Yes, it’s only ten days since I mentioned that WordPress 2.0.6 was available, but a combination of the FeedBurner issue and a nasty security problem that could be a major problem for WordPress installations on some servers has led to the rather rapid release of WordPress 2.0.7.
This is a security update, and all WordPress users are advised to upgrade. If you’re already on 2.0.6, you just need to replace six files, which are listed on the Development Blog. If you’re on an earlier version, you might want to look at Bryan Layman’s nifty upgrade script. I used a slightly earlier version to get to 2.0.6, and a much earlier version for 2.0.5, and it worked nicely for me.
However you upgrade, make sure you do.
Version 2.1 is scheduled for release this time next week. But if you’re not ready for the major changes that will bring, don’t worry – the developers will continue to maintain 2.0.x for a long time to come.
 And if not, you should be!
