Well, that didn’t take long 
With a few last minute fixes since Release Candidate 2, WordPress 2.7 “Coltrane” is officially released. This is probably one of the most ambitious releases to date, in particular due to the radically redesigned backend interface. [...]
UPDATE 2008-04-16: Well crud. I was just re-reading the WP 2.5 announcement post for something else, and spotted a bit about security updates between 2.3.3 and 2.5. So my previous advice about 2.3.3 being okay was incorrect. This is one of the areas where I disagree with the core developement team — if it was up to me, there would be a 2.3.4 security release for those who have good reasons why they can’t upgrade to 2.5 right now.
Okay, people, if you are running any version of WordPress older than 2.3.3 2.5*, you need to upgrade now. [...]
The first release candidate for WordPress 2.5 was announced last night. The adventurous among you can download it for testing. New features include:
)As a long-time WordPress user and developer, the new design for the back-end admin screens threw me at first. [...]
Okay, I think things are finally (more-or-less) back in shape around here. Sorry about the problems you might encountered here over the past few days. I finally upgraded this site to WordPress 2.1, but I encountered some problems along the way. The problems were really indirectly related to the upgrade, and turned out to be my own dumb fault.
On Friday, I decided to use my lunch hour to perform the upgrade. I backed up my database and my wp-content directory, deleted all the old WP files (I traditionally haven’t bothered with that step, but I knew that several files were renamed/outdated, and I wanted to do some general housecleaning anyhow), installed the new ones, and upgraded the database schema via wp-admin/upgrade.php. [...]
I’ve spent some time converting my Rockem Sockem theme to a Sandbox skin, and getting my Now Playing hack converted into a sidebar widget. I’m more-or-less happy with the results, so I’ll be throwing the switch sometime soon. Be on the lookout for changes around here, and let me know if you spot anything broken.
All WordPress users are encouraged to upgrade to the newest release, WordPress 2.0.4. The new release contains several important security updates, so you are strongly advised to upgrade. In addition to the security enhancements, there are many other small bug fixes, as well.
What are you waiting for? Download WordPress 2.0.4 now!
A couple of buglets snuck by in the WordPress 2.0.3 release. There should be a version 2.0.4 release relatively soon. But in the meantime, check out the WordPress 2.0.3 Tuneup Plugin, by Mark Jaquith. . [...]
The wee hours of the morning saw the release of WordPress 2.0.3. This release fixes a few bugs that have been identified in the past three months, and it also adds some security enhancements.
If you would like a smaller upgrade package, Mark Jaquith has a zip file that contains just the changed files. It’s unofficial, but I’d trust Mark.
Also, if you don’t regularly check your WordPress Dashboard to see when new releases are available, you can also check the project status on Freshmeat.net. [...]
WordPress 2.8.1 Coming Soon
Right on the heels of version 2.8, we will be seeing a WordPress 2.8.1 release soon. There are several minor bugfixes in so far, mostly dealing with tweaks to plugin and menu management. But the big problem driving a quick update is a bug in the core upgrade feature. It seems that in the case where the upgrade can’t be completed for some reason, the upgrade feature was deleting the wrong files when it attempted to clean up. Oops!
On the bright side, when this did happen, it would only delete files that are part of the core package, not any of your plugin or theme files. So the failure could be fixed pretty easily, by just manually re-installing the 2.7.1 or 2.8 files from a zip archive. [...]
