While I was asleep, another WordPress update escaped. For those not playing with the 3.1 development, WordPress 3.0.5 has some security patches that are mostly of use to sites with multiple users, but there are some other bits in there you’ll want.
For 3.1 users, RC4 includes the security patches mentioned above and fixes some of the remaining bugs.
The final release can’t be far away now:
After nearly five months of development and testing, we think we’re very close to a final release. Users and developers, please test your themes and plugins.
Full details and download links are on the WordPress development blog:
 Maybe I should set up an alarm
 Not that there’s anything wrong with staying with the main releases
