Looks good.
I have two questions:

1. The logger does output only text. If act is started with '--json' it should respect that. Otherwise the log would not be parsable
2. Why is the go-git patch by ZauberNerd removed?

[cplee]

Good catch @KnisterPeter . I updated to honor the --json for log format. Also reverted the change to go.mod (I was having issues with that patch and wasn't sure it was still needed?)

[KnisterPeter]

👍

[KnisterPeter]

We should check with @ZauberNerd.
What where the issues?

[cplee]

It was looking for tag v5.4.3 in his fork, which didn't exist

[ChristopherHX]

Is it expected behavior to always show new version is available for source builds without an explicit version?
Maybe only check for updates if a version is provided to act?

[mergify]

@cplee this pull request has failed checks 🛠

[cplee]

@ChristopherHX - updated to keep the source version aligned with release version. This will avoid alerting on new versions if built from source...unless there is in fact a new version available. Fixed #1069 and #1555 too...

[ZauberNerd]

Oh, I rebased my PR go-git/go-git#485 last month, that's probably why it couldn't find the tag anymore.

[ChristopherHX]

Looks good to me
