MarsSeed [1] filed a request to merge msquic-prerelease [2] into msquic-git [3]: It's pointless to keep a prerelease package, since this is for v1.9.0 from October 2022. The last stable release, v2.2.4 is from October 2023, and is therefore 1 year newer than the last prerelease commit. Upstream seems to no longer create prerelease tags. People who wish to test-drive the latest development code should install msquic-git.
