Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

And that links to https://www.7-zip.org/sdk.html , in the download there see the DOC folder for documentation? I really can't figure out how that somehow 'sends you back to python's lzma'...

PSA: zlib v1.2.12 is kinda broken... (breaks bunch of stuff including Minecraft)
See https://github.com/madler/zlib/issues/613 and https://bugs.archlinux.org/task/74371
- Did GLIBC 2.35 break xz-java?

Re: Zlib memory corruption on deflate (i.e. compress)
This seems to be a minor bug, in that it is only triggered using unusual (and rather unlikely) deflate parameters.
But, looking into this bug, I was sort-of interested to see how it was handled. The change log for 1.2.12 (2022-03-27) indicates the issue was resolved ("Fix a bug that can crash deflate on some input when using Z_FIXED"). Yet, in what seems to be the canonical Zlib repository (https://github.com/madler/zlib), I was unable to find a corresponding commit.
None of commits this year (7, so not too hard to review) seem to be particularity meaningful changes, and in particular yesterday's 'zlib 1.2.12' commit seems to only consist of version/copyright updates.
So, does anyone have any idea where to find the commits related to the change log entry? (Note that I'm not disputing the issue is actually fixed, I'm just trying to improve my Github reading skills...)
