Changes for v24.0.3 - v25.0

New Features
Added the ability to capture Vulkan-based games with game capture. Big thanks to Ubisoft Montreal for submitting this feature! [Littlematth/jpark37/Jim]
Added a new capture method to window capture which allows capturing browsers, browser-based windows, and Microsoft Store (UWP) programs [jpark37]
By default, it will use "Automatic", which will use the normal method on most windows, and the new method on browsers, browser-based windows, and Microsoft Store (UWP) programs
The downside of the new method is that it can cause a bit of cursor lag, as well as a highlighted border around the captured window. The border itself does not get captured, however.
You can choose which capture method to use in window capture properties
Added advanced scene collection importing (on the menu bar, Scene Collection -> Import) which allows you to import from other common streaming programs [Dillon]
Added Media source hotkeys to allow control of playback (stop/pause/play/restart) [cg2121]
For now, these are just hotkeys. User interface for this is also planned for future updates
Added the ability to drag and drop URLs to create browser sources (after displaying a confirmation prompt to ensure it was by intention) [WizardCM]
Developers can add an embed to their web pages that let them pre-specify parameters that automatically get set in the source when it's dragged into OBS. See this link for more details: https://obsproject.com/tools/browser-drag-and-drop
Added T-bar to studio mode [cg2121]
Note that this will not work while using a Stinger transition or the "Cut" transition
Added support for the SRT protocol (https://en.wikipedia.org/wiki/Secure_Reliable_Transport) [boxerab]
This is available by choosing "Custom" under Stream settings > Service, then entering your srt:// path into the Server box.
Added a button grid mode to the scenes list, which can be toggled via right-clicking on the scenes list [Dillon]
Added ability to lock volume values of audio sources via their right-click context menu in the mixer [cg2121]
Added source icons to the source list that give a more visible indication of their function (can be disabled in the View menu) [cg2121]
Added support for cube LUT files in the LUT filter [jpark37]
Added an option to show all audio sources to advanced audio settings [exeldro]
Added an option to use percent rather than dB in advanced audio properties via right-clicking items in the window [cg2121]
Added a button to save replay buffer next to the replay buffer button (similar to the pause button on the recording button) [cg2121]
Added support for certain devices that can automatically rotate their camera output such as the Logitech StreamCam [Jim]
Added the ability to change the projector type to the projector's right-click context menu [cg2121]
Added the ability to copy/paste multiple selected sources [torresam]
Added an option to enable/disable BTTV and/or FFZ chat extensions when connecting your Twitch account in the stream section of settings [Rodney]
Added a system tray icon to show when the recording is paused [Programatic]
Added a "Custom Quantization Matrix" option to QSV encoder (available on Ice Lake or newer) [brittneysclark]
Added an option to toggle looping to the scroll filter [Dillon]
Added a "Fade to Black" option for quick transitions in studio mode [cg2121]
Added string specifiers to the Filename Formatting option in advanced settings which allows you to specify certain settings such as resolution and FPS to recording filenames [exeldro]
Added a hotkey to reset the stats window/panel [cg2121]
Added help icons when an property has a tooltip associated with it [WizardCM]
Added monitor names in monitor selection context menus [WizardCM]
Video settings now shows aspect ratio of canvas and output resolutions [cg2121]
Changes/Tweaks
Increased default size of color source to the size of the canvas [cg2121]
Increased default size of text in text sources [cg2121]
Increased the number of files you can open with the image slideshow at once [Jim]
Added various minor performance improvements [jpark37]
The mask filter will now reload the mask automatically if the mask file has been modified [omkelderman]
The browser source now uses a monospace font for the custom CSS property [WizardCM]
Redesigned Decklink output UI by combining the start and stop buttons and highlighting them when the output is active. [cg2121]
Removed the older deprecated NVENC encoder in advanced output mode to prevent confusion. You will now only see "NVENC (new)" (which we will eventually rename back to just "NVENC"). Rescaling is now supported on it (automatically falls back to the older implementation internally)
Bug Fixes
Fixed an issue where window capture could select an unintended window when opening its properties [Jim/Dillon]
Fixed browser source not loading files with a hash character in the path [Dillon]

