We have recently changed the artifact name in the pom of one of our projects, and since then Gren doesn't seem to find new released versions to generate release notes when running 'gren release' (it only finds the previous two versions before the name change occurred - which have already had release notes generated!).

The tag created by maven release:prepare is visible in Github, and release notes can be added manually which I assume would make them into a Release as far as Github is concerned?

Incidentally, running 'gren release —tags=all' did generate notes for all versions, including the new ones since the name change.

How does gren identify the last two releases in github to generate the last two release notes?

Thanks!
