I think the chart version here 9.10.01 is a typo and could cause issues due to not being a valid SemVer. This should probably be resolved before updating the gh-pages branch with the chart releases, I'm happy to open a PR to raise this to 9.10.2.

[gjtempleton]

@stevehipwell Good catch, you're 100% correct.

If you could raise that PR that would be great. I've stuck a hold on the PR to update the index.yaml for now.
I'll have a look into why the chart version not being SemVer didn't lead to a failed CI run.

[MarcusNoble]

Ah yes! Good catch indeed. Looks like I made a typo when handling the merge conflict.

I've added PR #4183.

[gjtempleton]

After a bit of digging, found why this slipped through linting. It seems both chart-testing and helm's semver functionalities use https://github.com/Masterminds/semver#parsing-semantic-versions and use the NewVersion rather than StrictNewVersion functionality.

With a bit of testing in a cluster this non-compliant version will still successfully install, as it seems all of the code dealing with SemVer handles these versions in the same way.

[stevehipwell]

That's my understanding too, but other tools using StrictNewVersion will error. There is also a precedence for Helm itself to start erroring as it does from v3 with versions not even close to SemVer (the official Flink repo has this issue).
