I upgraded my WordPress to 2.3.1 today. I followed the instructions on this page and everything went smoothly. No problems whatsoever.I also started using MarsEdit 2.0.3 to write my blog posts. This is the first one I’m writing using MarsEdit. It seems like a nice Cocoa application, though I’m not sure what its benefits are compared to WordPress’s own browser-based writing tool. I guess I’ll have to continue using both to figure that out. (I just noticed that MarsEdit has a find-as-you-type spell checker. Nice.)
