- Native tagging support (and imports UltimateTagWarrior)
- Plugin update notification (time saver!)
- Canonical URLs (SEO’s rejoice)
- Libraries updated: jQuery, TinyMCE, Prototype and script.aculo.us
- New taxonomy system (beware plugin authors)
- Improved Post and Draft Management
- Pending Review (great for multiauthor blogs)
- Unfiltered uploads (smells like security trouble)
Don’t forget to check plugin compatibility, if you’re planning to upgrade.
Looks like i’ll be having a busy weekend.
