I was looking through for replacements or upgrades of things to switch from SDL1 to SDL2, and I noticed the odd lack of replacement for SDL_sound.
At least on GitHub, I don’t see SDL_sound in the libsdl-org
GitHub organization.
I do see the Mercurial repository with the last commit three weeks ago: icculus/SDL_sound: Summary
Is this still being developed or at least planned to migrate to GitHub?
