WordPress 2.6.5 has been released which is probably the last release in that branch till 2.7 goes official. It represents a pretty important release because there’s a security hole that has been blocked, together with a couple of minor fixes.

The WordPress team recommend that you upgrade to this latest version, but in my case I don’t think that the security hole actually applied to my sites as it’s pretty specific (it only affects IP-based virtual servers running on Apache 2.x). I may push my sites to the 2.7 beta instead which is working remarkably well on this site.

It’s really up to you and it doesn’t matter whether you’re running a website talking about the best memory upgrade or selling teryx accessories, it’s always good to know what releases are available and if you need to apply them or not.
