This release fixes SA-CONTRIB-2012-103 - Global Redirect - Open Redirect.
This is the first tagged release in a LONG time. Many bug fixes since 1.2. There was a 1.3-alpha (and no official 1.3). I have intentionally skipped 1.3 to bring it into line with the D7 branch which is also now on a 1.4 tagged release. Hopefully we can keep both branches in version-sync.
This release fixes a security vulnerability, all users of Meta tags quick 7.x-2.2 and lower, or any 7.x-2.x-dev snapshot from before 2011-12-14 are urged to upgrade. For more details, see SA-CONTRIB-2011-059.
