Mozilla 1.3 is out. The most compelling new feature for me is Midas, rich text editing controls for the browser. Here's a demo (works in Moz 1.3 only, of course). I hope web-based content management systems pick up support for this toot sweet when they detect a Moz 1.3 browser. I'll probably add it to my blog editing interface as soon as I can figure out how it works.

Moz's new junk mail filtering capabilities seem to be a big deal (they're Bayesian!), but I'm having 100% success with my server-side filters, so I won't touch it until I need it.
