The Drupal developers have been little busy bees ever since the new development branch has been created about 1.5 months ago. Those that do not track the CVS commit messages or read the mailing lists might wonder what we have been up to, so let me provide you with a quick run-down of the progress we have made.
Early on, just before the CVS tree was opened up for development, the developers were asked to identify the "smellier parts" of Drupal. As soon these areas were identified, we immediately began to tackle them. As such, the past 1.5 months, the majority of our time was spent improving Drupal's innards.
