If you're not tired of reviewing release notes (I'm sure getting a bit
tired of writing them), see
http://git.postgresql.org/gitweb/?p=postgresql.git;a=commitdiff;h=eb7de00ac2d282263541ece849ec71e2809e9467
guaibasaurus should have 'em up on the web in an hour or so, too, at
http://www.postgresql.org/docs/devel/static/release-9-5-3.html
