MarsEdit is a great piece of desktop blogging software for Mac users, my personal favorite by the way. As with most desktop blogging software, it can be a bit troublesome when the actual blog platforms, such as WordPress or Movable Type, updates to a newer version. Well, WordPress 2.5 apparently gave MarsEdit a few issues with drafts, so the 2.1.3 release fixes that, and does the same for Blogger as well.
