Looking at Install gitea on Linux | Snap Store the latest stable version is 1.19.0, while 1.19.1 has been out since 2 weeks.
Will 1.19.1 not be released as snap or is it not a stable release?
According to one of the maintainers in the Discord,
It needs to be promoted from the experimental channel, but there are several issues with it and when it upgrades for cloud providers one-click images. So that step hasn’t been taken.
