You can see a sneak peek video here, featuring the new features in wordpress 2.5 blogging software. If you haven’t got wordpress for your blog, I highly recommend it. I love the software so much I actually use it for non-blog sites too(and modify it to make it not look so much like a blog).

With that said though, 2.3.3 has a couple major exploits people are reporting allowing hackers to insert hidden spam(one on stanford university, the other on shoemoney blog). I know I was a victim of a exploit in 2.3.2, but that was fixed in 2.3.3. 2.5 release candidates I don’t think would solve it because they are just adding new features. I hope they fix these new exploits soon in a future 2.3.4 patch release.
