OBS Studio 21.1.0

General Changes
---------------
* Updated the Browser source to Chromium 63. This includes many important and critical updates to the Browser backend.

  - The new Chromium build for the browser source now supports APNG (animated PNG) image files.
  - Fixed a few bugs and a potential crash on shutdown with the browser source, with more fixes and improvements to come in coming updates.
  - Fixed a bug where the bit icons in certain donation alerts didn't load properly (fixed with the Chromium update for the browser source).

* Dockable windows can now be nested.
* Updated the program to use the latest Microsoft development toolchain (Visual Studio 2017) for the Windows version.

Bug Fixes
---------
* Fixed a bug where you could import a scene collection with an already-existing name.
* Fixed an issue where a spontaneous rare audio glitch could happen when encoding audio on Windows.  This was caused by a Microsoft audio encoder library which was used by default on Windows at bitrates between 96 and 192 kilobits per second; this library has now been replaced.
* Fixed a potential crash on startup.
* Fixed a few scripting-related crashes.
* Fixed a bug where setting a blank replay buffer prefix would reset to the default prefix when the program was restarted.
* Fixed a bug where the slideshow source would get stuck on the last image is the slideshow image list was cleared.
* Selection rectangles are no longer drawn for audio-only sources.

OBS Studio 21.0.3

21.0.3 Hotfix (macOS)
---------------------

* Updated the Qt version to 5.10.1 to fix crashes caused by Qt 5.10

21.0.2 macOS Release
--------------------

* Fixed an issue with Qt 5.10 moving the macOS theme to a plugin
* Additional packaging to make sure Lua works on macOS
* Fixed MP3 audio support in the browser source on macOS

Known Issues on macOS
---------------------

* Python scripting is currently disabled on macOS
* VST plugin sizing may be off on some systems (manually resize for now)

21.0.1 Hotfix
-------------

* Fixed a crash with the stinger transition.
* Fixed a bug where Hauppauge and Live Gamer Portable devices were not outputting audio/video.
* Fixed a lock on startup that could occur depending on how audio ducking was configured.

Scripting
---------

* Added Luajit/Python3 scripting support.  Scripting can be accessed via the "Tools" menu -> "Scripts".
* Lua is supported via Luajit, which comes with the program.  Lua is recommended for high performance scripts, automation, and sources.
* Python is available if access to its convenient libraries is desired.  On windows, to use Python, Python version 3.6 must be installed separately ("x86-64" version if 64bit OBS Studio, "x86" version if 32bit OBS Studio), and the Python 3.6 install path must be configured in the Python settings tab.
* Scripting documentation can be found in the developer documentation: https://obsproject.com/docs/scripting.html
* Added an example Lua script: An "Analog Clock" source which draws an analog clock (added like any other source when the script is active)
* Added an example Lua script: A "Countdown Timer" script which sets the text of a text source to a countdown timer which counts down when that text source is displayed on stream.
* Added an example Lua script: An "Instant Replay" script which automatically save a replay if there's an active replay buffer, and then plays back that replay in a specified media source after that replay has saved.
* Added an example Python script: A "URL Text" script which sets the text of a specified text source to the text downloaded from a specified URL every specified interval.

New Audio Features
------------------

* Added sidechain/ducking support to the compressor filter.  This allows the ability to lower the audio level of an audio source based upon how loud another source is.  For example, to apply microphone ducking to a desktop audio source, add a compressor filter to the desktop audio source, then select the microphone audio source in the "Sidechain/Ducking Source" property.
* Added surround sound audio output support, which allows outputting 2.1, 4.0, 4.1, 5.1, and 7.1 audio to stream/recording.  (When using this feature, please also make sure to increase your audio bitrate to support all the channels in output settings.  Although some services like Twitch support it, note that certain services such as YouTube may not fully support surround sound streaming, and may not downmix them correctly for stereo viewers)
* Added new audio meters to allow the ability to see the audio levels of each audio channel of that source.  This allows the ability to know if there are any issues with a specific audio channel (e.g. if just the left or right audio channel is somehow low or muted).
* Changed audio meters to behave like peak programme meters.  This will make it easier to see if your audio is clipping and set your audio levels correctly.  For more information, see:  https://obsproject.com/wiki/Understanding-The-Mixer
* Added an "Audio Meter Decay Rate" option in audio settings to allow selecting a specific delay rate (fast, medium, slow) for the audio meters if desired.
* Added the ability to rename audio sources via right-clicking them in the audio mixer, including desktop and microphone audio capture sources added via audio settings.

