What were the reasons for the relaunch?
It became increasingly difficult and time-consuming to manually edit HTML files, esp. when you have to update links back and forth between pages everytime you add or remove a page. Doing this automatically is a huge time-saver and it prevents broken links and similar mistakes. We also wanted to upgrade from “HTML 4.01 Transitional” to “XHTML 1.0 Strict” so we had to overhaul all HTML files anyway. Now that most but the weirdest browers’ Cascading Style Sheets’ support has become ubiquitous, we’ve finally been able to get rid of the old tables-based layout (hack), replacing it with a more flexible CSS-based layout.
