I think that definition *is* the problem, actually.  To me, "beta" means
"trial software, please test, but final product will be very similar to
what you see here".  What we need to convey at this point is what you
said, but I think a better word for that is "alpha".  There may be more
mobility in there than in a beta, in users's perception, which is the
right impression we want to convey.

Another point is that historically, once we've released a beta, we're
pretty reluctant to bump catversion.  We're not ready for that at this
stage, which is one criteria that suggests to me that we're not ready
for beta.

So I think the right thing to do at this point is to get an alpha out,
shortly after releasing upcoming minors.

OK, I can get behind that.

My only additional point is that it is a good idea to release an Alpha every time, not just this release.

And if its called Alpha, lets release it immediately. We can allow Alpha1, Alpha2 as needed, plus we allow catversion and file format changes between Alpha versions.

Proposed definitions

Alpha: This is trial software please actively test and report bugs. Your feedback is sought on usability and performance, which may result in changes to the features included here. Not all known issues have been resolved but work continues on resolving them. Multiple Alpha versions may be released before we move to Beta. We reserve the right to change internal API definitions, file formats and increment the catalog version between Alpha versions and Beta, so we do not guarantee and easy upgrade path from this version to later versions of this release.

Beta: This is trial software please actively test and report bugs and performance issues. Multiple Beta versions may be released before we move to Release Candidate. We will attempt to maintain APIs, file formats and catversions.
