Until now we have not had a formal process for selecting a release manager and it happened ad-hoc. Our release process has been evolving continuously and the interest to be a release manager has been growing. For being the release manager of Reference Application 2.5 the interest has grown enough for us to think about a selection process and criteria. Kudos to the community!
I have created a basic process/criteria in our release process page. Anyone with an input for this please respond to this talk post for it to make it as transparent as possible for selecting a Release Manager for each release.
