In preparation of the Drupal 4.6.0 release, development of Drupal core will be frozen on February 1th. During the initial stage of the code freeze, documentation updates, usability improvements and performance improvements will be accepted. New functionality, on the other hand, will not be accepted unless deemed important. Thus, as of February 1th, the focus is to strengthen the code base's performance, usability and stability. As we progress, focus will shift towards stability and near the end of the code freeze, only bug fixes will be allowed, until no release critical bugs are left.
