Description
In short, by using the new PC/layout script against older versions, a rename that used to be performed at build time was skipped. As a result, the republished 3.11 and 3.12 packages have a non-functional venv module on Windows.
Once the script is fixed (and tested more thoroughly), I'll repackage and republish the 3.11 and 3.12 releases. This will update their hashes, but should update the feed as well so that it still all matches. That's what beta is for I guess.
The fix won't need to be backported, because repackaging uses the script from main (which was fundamentally the root cause). I'll do a full diff between the old and current version of the scripts to see if any other changes slipped through, but I don't think there was anything that wasn't purely additive.
FYI @pablogsal and @Yhg1s as RMs for the affected releases. Nothing for you to worry about, though.
