Most msys2 environments are kept here only temporarily until
newer versions replace them. Only such environment versions that
are used for an actual freeciv release are permanently kept.

Msys2 environment versions used for freeciv releases follow.
The environment version for the release is also documented
in the README.msys2 document within the release.
