OBS Studio 22.0.1 hotfix:

Fixed a bug where the browser source wouldn't read local files properly

v22.0 general changes:

Major improvements to the browser source

Added hardware acceleration to the browser source on Windows for greatly improved performance, reduced resources, and allowing advanced rendering functionality such as WebGL. This reduces CPU usage, reduces RAM usage, and even reduces GPU usage. This option is enabled by default; it can be disabled in the advanced section of settings if needed if there are any unexpected issues.
Updated to Chromium version 68
Refactored the entire plugin and pruned approximately 13,000 lines of code (very satisfying for me in particular)
The browser source now has accurate frame synchronization on Windows
Fixed all memory leaks of the browser source
Added the ability to use web browsers as widgets (which isn't currently exposed much, but will allow a lot more custom functionality later)

Added source grouping, allowing the ability to group multiple sources together as a single transformable group

To add a group, you can either select a few sources and then right-click and choose "Group Selected Items", or you can create an empty group in the Add menu
You can seamlessly drag and drop items in and out of groups
You can ungroup a group without affecting the group in other scenes by right-clicking the group and choosing "Ungroup"
Groups show their list of sources as a sub-list within the main scene list, which can be collapsed and hidden if desired
Groups can be referenced (shared) between multiple scenes like any other source
Groups can have their own effect filters applied to them

Added the ability to set a custom background color to items within the source list to color-code them for improved organization

To set the item's background color, right-click the source item within the source list, and go to "Set Color"
You can use a preset selection of colors within the menu, you can choose a custom color, or you can reset it to default
Added a "Vertical Layout" option to the mixer's right-click context menu to make the mixer display vertically rather than horizontally (#1257)
The multiview can now be configured to show up to 24 scenes at once in general settings if desired (#1260)
Added an option to audio settings to allow the user to change the audio meter type: "Sample Peak" and "True Peak" (#1189)
Added secure streaming (RTMPS) support for services that support it, such as Facebook (#1360)
It is now possible to use more than one Intel QSV encoder at once (#1341)
It is now possible to use alt-cropping even on sources that are set to a bounding box transform. This fixes the issue where, for example, alt-cropping would not work after you pressed Ctrl-F on a source. Note that in that case, the rectangle's size will not change, but the contents will realign to the rectangle. (01ac60c)
Windowed projectors are now saved and loaded on shutdown/startup (#1195)
Audio sources within the mixer now always displayed alphabetically (#1242)
Significantly reduced GPU usage when the program is idle (I.E. when the program is not streaming or recording) [full release notes]
