there is a teaser page on all the features of wordpress 2.5 today on the wordpress blog. I suspect 2.5 will be released tomorrow or on the 30 or 31st of this month.
I have been holding off on doing some big changes to this blog until after 2.5 was released. I am going to goto registered only comments at some time in the next month or so which probably sounds like a hassle but be assured there are major benefits coming with this too.
You should really read that blog post to see all the changes. 2.5 is a major milestone and there are a TON of new and improved things. Looking good.
