OBS Studio 27.1

What's new in this version:

New Features and Additions:
- Added YouTube integration
- Allows the ability to connect your YouTube account without using a stream key
- Adds various features when setting up your stream that allows you to set settings for each stream: your stream title, description, privacy settings, scheduling streams, and more
- YouTube streams are created and managed via a new “Manage Broadcast” button next to “Start Streaming”
- Also features a chat dock for public and unlisted broadcasts (currently read-only)
- Bandwidth testing is now supported in the Auto-Configuration wizard when logged in
- Special thanks to the developers at YouTube for working with us directly on the initial implementation of this feature and helping to make it a reality
- Added an 18-scene multiview option
- Added a “Mask Only” option to the stinger track matte
- Added a feature to browser sources to allow limited control over OBS, which must be explicitly granted by the user
- Added an option to draw safe areas in the preview (same as the safe areas in the multiview)

Tweaks:
- Added performance fixes for Windows 11 and Windows 10 Insider builds
- Names for displays on macOS Display capture are now human readable names [Developer-Ecosystem-Engineering]
- Auto-Remux now works with Replay Buffer
- Optimized the media source, reducing unnecessary CPU usage
- The missing files dialog will now detect missing files for stingers as well
- Remove “Enter Fullscreen” from the menu on macOS because macOS already has a builtin fullscreen mode interface option
- Sources that are invisible/hidden will now have their text dimmed as well in the source list
- Added a “Missing Files Check” menu item to the “Scene Collections” menu
- Added source icons to the source toolbar
- Image sources that use gif files now will animate in preview when using studio mode
- Enabled Alpha option in the Freetype 2 Text Source’s Font dialog
- Added the ability to disable the Missing Files dialog using a startup flag
- Added Ctrl+R on Linux and Cmd+R on macOS to reload browser panels
- Re-enabled drag & drop for scenes & sources on Linux
- Minor UI improvements to various areas, including Source Toolbar, Transform dialog and more
- Improved internal behaviour in the game capture source to avoid unnecessary re-hooking
- Wayland capture sources are now available without having to pass custom parameters to OBS from the command line

Fixed:
- a bug on Wayland on Linux where the cursor would capture slightly mispositioned
- a bug with Dynamic Bitrate that would cause it to malfunction when used with hardware encoders [R1CH]
- a bug on Wayland where capture methods (ie window/desktop) that weren’t fully supported would appear anyway
- a variety of colour-related bugs in window capture and browser source
- a bug where track matte stingers would flash previous frames sometimes
- an issue where the projectors would list incorrect resolutions for DPI-scaled monitors
- a crash on exit that could occur when using 3rd party plugins that hold references to sources with audio monitoring enabled
- a bug where the Game Capture source would occasionally still capture overlays with the “Capture third-party overlays” option disabled
- a bug where keyboard interaction did not work correctly on macOS
- a bug where the replay buffer could crash when plugins interact with it
- an issue where the mask/blend filter looked incorrect on version 27
- a bug where deleting a scene that’s used as a source wouldn’t Undo/Redo properly
- a bug where the Auto-Remux would pop up blank sometimes
- a bug where performing a redo for creating sources would cause sources to be created in the wrong scene
- the “Deactivate when not showing” option in the Decklink source not working properly
- a bug where themes were unable to use previously defined palette variables
- log viewer taking up unnecessary extra memory when closed
- a crash that could occur when exiting OBS with decklink output active
- an issue where saving screenshots or the replay buffer would fail if the output filename format contained a directory path
- a crash that could occur when a connection was dropped during the Auto-Configuration Wizard’s bandwidth-testing stage
- Disabled "Network Optimizations" when using RTMPS because of incompatibility
- an issue where setting a zero second auto reconnect delay would cause OBS to stop responding if disconnected
