I spent yesterday and today upgrading my Colombia site to Drupal 4.5.0, after my host had moved my site to a new server. Drupal wasn’t hard to upgrade, it has a pretty decent upgrade script, even though I had to move first to 4.4.0 and then to 4.5.0. I ran into an error in 4.4.0, but after upgrading to 4.5.0 it dissapeared :)
Meanwhile, I am also setting up as an independent information architecture consultant. Tips on consulting books and accounting software are very welcome!
