👓 What did you see?

Given an unreleased project, I can't use polyglot-release to release it:

mpkorstanje@Nyx:~/Projects/cucumber/polyglot-release$ ./polyglot-release 0.9.0
Error: There are no released versions in the changelog yet

Followed by git tag v0.0.0

Ran into the same issue on cucumber-ruby when releasing v9. We made the CHANGELOG.old.md but the new changelog still needed a version (Essentially the same issue you commented on).

Our workaround was to include the last 2 versions manually formatted in the new changelog, then the rest got canned