Changes for v24.0.1 - v24.0.3

Fixed a startup crash on the 32bit version of OBS
Fixed an issue where audio monitoring on Windows would have a bit of unintended latency introduced by 24.0.2
Changes
Hardware accelerated decoding on the media source is now disabled by default rather than enabled by default. Some users use a ridiculous number of media sources, and turning on hardware accelerated decoding for every single one of them could cause some stability issues.
When running OBS as administrator, games will now be much less likely to cause lag to the video of OBS (we will eventually get this improvement working without requiring administrator, currently this does not work unless OBS is running as administrator)
Fixed an issue where media keys on your keyboard could trigger video/audio to stop/start playing in browser sources
Fixed an issue where part of the OBS output would be green when using OBS from a VM
Fixed an issue where stingers could sometimes cut off prematurely before they were finished
Fixed a freeze that could happen when using NVENC and changing the bitrate while in use while lookahead was enabled
Fixed a bug where OBS could sometimes stop recording due to lack of disk space despite having plenty of disk space
Improved the playback accuracy of media sources and stingers (this was the same issue that caused stingers to sometimes play back a bit erratically)

Changes for v24.0 - v24.0.1

Browser sources will now have their pre-24.0 audio behavior by default; to use OBS to control the browser source audio, users must now use the "Control Audio via OBS" option in the browser source properties. This change was made as a safety precaution because it changed user configurations compared with how the browser audio used to function, which confused some users.
Fixed an issue where certain cameras (particularly C920 cameras) would output with a lot of delay depending on the drivers installed
Fixed a crash on startup
Fixed a crash that would happen when closing the Mixer chat window

Changes for v23.2.1 - v24.0

New Features
Added the ability to pause while recording to allow seamless on-the-fly removal of video segments. This can only be used when not sharing an encoder with the stream. [Jim]
Added an option to automatically adjust bitrate when congestion occurs to advanced settings, which is an alternative to dropping frames (available in advanced settings). Note that this currently only works with RTMP, and severe congestion may cause increased delay to viewers. [Jim/pkv]
Added the ability to select multiple sources on the preview by box selection [Dillon]
Added the ability to create custom browser docks in the View -> Docks menu. This allows you to open extra dockable webpages whenever OBS opens [Jim]
Browser sources can now have their volume adjusted via the audio mixer, or have filters applied to them. Additionally, you can now change whether the browser source outputs to speakers or to stream only via the audio monitoring settings in advanced audio properties. [Osiris/pkv/Jim]
Added a script to pause recording when a specific scene is active [cg2121]
Added a "Hotkey Focus Behavior" option to advanced settings, which allows you to set whether hotkeys are disabled depending on whether you have the main window in focus or not [jb-alvarado/Jim]
Added an option to general settings to allow users to confirm when clicking the "Stop Recording" button [glikely]
Added channels widget for restream.io service integration [SoftwareArchitector]
Added the "Area" shader as a downscale shader in video settings [jpark37]
Added an "Enable Preview" button to the main window when the preview is disabled [cg2121]
Added (or rather fixed) hardware acceleration support for decoding media files when using the media source where applicable [Jim]
Tweaks/Fixes
Updated all dependencies on Windows (such as FFmpeg, x264, CEF) to their latest versions. Due to x264 being updated, there are various performance improvements for those using x264 for video encoding [Jim]
Made a number of optimizations and performance improvements [jpark37]
Made a number of performance improvements to QSV [brittneysclark]
Changed default recording format to mkv instead of flv [WizardCM]
Recording now automatically stop if there is less than 50 megabytes left of disk space available [cg2121]
Fixed a number of issues with Linux window capture [kkartaltepe]
Fixed the tray icon showing up on startup even when it was turned off [Jim]
Fixed a bug where encoders could lock up when an encode call fails [Jim]
Fixed an issue where projectors would have a gray background rather than a black background [Jim]
Fixed a bug where secondary Twitch/Mixer browser panels would stop appearing [Jim]
Fixed a freeze that could happen under rare circumstances when shutting down [Jim]
If no tracks are selected when recording in advanced output mode, it will now default to the same track being used for streaming [cg2121]

Changes for v24.0 RC4 - v24.0 RC5

Added various improvements and fixes for those who use screen readers with OBS
Fixed audio cutting in/out when using NVENC with the lookahead setting enabled while using dynamic bitrate

