If you run a self hosted (wordpress.org) site, this morning you will be able to upgrade to the latest version 3.3.
Some of the new features are:
Better dashboard menus, these just fly in and fly out on mouse over now, rather than having to click on each heading to see the sub menu.
Smarter Admin bar, more in keeping with the new look wordpress.com version
Drag & Drop File Upload, no browsing for files any more, no just drag them and drop them in to the upload area and off they go. File type detection is also built in.
Widgets no longer go AWOL when you swap themes
Tumblr has been added to the import list
Co-editing posts, the post now unlocks as soon as it has been saved. If you have a number of contributors on your site, how many times have you spotted a typo on a new post but not been able to edit it because it is locked? Well now as soon as a user comes out of a post it will be unlocked so you can edit it, instead of waiting for wordpress to remember to unlock it.
I have upgraded a couple of blogs this morning and all seems well and I’ve not come across a plugin that has failed after this upgrade (yet!)
