Unable to create a Release with non-semver versioning

[calverp]

Severity

Blocking any customers using non-semver versioning, 1 known instance impacted

Version

2026.2.1361

Latest Version

I could reproduce the problem in the latest build

What happened?

When trying to create a new release with non-semver versioning ("prod-271c680") it is blocked due to the auto-increment not being able to run.

The auto-increment shouldn't need to run as a version is being manually supplied

Reproduction

• Create a new release
• Input a non-semver version e.g. "prod-271c680"
• Hit Save

Error and Stacktrace

The version template for project 'Misc' generated 'prod-271c6803'. Versions that do not start with a numeric component cannot be auto-incremented on future releases. Check the template does not include variables that resolve to non-numeric text.

Workaround

If you create a the release with a semver compliant version, you can then edit the release afterwards to have your desired non-semver version number.
