Detailed Description
SDL 2 feature development ended some time ago with efforts being focused on SDL 3. However, many older games still use SDL 2 and cannot change to SDL 3. In order to continue to support SDL 2 games in the modern world, let's replace SDL 2 with sdl2-compat, which uses SDL 3.
Feedback
Benefit to Fedora
Switching SDL 2 powered games to use sdl2-compat ensures that SDL-based applications continue to use the actively developed codebase.
Scope
- Proposal owners:
- Package libsdl2-compat (RH#2316576)
- Retire
SDL2 - Do the same thing for the mingw counterparts
- Other developers:
- Release engineering: #12485
- Policies and guidelines: N/A (not needed for this Change)
- Trademark approval: N/A (not needed for this Change)
- Alignment with the Fedora Strategy: N/A (not needed for this Change)
Upgrade/compatibility impact
The SDL2 package would be transparently upgraded to libsdl2-compat package and games using it should just transparently start using SDL 3.0.
Early Testing (Optional)
Do you require 'QA Blueprint' support? Y/N
How To Test
1. Swap SDL2 for sdl2-compat: dnf swap SDL2 sdl2-compat
2. Run something that uses SDL 2 like 
supertuxkart
User Experience
There shouldn't be a noticeable user impact, other than possibly a smoother experience because applications are using SDL 3.0.
Dependencies
Contingency Plan
- Contingency mechanism: (What to do? Who will do it?) N/A (not a System Wide Change)
- Contingency deadline: N/A (not a System Wide Change)
- Blocks release? N/A (not a System Wide Change), Yes/No

Release Notes
Games that use SDL 2 will now transparently use SDL 3 through the sdl2-compat package. This makes it so applications that historically used SDL 2 now use SDL 3.
