Hi Ixen,
the updatecheck seems to check against the wrong build number.
The latest stable is 1.45.1048.0 from 2020-12-24, but it wants to have 1.46.1048.0 from 2020-12-24 in stable or rc channel.
See picture.
It seems like somewhere in the release process version was not bumped to 1.46. For now I've implemented a workaround that does not need creating a new build.
Thanks, updatecheck now reports i have the latest version installed!