Changes for v24.0 RC2 - v24.0 RC3

Release Candidate 3 Fixes
Fixed a bug where browser widgets/docks would not shut down properly
Fixed an issue where if you had a lot of browsers in a scene at once, the browsers would stop rendering when you switch away and back to the scene they were in
Fixed a crash either on shutdown or when switching profiles that could occur when you had Twitch/Restream/Mixer integration browser widgets in use
Fixed a bug with the media source where it would not loop properly or would hiccup when hardware accelerated decoding was enabled
Fixed a bug with the media source where certain hardware decoders would output corrupted video
Fixed a bug where pause would desynchronize audio/video the more often it was used
Fixed a bug where pausing could cause a crash or freeze when pausing/unpausing over and over too quickly
Browser docks now fully shutdown when hidden (prevents playback of any video/audio that may have been playing by browser)
Added an option to browser sources, "Reroute audio through OBS", which is enabled by default. This allows the user to turn off the new browser audio handling if they need to for whatever reason (usually only useful when you need to monitor with a different device than what OBS is set to monitor with)
Release Candidate 2 Fixes
Fixed a bug where browser source audio would cut out with certain stream notifications
Fixed a bug where browser sources would sometimes stop rendering
Fixed an issue where x264 would spam the log every time the bitrate changed when dynamic bitrate was activated

Fixed a bug where background-removing cameras would have a hall of mirrors effect
23.2 New Features/Improvements
Made a number of major internal improvements to the macOS browser source, eliminating many mac-related crashes that it would cause when browser sources were in use on macOS. This also fixes the issue of the program having an initial startup delay where the everything appeared blank. (Author note: I managed to get browser panels functioning, but they still have some issues, so service integration is still not yet available on macOS)
Added the ability to preview transitions in the properties of a transition via a new Preview button
Added an estimate to remaining available recording time according to available disk space
Added luma key video effect filter
Added the ability to set the exact desired dB volume value of sources in the advanced audio properties, replacing the percentage value

Changes for v23.1 - v23.2 RC 1

New Features/Improvements
Made a number of major internal improvements to the macOS browser source, eliminating many mac-related crashes that it would cause when browser sources were in use on macOS. This also fixes the issue of the program having an initial startup delay where the everything appeared blank. (Author note: I managed to get browser panels functioning, but they still have some issues, so service integration is still not yet available on macOS)
Added the ability to preview transitions in the properties of a transition via a new Preview button
Added an estimate to remaining available recording time according to available disk space
Added luma key video effect filter
Added the ability to set the exact desired dB volume value of sources in the advanced audio properties, replacing the percentage value
Added the ability to center items vertically/horizontally in the transform menus
Added a hotkey to toggle the preview
Added the ability to output the preview rather than program to a decklink device when in studio mode
Added the ability to copy and paste filters to/from scenes in addition to sources
Added the ability to manually set the network buffer size to the Media source when used in URL mode
Added the top patrons list to the about dialog in the help menu
The sources list box in the bottom-center of the main window now displays a message when there are no sources in the current scene, making it easier for first-time users to understand that they need to add sources

Changes for v23.0.2 - v23.1

New Features/Improvements
Added optional Twitch activity feed panel when account is connected to OBS (hidden by default)
Added Restream.io account integration
Added option to select color range to Linux video device source
Added ability to copy and paste filters from the mixer
Added preview/program labels to studio mode
Added new settings icons
Added a checkbox for bandwidth test mode in settings when using Twitch account integration
Added 25/50 PAL framerate values in video settings
Added "Area" scale filtering for sources as an alternative to point scaling. May preserve more detail on retro games
Added the ability to select video / audio connectors on the Decklink source from inside OBS
Added the ability to swap Front Center and Low frequency effects channel on the Decklink source
Improved the attack/release processing of the expander audio filter
Bug Fixes/Tweaks
Reverted 23.0 changes to slideshow, and instead introduced a 250 megabyte memory limit to image slideshow so people can't accidentally exhaust their memory by loading countless images from a folder. This fixes an issue where large image counts would cause increased CPU usage and rendering lag when transitioning images, or when switching scenes in some cases.
Removed the close buttons from primary docks (scenes, sources, transitions, mixer, controls). These docks can still be hidden, but now must be explicitly hidden with the view menu instead. This change does not apply to secondary docks, such as chat, stream information, or stats.
On Linux, the tray now uses icons from the system theme
Fixed a bug when upmixing from mono to stereo would cause the volume to be quieter
Fixed a bug where NVENC wouldn't show up for the NVIDIA Quadro P5000
Fixed another case where the last frame of an NVENC stream/recording could show up as the first frame in a subsequent stream/recording in the same running session
Fixed another case where output could be green for certain devices
Fixed a crash that could happen if you clicked settings too quickly after starting up with streaming account integration, or if you exit the program too quickly

