* Fixed text/color sources not being backward compatible with older versions
* Fixed text/color sources from older versions not showing up in "Add Existing" when adding a source

* Fixed a bug where some Vulkan-based games would have red and blue inverted when capturing with game capture
* Fixed a bug where restarting a media source with a hotkey would cause it to repeat multiple times

Release Candidate 2 Fixes
-------------------------
* Fixed a bug when importing streamlabs scene collections with repeated names
* Fixed a crash that would happen when using the new capture method in window capture and running OBS as admin or when using an older version of Windows 10
* Fixed a bug where the new capture method in window capture was selectable even when it was unavailable, such as when running on older Windows 10 versions
* Fixed a bug where SRT output wasn't working properly

New Features
------------
* Added the ability to capture Vulkan-based games with game capture.  Big thanks to Ubisoft for the help!  [Littlematth/jpark37/Jim]

  * Note: Currently may not work with Rainbow 6 Siege until the game is updated to support the new hook

* 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

* Implemented browser plugin on Linux [bazukas/cg2121]
* 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://wizardcm.github.io/OBS-Drag-Demo/

* 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 help icons when an property has a tooltip associated with it [WizardCM]
* Added monitor names in monitor selection context menus [WizardCM]
