Installing Swift 5.7.1 from Swift.org - Download Swift results in an installation that reports version 5.7.0 in the Settings app and in Programs and Features. Installing 5.6.3 and 5.6.2 report version 5.6.1, as well.
This is seen as a problem for publishing a manifest for Swift 5.7.1 on winget:
Looks as if the publisher forgot to update the DisplayVersion ARP Entry. It should be 5.7.1 instead of 5.7.0
Yeah, the ARP is incorrect as there is a manual step for the version information handling. Patches to help improve that and automate it to ensure that this does not accidentally drift is absolutely welcome!
