I'm good with every 6 months, or annually, depending on what we find works
well. The important thing we can agree on is to start doing regular
time-based releases.

I forgot to mention one other thing: we should leave open the possibility
of breaking Java API changes. We intentionally did not do that in 2.5, and
I think in the end that policy was too strict: in a number of cases, we
could not fix resource leaks and related problems. We should minimize such
changes, however.

I'm glad you raised this potential problem. On the one hand, we have a lot
of bugs/missing features in zxJDBC that none of us feel comfortable
tackling because of the lack of test coverage. On the other, this scenario
could really derail the 2.7.0 rollout. This is especially true when we
consider that zxJDBC has proven to be stable for what it does, given the
underlying JDBC stability. And JyJDBC is easily installable by people who
needs its features.

So deprecating zxJDBC for now sounds like the best path. If we get more
experience with these possible problems, we can replace in a future 2.7.x,
where x > 0. And we will certainly remove zxJDBC in favor of JyJDBC for 3.5.

Thanks, this is why we triage! :)
