The CVS repository used to be very forgiving in what it considered a valid release tag, especially in the 'extra' portion of the tag name. This lead to all sorts of wonky tags that creative developers came up with. My least favorite are the official release tags that end in "-dev", utterly blurring the distinction between official releases and development snapshots. Now, your official release tags must match the format documented here: http://drupal.org/node/93999 For the regexp-enabled, your tag must match this: @^DRUPAL-[567]--(\d+)-(\d+)(-(ALPHA|BETA|RC)[0-9]+)?$@ For the non-regexp-enabled, that basically means that the optional part after the drupal core branch name (e.g. "DRUPAL-6") and the required two digits for your version string (e.g. "--1-0") must be either "ALPHA", "BETA" or "RC" followed by 1 or more numbers. This will also prevent people from abusing the "extra" portion of the tag name as if it was another digit in the version string. 5.x-1.2-1 or 5.x-1.2.1 is no longer allowed. This was never supported, never intended, never documented, and update_status doesn't know what to do with it. Now, you can no longer create tags like this. The next release after 5.x-1.2 should be 5.x-1.3... For history and discussion of this change, see this issue: http://drupal.org/node/252473 Apologies I never locked down this regexp earlier. ;) Cheers, -Derek (dww) p.s. Please don't reply here. If you'd like to discuss this change, reply to issue #252473. Thanks. p.p.s. Nothing changed about the format of valid branch names. Those never had much flexibility in the first place, so there's no problem there. p.p.p.s. Before you write a nastygram about what a tyrant I am, please be aware that webchick, killes, merlinofchaos and pwolanin (among others) all support this change. ;)
