There is a new release of WordPress, 3.0.2. Should you upgrade to it? YES! Here is what WordPress says about it –
This maintenance release fixes a moderate security issue that could allow a malicious Author-level user to gain further access to the site, addresses a handful of bugs, and provides some additional security enhancements.
If you have followed me for awhile you know that I do not recommend letting people register for your blog. This release seems to be geared to those of you who DO allow people to register. However, even it you don't let people register, it does provide some 'additional security enhancements'.
I always recommend doing these security upgrades. There is nothing new in them so they are relatively harmless to install but provide great benefits to you.
