These are not stable releases of software packages!

Users looking for stable releases should look here.

Note that snapshots are only generated when there has been a commit to the corresponding branch in the Git repository. This may be less than once a day!

Tarballs are made from the Git main nightly at approximately 9pm US Indiana time.
