Seems like the 0.9.4 release required a public launch in order to find the last snags. No game, no pain, or something. The changes are:

Action Mailer

• Fixed sending of emails to use Tmail#from not the deprecated Tmail#from_address

Action Pack

• Fixed bug in page caching that prevented it from working at all

• Fixed a bug where cookies wouldn’t be set if a symbol was used instead of a string as the key

• Added assert_cookie_equal to assert the contents of a named cookie

Active Record

• Fixed that the belongs_to and has_one proxy would fail a test like ‘if project.manager’ — this unfortunately also means that you can’t call methods like project.manager.build unless there already is a manager on the project #492 [Tim Bates]

• Fixed that the Ruby/MySQL adapter wouldn’t connect if the password was empty #503 [Pelle]

Rails

• Added 5-second timeout to WordNet alternatives on creating reserved-word models #501 [Marcel Molina]

• Fixed binding of caller #496 [Alexey]

…you may need to use “gem install rails”, and not just “gem update”, to install the latest version.
