This post was made on a local copy of the Hoeben.net website. I am trying to upgrade Drupal to version 4.6 (up from version 4.4.3)
So far, things are going ok-ish. What kept me back before was that I did some customisation to the menu module that isn't even available for Drupal 4.5 and up because parts of its functionality are now in a core Drupal module. As a result, the menu system will need some work to get it back to where it was.
One of the neater modules available in Drupal 4.6 is the tinyMCE WYSIWYG module. It's a pretty dramatic improvement over typing HTML code into a standard text area. Unfortunately it conflicts with the linewrap filter in Drupal, so I am turning that off for new content. But then again, posts made through other interfaces such as XMLRPC should ideally still use this filter so users don't have to add <p> tags manually...
Come to think of it, it would be a good idea to have the input format configurable for the blogapi module.
*UPDATE* fixed the blogapi module so you can select an input format.
