+v0.2.2
+------
+- Fixes:
+ - Fixed corrupted text rendering when a vessel loads during a scene change.
+
 v0.2.1
 ------
-- Changes
+- Changes:
  - Pressing enter in the text entry window now types a newline.
-- Fixes
+- Fixes:
  - Renamed font assetbundle. The old extension was causing the game to try to load it twice on Windows due to legacy compatability features.
  - Fixed text rendering on DirectX resulting in black boxes by using ARGB32 instead of RG16 for the render texture in DirectX.
