I upgraded to WordPress 2.5 this afternoon. I used the WordPress Automatic Upgrade plugin (and have used it for the last 4 updates). That went very smoothly.

On accessing the blog, it appears that my host, Dreamhost, has been having a multitude of problem on the particular server cluster upon which I am hosted. At times, over the past two weeks, the blog has been inaccessible. Hopefully they will have everything moved to a new server soon….
