Can I ask what the tags are for 451 and 452?
DRUPAL-4-5-1 and DRUPAL-4-5-2.
Thanks. Can I just confirm if they are tags or branches ? Do any fixes go into branches for older releases, or is it just a case of updating to the new tag on subsequent releases. (for a production environment, i don't want to risk any problems with following the HEAD)
The DRUPAL-4-5 *branch* is maintained, DRUPAL-4-5-1 and DRUPAL-4-5-2 are *tags* on that branch, and it is possible that there will be a DRUPAL-4-5-3 tag, if enough bug fixes come in. DRUPAL-4-4 is not maintained AFAIK. The HEAD *branch* will be branched into DRUPAL-4-6 later, and obviously is also heavily maintained :) Note that the minor version tags are not used in the contrib CVS module, all modules in the DRUPAL-4-5 branch there are supposed to work with all core code released from the DRUPAL-4-5 core branch, as well as with the latest code in that branch. To put the other way, there are no tags used in the contrib repository, only branches. Goba
