 ### Detailed list of changes
 
+* Added support for Lottie animations (vector graphics), fully configurable as a theme extra
 * Added scraper support for displaying the returned platform if it does not match the game platform, or if multiple platforms are defined for the system
 * Set the option "Scrape actual folders" as enabled by default and moved it higher up in the scraper options menu
-* On Windows, moved all dependencies in-tree to the "external" directory to greatly simplify the build environment
+* Added a color model conversion shader for converting from BGRA to RGBA
+* Added renderer support for supplying a separate format than internalFormat when creating textures (although not really supported by the OpenGL standard)
+* Added the rlottie library as a Git subtree
+* On Windows all dependencies were moved in-tree to the "external" directory to greatly simplify the build environment
+* Large refactoring to improve thread safety and improve singleton pattern usage
 * Removed the deprecated VideoVlcComponent
 
 ### Bug fixes
 
+* During some menu operations that reloaded the gamelist view, the cached background would sometimes miss some elements as they were not rendered in time
 * The ScummVM platform entry was missing for TheGamesDB which resulted in very inaccurate scraper searches
 * During multi-scraping the busy indicator was not displayed after a result was acquired but before the thumbnail was completely downloaded

+There are a number of compiler warnings for the bundled rlottie library when building with MSVC. Unfortunately these need to be resolved upstream, but everything should still work fine so the warnings can be ignored for now.
 
 Unfortunately nmake does not support parallel compiles so it's very slow. There are third party solutions to get multi-core building working with MSVC, but I've not investigated this in depth.

+    - If only one axis is specified (and the other is zero), the other will be automatically calculated in accordance with the animation's aspect ratio. Note that this is sometimes not entirely accurate as some animations contain invalid size information.
+* `origin` - type: NORMALIZED_PAIR.
+    - Where on the animation `pos` refers to.  For example, an origin of `0.5 0.5` and a `pos` of `0.5 0.5` would place the animation exactly in the middle of the screen.  If the "POSITION" and "SIZE" attributes are themeable, "ORIGIN" is implied.
+* `rotation` - type: FLOAT.

+    - The direction that the animation should be played. Valid values are `normal` (forwards), `reverse` (backwards), `alternate` (bouncing forwards/backwards) and `alternateReverse` (bouncing forwards/backwards but starting with playing backwards). Default is `normal`.
+* `keepAspectRatio` - type: BOOLEAN.
+    - If true, aspect ratio will be preserved. If false, animation will stretch to the defined size. Note that this is incompatible with only defining one of the axes for the `size` element. Default is `true`.
