As announced here, the final version of WordPress 1.5 has been released.
This site has been operating with the beta versions of 1.5 for some time – even when it was still 1.3 – and I can fully recommend it, especially over and above 1.2; it’s a pretty big step up in terms of functionality and coolness factor.
If you are using WordPress 1.2, I would suggest you go ahead and move to 1.5 as soon as possible. Be aware that the default site template has been changed, but the updater should move your old template into a new directory and transition you into the new system with ease. There’s a lot of neat things that work differently in 1.5, and a lot of new features that are really useful – many of them are detailed on the linked post.
If you are at all interested in blogging, and use a different system, I would encourage you to move to WordPress and use it as your primary system. I have been operating with it for quite some time now; probably about a year; I used Movable Type before that, but Six Apart sold out, so I decided to move elsewhere. If you need assistance with setting up a WordPress installation, or even are a friend of mine and need a place to host it, I would be more than willing to help you out with that.
Now if you’ll excuse me, I have to go and install 1.5 final myself over the nightly build I’m using now.
