Are they? zlib is still being developed; the last commit was two days
ago.
they have been revived as -ng projects. In Ubuntu, rather than doing
a mini transition and potentially causing things to break, we were
wondering if anyone has thought of doing the transition to the -ng
projects. They are completely API/ABI compatible and are essentially
drop-in replacements so long as it's done wholesale.
I think there has been work in this direction, but zlib-ng compresses
slightly differently from zlib. This shouldn't be an issue, but in
practice I've seen different projects hardcode the results of data
compression especially in tests, which leads to test failures.
I'm not opposed to migrating to the -ng variant, even though ideally I'd
like to see the two projects converge back into a single zlib library.
In any case, for this particular issue, can't Blender (or OpenColorIO)
depend on minizip-ng, with the latter co-existing with the non-ng
variant?
Bye!
