ncu --upgrade -t minor --pre 0

Updates the package supabase to version 1.163.6 which is tagged "beta"

Shouldnt it update to 1.163.2 which is tagged "latest"?

Hi, thanks for reporting. You're right, this is somewhat confusing behavior.

--pre includes/exludes semver versions that end in a prerelease version part, e.g. -alpha.0, -beta.5, -rc.2. 1.163.6 is not a prerelease version, but a patch. I'm not sure why supabase is publishing patches to the beta tag. This seems a bit unconventional to me. To be valid semver, 1.163.6 must be a non-breaking change from 1.163.2.

There is furthermore a functional reason why npm-check-updates cannot exclude normal versions published to the beta tag when using -t minor. If supabase published 2.0.0 to the beta tag, then there would be no way to tell that 1.163.6 was a beta, because the npm registry does not keep a tag history. This would result in ncu -t minor --pre 0 recommending different versions depending on when the command was executed and what was published to beta, even if none of the 1.x versions have changed.

In light of this, I would recommend using -t minor or --pre 0, but not both for supabase.
