Cannot get GitVersion 6.1 to work with prerelease label from git tag

[ThomasHoevel]

So far, we are using GitVersion 5.12.0 and the VS build task.
When we start working on version e.g. 6.2.0, we tag the develop branch with “v6.2.0”. Then for our feature branches, we get NuGet package names like “6.2.0-dev-fix-unit-tests.242”.
When it’s time to publish 6.2.0-preview-1, we create a release branch and tag it with “v6.2.0-preview-1”. This leads to NuGet packages with the version “6.2.0-preview-1”.

Now we tried GitVersion 6.1 and could not get it to work having the “preview-1” tag taken automatically from the git tag of the current commit.
Can anyone give us a hint on how to get the old 5.x behavior with version 6.1 or 6.2? Thanks in advance.

This is not possible. In the new version (6.x) of GitVersion, pre-release tags are only considered when they matching with the label property. You can change the behavior and set the label branch property (and the fallback property on the root) to null (by just define label: in yaml). But this has the conseqence that your branch name will be not used regulary as pre-release label.

Happy Branching!
