioware plugins with expandable GUIs such as E27. The behaviour can be enabled on a per-plugin basis in the plugin configuration. See the readme for more details.

Changed

• Both parts of yabridge will now run with realtime priority if available. This can significantly reduce overall latency and spikes. Wine itself will still run with a normal scheduling policy by default, since running wineserver with realtime priority can actually increase the audio processing latency although it does reduce the amount of latency spikes even further. You can verify that yabridge is running with realtime priority by looking for the realtime: line in the initialization message. I have not found any downsides to this approach in my testing, but please let me know if this does end up causing any issues.

Fixed

• Fixed rare plugin location detection issue on Debian based distros related to the plugin and host detection fix in yabridge 1.2.0.

yabridgectl

• Added a check to yabridgectl sync that verifies that the currently installed versions of Wine and yabridge are compatible. This check will only be repeated after updating either Wine or yabridge.

• Added a --no-verify option to yabridgectl sync to skip the post-installation setup checks. This option will skip both the login shell search path check for the copy-based installation method as well as the new Wine compatibility check.

[1.3.0] - 2020-07-17

Added

• By somewhat popular demand yabridge now comes with yabridgectl, a utility that can automatically set up and manage yabridge for you. It also performs some basic checks to ensure that everything has been set up correctly so you can get up and running faster. Yabridgectl can be downloaded separately from the GitHub releases page and its use is completely optional, so you don't have to use it if you don't want to. Check out the readme for more information on how it works.

Deprecated

• The use-bitbridge and use-winedbg options have been deprecated in favour of the new with-bitbridge and with-winedbg options. The old options will continue to work until they are removed in yabridge 2.0.0.

[1.2.1] - 2020-06-20

Changed

• When building from source, only statically link Boost when the with-static-boost option is enabled.
• The use-bitbridge and use-winedbg options have been replaced by with-bitbridge and with-winedbg for consistency's sake. The old options will be marked as deprecated in the next minor release.

Fixed

• Fixed memory error that would cause crashing on playback with some buffer sizes in Mixbus6.
• Opening a plugin would override the Wine prefix for all subsequent plugins opened from within the same process. This prevented the use of multiple Wine prefixes in hosts that do not sandbox their plugins, such as Ardour.
• Manual Wine prefix overides through the WINEPREFIX environment were not reflected in the output shown on startup.
• Fixed plugin group socket name generation. This would have prevented plugin groups with the same name from being used simultaneously in different Wine prefixes.
• Distinguish between active processes and zombies when checking whether a group host process is still running during initialization.

[1.2.0] - 2020-05-29

Added

• Added the ability to host multiple plugins within a single Wine process through plugin groups. A plugin group is a user-defined set of plugins that will be hosted together in the same Wine process. This allows multiple instances of plugins to share data and communicate with each other. Examples of plugins that can benefit from this are FabFilter Pro-Q 3, MMultiAnalyzer, and the iZotope mixing plugins. See the readme for instructions on how to set this up.

Changed

• Changed architecture to use one fewer socket.
• GUI events are now always handled on a steady timer rather than being interleaved as part of the event loop. This change was made to unify the event handling logic for individually hosted plugins and plugin groups. It should not have any noticeable effects, but please let me know if this does cause unwanted behavior.

Fixed

• Steal keyboard focus when clicking on the plugin editor window to account for the new keyboard focus behavior in Bitwig Studio 3.2.
• Fixed large amount of empty lines in the log file when the Wine process closes unexpectedly.
• Made the plugin and host detection slightly more robust.

[1.1.4] - 2020-05-12

Fixed

• Fixed a static linking issue with the 32-bit build for Ubuntu 18.04.

[1.1.3] - 2020-05-12

Fixed

• Added a workaround for the compilation issues under Wine 5.7 and above as caused by Wine bug #49138.
• Added a workaround for plugins that improperly defer part of their initialization process without telling the host. This fixes startup behavior for the Roland Cloud plugins.
• Added a workaround for a rare race condition in certain plugins caused by incorrect assumptions in plugin's editor handling. Fixes the editor for Superior Drummer 3 and the Roland Cloud synths in Bitwig Studio.
• Fixed potential issue with plugins not returning their editor size.

[1.1.2] - 2020-05-09

Fixed

• Fixed an issue where plugin removal could cause Ardour and Mixbus to crash.

[1.1.1] - 2020-05-09

Changed

• Changed installation recommendations to only install using symlinks with hosts that support individually sandboxed plugins.
• Respect YABRIDGE_DEBUG_FILE when printing initialization errors.

Fixed

• Stop waiting for the Wine VST host process on startup if the process has crashed or if Wine was not able to start.

[1.1.0] - 2020-05-07

Added

• Added support for plugins that send MIDI events back to the host. This allows plugins such as Cthulhu and Scaler to output notes and CC for another plugin to work with.
• Added support for querying and setting detailed information about speaker configurations for use in advanced surround setups. This indirectly allows yabridge to work under Renoise.
• Added automated development builds for yabridge, available by clicking on the 'Automated builds' badge in the project readme.

Changed

• Changed the plugin detection mechanism to support yet another way of symlinking plugins. Now you can use a symlink to a copy of libyabridge.so that's installed for a plugin in another directory. This is not recommended though.
• Changed Wine prefix detection to be relative to the plugin's .dll file, rather than the loaded .so file.
• Increased the maximum number of audio channels from 32 to 256.
• Clarified the error that appears when we're unable to load the .dll.
• Yabridge will now print the used version of Wine during startup. This can be useful for diagnosing startup problems.

Fixed

• Fixed plugins failing to load on certain versions of Ubuntu because of paths starting with two forward slashes.
• Redirect the output from the Wine host process earlier in the startup process. Otherwise errors printed during startup won't be visible, making it very hard to diagnose problems.
