What happened to SDL_sound?

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?

SDL_sound was always my personal project and not an official SDL satellite library, so that Mercurial repo is still the primary development location.

I should probably move it to GitHub (to my account, if not libsdl-org’s).
