This version check implementation has the same issue as the one in the UI. If a "dev" version from a commit is used, it complains. Is this also fixed? Or expected?

[anbraten]

For development versions it will skip the check. For pre-releases / next versions it will show you the hint to update to the latest stable, that should be okay however, I guess.

Thanks 👍

@anbraten two questions about the version:

1. What happens with next- version?
2. Why don't we reuse https://woodpecker-ci.org/version.json? This would allow to also suggest RCs if you're currently on a RC

[xoxys]

Should answer "What happens with next- version?"

For pre-releases next versions it will show you the hint to update to the latest stable

[qwerty287]

Ah sorry, I missed the word "next" there and thought you mean RCs...
Still I think it would be better to properly support next and show next updates - shouldn't be that hard using version.json.

[anbraten]

Adjusted the code to use our version.json file. We could potentially run into a 404 error as we don't know if the binary is actually uploaded (yet) if we see a new version, but I think that shouldn't be an issue and the user will simply get an error in that case.

Deployment of preview was successful: https://woodpecker-ci-woodpecker-pr-3518.surge.sh

code looks good, untested

Fixed the wrong url string in the code and added a test. Also tested it again. Seems to work now.

Desc is wrong now.
