WordPress 2.7 has been out since 11 December, I sadly current get to a computer to write a post until now but here it is.
There’s been some Major changes to the back-end admin page design and some new keyboard shortcuts.
Plus 2.7 also allows comments to be split into pages and threaded.
WordPress 2.7 makes it even easier to upgrade with built in core updates similar to the plugin updater in 2.6.
The guys at automattic put a video together showing some of the changes.
