Upgrade to Wordpress 2.5

Finally, after almost 3 years running the same version of Wordpress for this weblog, I finally upgraded to Wordpress 2.5. The upgrade went smoothly except for a permission problem at the end which is documented in Wordpress forum.

Kudos to Wordpress team for releasing a web application which can upgrade a 3-year old version without any user intervention (almost...) while preserving all my content.
