1.3.2 fixes since 1.3.1:
* Fix namespaced page creation links when no go match
* When cookies are disabled, don't show login screen twice
* Install should no longer die when PHP is pre-configured to
compress output
* Fixed bug that caused long Japanese pages to time out with Tidy
active
* When session.handler is set incorrectly, try automatic
override to 'files'
* Watch/Unwatch links back to the affected page instead of Main Page
* Upload link no longer displayed on Monobook if uploading is
disabled
* Special:Allmessages faster, shows correct original text, works
in safe mode

Anyone still running the 1.3 beta releases is _strongly_ recommended to
upgrade to the current code due to numerous fixed bugs and a security
vulnerability in the betas with some PHP configurations
