If there are tags (or branches) to indicate when the release is done, then a stable branch is ok with me.  I just want a way to get to a release somehow.  (Not that I've had to debug an issue in asdf.  But if I did, I want to be able to extract various releases for testing.) 

Quick response: there is always a current release branch. In addition, each release is tagged with its version number, so at any time one can recover any previous release.
