I expect Kevin et al can comment on any policies, but as far as know
there is nothing prohibiting database content or schema changes in
point releases. That said, it seems that the only schema change during
the 3.8 series was a PostgreSQL index. The database *content* did change
several times (in 3.8.1, 3.8.2, 3.8.3, 3.8.4, 3.8.6, 3.8.8). Note that
if you use the dbconfig-based automatic database configuration, these
changes will be automatically applied on package upgrade.

You're right that (if past experience is anything to go by) the change
from 4.0 to 4.2 is likely to involve more invasive database changes).

At this point I'm inclined to release RT4 packages as
request-tracker4; this at least gives us either option. If anyone
thinks this is a bad idea, now would be the time to speak up.