New Production and Studio Mode Features
---------------------------------------

* Added a "Multiview" projector (accessible via the View menu), which allows the ability to view the preview/program and up to 8 scenes at the same time.  Scenes in the Multiview can be clicked to change the scene (or the preview scene in studio mode).  You can blacklist certain scenes from displaying in the multi-view by right-clicking the scene in the scenes list and unchecking "Show in Multiview".  You can also change the Multiview's layout style in general settings.
* Added an option in general settings that allows you to transition to a scene in studio mode simply by double-clicking on it.  This also applies to the multiview projector.
* Added separate projectors for both preview and program views in studio mode.
* Added a portrait/vertical layout option for studio mode in general settings which makes the preview/program views vertical relative to each other instead of horizontal
* Added per-scene transition overriding, which allows you to select a specific transition to use for a specific scene.  To use this feature, right-click on the scene in the scene list, and select the transition/duration via the right-click context menu.  (This override does not apply to studio mode quick transitions)

Developer Documentation
-----------------------

* Spent about a week or so and finally wrote full developer API documentation/reference (useful for both native and script developers), which can be found here: https://obsproject.com/docs

Other General Changes and Fixes
-------------------------------

* Added a new program theme: Acri.
* Changed the default program theme to dark mode for new users.
* Changed the text of "Multi-adapter Compatibility" in game capture to "SLI/Crossfire Capture Mode (Slow)".  This was changed because the wording "Multi-adapter Compatibility" was a bit vague, and users are not typically aware of the potential performance impact when using the option.
* Optimized the preview pane and reduced GPU usage by 2-8% depending on how many sources were in the preview.
* The streaming/recording buttons in the main window now highlight while streaming/recording.
* Fixed a bug on Windows where desktop audio capture could go slightly out of sync with display/game/window capture on certain audio devices
* Fixed an issue where certain Elgato devices would not output audio by default, and would require users to select the audio device manually.
* Fixed a bug with studio mode where scenes that are set to fully duplicate would not retain their filters.
* Fixed a stuttering bug on Linux with audio monitoring
* Fixed MP3 audio support in the browser source on macOS
* Fixed a few Dark/Rachni theme issues
* Fixed a lot of minor bugs and a few minor memory leaks
* Fixed a known crash that could happen on startup for certain AMD cards/drivers.

OBS Studio 19.0.3

19.0.3 Hotfix Changes
---------------------
* When an audio device in audio settings is changed to different device, all of its secondary settings are now preserved (volume, sync offset, downmix to mono, mixer, properties, filters).  Note that this does not apply if the audio device is disabled.
* Fixed an issue where Oculus Rift games wouldn't capture properly with game capture on Windows
* Fixed a case where the bandwidth test could potentially overestimate bandwidth in the auto-configuration tool
* Fixed an issue where remote video via the media source could have artifacting
* Fixed some cases where the media source wouldn't properly display the last frame when "Hide source when playback ends" is unchecked
* Fixed some cases where the media source could cause the program to freeze when using a remote video URL
* Fixed a design flaw where the stats window would reset all its values when opened for the first time

OBS Studio 19.0.2

19.0.2 Hotfix Changes
---------------------
* Fixed a startup crash with older AMD drivers when using the 32bit version of OBS.  Please update your video drivers!
* Fixed a bug that caused Freetype 2 text sources to stop rendering properly on windows
* Fixed an issue with NVENC not initializing properly for some people on older drivers
* Fixed a tooltip that's supposed to show when you hover over "prefer hardware encoding" in the auto-configuration wizard