OBS Studio 23.0
You can now support OBS development on Patreon and Open Collective. Read our announcement blog post for more details.
Service Integration (Windows)
Added the ability to optionally connect your account to Twitch or Mixer from within OBS (with more services in the works). When your account is connected, you do not have to enter in a stream key, and gain access to special features related to that service, such as a chat panel or stream configuration/statistics panels.
Twitch integration: Added Twitch chat panel (with BTTV/FFZ support), the Twitch "Stream Information" dashboard panel allowing you to change your stream title/game/etc from within OBS, and the Twitch "Stream Stats" dashboard panel which shows statistics such as viewer count (Stream Stats is hidden by default, you can unhide it in the View menu -> Docks submenu).
Mixer integration: Added Mixer chat panel
Panels such as chat panels used with services are dockable; you can dock/undock the windows to customize how you want them to be placed when using OBS.
YouTube, Facebook, and more services are still in the works; more to come soon.
Service integration is currently only available on Windows for now, though Linux and Mac support is planned for a later date.
NVENC and Encoding Improvements (Windows)
A new implementation of NVENC has been added which has improved performance, reducing system and resource impact. To enable, go to Settings, Output Tab, and in Encoder select Hardware (NVENC) New. Note that the new implementation is not available on Windows 7 due to limitations in the operating system; the old implementation will be used instead in that case.
Added new features to the new NVENC implementation:
Psycho-visual Tuning: Enables encoder settings that optimize the use of bitrate for increased perceived visual quality, especially in situations with high motion, at the cost of increased GPU utilization. This increases subjective image quality. Qualitative measurements like PSNR may score lower but video may appear better to human viewers.
Look-ahead: Enables dynamic B-frames. If disabled, the encoder will always use the number of B-frames specified in the 'Max B-frames' setting. If enabled, it will increase visual quality by only using however many B-frames are necessary, up to the maximum, at the cost of increased GPU utilization.
General Changes
Added a Limiter audio filter.
Added an Expander audio filter.
Added VAAPI video encoder on Linux.
Added batch remuxing support to the Remux Recordings dialog.
Added an option to automatically remux recordings to MP4 in Advanced settings.
Added a Decklink output tool to the tools menu. This allows you to output OBS to a Decklink device.
Added an optional Stats dock. This dock is disabled by default; you can enable this dock in the View menu -> Docks submenu.
Added multi-track audio support to FFmpeg output in advanced output settings.
Added an About dialog to the Help menu.
Added a filter (search) option to the Hotkeys section of the settings window.
Added a fourth Mic/Auxiliary audio option in Audio settings.
Added stereo balancing (panning) to the Advanced Audio Properties dialog.
Added an option to change the OBS base/output resolution to the size of a source in the right-click context menu of the source. Only works when no outputs are active.
Added a "deactivate when not showing" option to the Decklink source.
Added an Invert Polarity audio filter.
Added an F2 shortcut to rename sources or scenes when selected.
Added VLC source support to the Instant Replay script.
Added a "What's New" dialog that may pop up on startup in the case of announcements or important news
Fixed a bug where screen reader tools for the visually impaired would not read out the items in the source list box in the main window when selected.
Fixed a bug where fullscreen projectors would always be on top despite that setting being unchecked.
Fixed an issue on windows where window capture would use an abnormal amount of CPU usage when its target window was not available
Fixed a number of race conditions and minor memory leaks, improving overall program stability.
When your mouse cursor is hovering over a source in the preview or in the source list, a light rectangle will show up around it indicating that it can be selected.
When a source is dragged outside of the preview area, there is a new visualization for the unseen area of that source while selected.
Simplified and improved the user experience of the "Stream" page of both the settings and auto-configuration windows.
The source selection rectangle has been improved.
The slideshow source now only loads a maximum of 15 images at a time, and dynamically loads images beyond that count as they cycle. This was done to prevent people who put countless files in the slideshow source from running out of memory.
When in studio mode, you can no longer transition if you're already in the middle of a transition.
Removed a number of internal/uncapturable Microsoft program windows from the game/window capture window lists.
Increased the Instant Replay script retry interval.
Docks are now unlocked by default. You can lock/unlock docks in the View menu -> Docks submenu.

Changes for v23.0 RC 1 - v23.0 RC 2

Fixed a bug where there was a chance for a crash on shutdown
Fixed a crash when starting certain types of encoders before starting the new NVENC encoder

Psycho-Visual Tuning is now enabled by default as a test for RC2
Increased the default size of the Twitch "Stream Stats" panel so that affiliates/partners can see their subscriber count/points
New NVENC settings are no longer exposed to the older version of NVENC (for now)
Added a missing text string for the Remux recordings dialog
The slideshow source now will update when you press OK or Apply on its properties rather than when you modify any setting. This prevents the source from reloading its images on any change.
Removed unused 'help' icons from from the title bar of many various dialogs, both new and old
