Release Notes: A few minor security issues were resolved.
Release Notes: Small security vulnerabilities in the 3.0.7 release have been resolved. It is recommended that you upgrade ASAP.

Release Notes: This is likely to be the last release in the 3.0 branch of Gallery; the next step is 3.1, with many big improvements. This release irons out a few kinks and updates a few last libraries before work stops on the 3.0.x code base. This upgrade should be fast and painless.
Release Notes: This release contains several security fixes as well as a handful of new features. The only major security issue involves someone malicious accessing a copy of Gallery 3 that is not yet installed, so if you already have Gallery 3.0.4 installed and configured, there are no known major issues. However, as always it is strongly recommended that you upgrade to the latest code.
