I remember when I first trial tested Open Source Content Management Systems to build a personal website, it was right on the cusp of Drupal 5 in January 2007. I installed Drupal 4.7 since that was the stable release at the time, and then was bombarded by bugs. Lots of bugs. At the same time, there was the beginnings of a really sweet system that would allow me to manage user accounts, access levels and even support the customization of content types. The next week, Drupal 5 hit the streets and I remember crossing my fingers during installation, having it all go smoothly.
