Wikitravel:11 April 2006
The software upgrade was a mitigated success. I had to take an extra hour tracking down a problem with interwiki links (our WikiPedia and Dmoz links weren't working). Once that was done, the rest has been mostly reasonable, although the performance on the site is poor since I had to clear all the caches.
The main visible changes from this upgrade are 1) default template parameter values and 2) a split between the login and register pages. There are a lot of little interface changes around the software, too.
Admins on non-English versions should watch out for "creeping English" for new features, etc. Also, as I was hand-merging Wikitravel's LanguageXX.php files with the upstream versions (note: probably erroneous), I noted a number of places that previous prompts had changed, so watch for that. It'd be great if admins on non-English versions could take care of these problems using the database messages.
