Gallery 3.0.8 is now available! We're hard at work on 3.1, but in the meantime two security researchers identified small security vulnerabilities in the 3.0.7 release. We've patched them and recommend that you upgrade to 3.0.8 ASAP. Thanks to Mala and Dhaval Chauhan for their responsible disclosure. We'll be rewarding them cash bounties as part of our Security Bounty Program.
