Ah, oops. I figured I wasn't going to bother with any upgrades until the
bug was fixed, and forgot you might only mention the bug fix in the
release notes. Sorry!

I've now built the new version, and will try deploying this evening.


Incidentally, building a new version of dovecot has reminded me of a
problem I encountered building under OpenBSD (version 3.2). When
using dlsym() to find C symbols in shared objects, the symbol name
must be prefixed with an underscore. For the time being, I've fixed
the issue with the following shim in src/auth/auth-module.c :
  97a98
  >       char buf[64];
  101c102,106
  <       ret = dlsym(module->handle, name);

Without that fix, using modules for auth_userdb or auth_passdb won't
work.

I'm sure there must be some elegant way to deal with this portability
issue, but for the moment it eludes me. (-8
