- Backends: DX9: Fix to support colored glyphs, using newly introduced 'TexPixelsUseColors' info. (#3844)
- Examples: Reworked setup of clear color to be compatible with transparent values.
- CI: Use a dedicated "scheduled" workflow to trigger scheduled builds. Forks may disable this workflow if
scheduled builds builds are not required. [@rokups]
