50.08 is the current version, 0.47.05 is from 2021-01-28. note that the leading 0 was dropped.
Here comes 50.10 already. Works good out of the box but may we have it in main tree also?:)
Haven't done any testing beyond getting the game to launch (v50.11), but it looks like the update to SDL 2 means media-libs/sdl2-image[png] should replace media-libs/sdl-image[png], not sure about the other deps.
