Huh, my browser history says I downloaded the source, yet it was nowhere to be found. Sorry for the delay. (Note: 8.3.2 source was never released)
One big change, and warning for old versions – I removed Bonjour support. For some reason that I’m looking into, a Bonjour connection is always trusted, regardless of how role permissions are defined in pg_hba.conf. And since I could find no way to turn Postgres Bonjour off, I had to remove it completely from the binary.
If you don’t completely trust users on your local network (and need to allow local network access), you should upgrade. If you only access Postgres from the same Mac (external access thru phppgadmin is technically local access) you’re OK. Hopefully it’s just some hba configuration I’m missing.
