Drupal CVS branches and tags

To manage the different Drupal versions, we use tags and branches.

A branch specifies a major Drupal version. For example, all 4.7.x versions of Drupal core belong in the DRUPAL-4-7 branch. The HEAD branch is special and is used to refer to the latest development version. For more detailed explanation of the HEAD branch, click here.

Whenever we release a specific version, we create a tag. A tag is a marker which defines a snapshot of all the files in the CVS at a certain moment. For example, the tag DRUPAL-4-7-4 specifies all files at the time of the Drupal core 4.7.4 release.
