[Buildbot-devel] SQLAlchemy version check fragile? Running buildbot master test suite on Ubuntu 14.04 beta 2

[Vasily]

That's about what was in my mind... but you put it into words better.
E.g. in <= 0.8.9 we use SQLAlchemy, and in 0.8.10 :) or 0.9 - whichever
comes first - we'll start using Alembic.

Not a big deal to install an intermediate version to get your DB migrated
correctly IMHO.

Thanks,
Vasily
