Mere days after upgrading to WordPress 2.3.3, I’ve now upgraded to WordPress 2.5. Sean brought out that due to a security vulnerability, Technorati stopped indexing compromised blogs and strongly encouraged all 2.3.3 users to upgrade to 2.5. Say what!
The new 2.5 Dashboard is a lot slicker and web 2.0ish. Lots of Ajax and/or Javascript integration, which is nice. Things are moved around a bit which will get a bit of getting used to.
I’m totally psyched about the improvements to the editor area. I hated how it would mess with HTML code. I will hastily update the food blog, as this was one major reason why I never posted there; every post was a headache to format properly.
Maintenance Mode plug in broke on the update for me - I was logged in yet I kept getting the maintenance mode screen (which ought only to appear when not logged in). I had to delete the poor pansy. Perhaps a new rev is in store.

Ugh, yeah I experienced the same thing. It’s irritating because they recommend installing the plugin on the upgrade instructions page and then it breaks.

Yes, I am extremely surprised that WordPress does not update the copy on the upgrade instructions page to remove that, or to at least make a note of the incompatibility.

Nice work, now just install Fluency and your WP2.5 experience will be complete.