19.0.1 Hotfix Changes
---------------------
* Fixed a bug where the auto-configuration wizard would sometimes not save settings
* Fixed a bug where if you press cancel/back while connecting during a bandwidth test the program would freeze indefinitely
* Fixed a bug where unintentional whitespace would not be removed from the end of the stream key, and would cause connection to fail when performing a bandwidth test with the auto-configuration wizard
* Fixed an issue where the AMD encoder would no longer be usable in the 64bit version
* Fixed a crash when using certain lossless RGB media files with the new media source

19.0 General Changes
--------------------
* Added an auto-configuration wizard to the tools menu and on first-time use, which will attempt to automatically test and configure video/encoding/streaming settings based upon your system and internet connection.  This wizard is currently in beta and may be subject to change, feedback is appreciated.
* Added a stats dialog to the view menu (with the option to show it on start it up in general settings).  The stats dialog shows advanced statistics, such as: average frame rendering time, frames lost due to encoding/rendering/network lag, HDD space left in recording location, and how much data has been output total.
* Added a "Render Delay" filter that allows delaying non-async video sources such as display capture or window capture.  Note this is only meant for minor sync adjustments (e.g. syncing your screen capture to a webcam), and because the delayed frames are stored on very limited VRAM, the allowable maximum delay is 500 milliseconds (which is 250 megabytes of VRAM on a 1080p 60 FPS source)
* Added the ability to copy and paste filters between sources
* Added Ctrl-E as a shortcut to edit transform of sources
* Added a command line option to start as always on top (--always-on-top)

* Added an option to the blackmagic source that allows you to specify the channel format
* Added the ability to project a source, scene, or the preview on to a resizable window in the right-click context menu when right-clicking on sources or the preview
* Reworked the media source: media files set to activate when switching to a scene will now immediately start play back when you switch to their scene without requiring time to load
* Reworked the media source: media files will now loop properly with no abnormalities in sound playback
* Fixed a bug where scenes could be unintentionally lost under specific crash circumstances (backup files were always present, but were not being used -- this is now fixed)
* Fixed an issue where the blackmagic source can start up or spontaneously go out of sync
* Fixed dragging and dropping text files to create a text source on non-windows systems
* Fixed a bug where devices outputting NV12 (e.g. Logitech BRIO cams) would have distorted colors
* Fixed a bug where frame dropping would not happen properly when using the ultrafast x264 preset
* Fixed a bug from 18.0.2 where "downmix to mono" would no longer save
* Fixed a potential crash under specific circumstances when OBS is set to minimize to task tray
* When dragging and dropping text files to create a source, those sources will now have the same name as the text file being dropped
* All dialogs should now have close buttons (useful on certain window managers such as gnome)
* Filter names are now sorted when adding new filters

19.0 Windows Changes
--------------------
* Added an option to disable audio ducking on windows, now on by default.  Prevents the system from lowering volume of programs when the mic is activated by OBS
* Added HEVC recording support to the AMD encoder
* Added Two-Pass and Full-Range color support to the AMD encoder

* Fixed an issue where the device source would activate on startup even when it's in another scene and set to deactivate when not visible
* Fixed and clarified window capture prioritization.  "Title" will now match any window of the exact window title, "class" will try to find a window by the title otherwise match any window of the same window type, and "exe" will match any window of the same title or if not found any window of the same program.
* Fixed a crash when using QSV to encode
* Fixed a bug where log files wouldn't be created when the current windows user had unicode characters in the name
* Fixed an issue with the AMD encoder which would make it difficult to seek on certain file types
* (Repeating 18.0.2 in case it was missed) Fixed poor game capture performance with some DirectX 9 games on the Windows 10 "Creator's Update" as well as some cases Windows 7

19.0 Linux Changes
