WordPress has released an update to address close to thirty maintenance and security issues found in release 3.1.
Some of the notables:
- Some security hardening to media uploads
- Performance improvements
- Fixes for IIS6 support
- Fixes for taxonomy and PATHINFO (/index.php/) permalinks
- Fixes for various query and taxonomy edge cases that caused some plugin compatibility issues
I just finished an auto-upgrade and suggest you either Download WordPress 3.1.1 or do an auto-update from the Dashboard of your WordPress installation.
Only the geeks know
What half this stuff even means
Don’t worry — update
