You may have noticed from either the "Integration Updates" table above, or my signature image:

that the development of integrations has slowed somewhat. While the release of new updates has slowed, behind the scenes development has not.
The next version of Gallery, Gallery 2.3, will have some great new features available to integration developers. These features will allow integrations to:
- Render any G2 module block in the integration
- Over-ride G2 themes
- and more, to be outlined later
Additionally, the phpBB3 integration has been kickstarted again. Look for an official release announcement here soon. The phpNuke release will be updated to take advantage of the new functionality in 2.3, and will be much more robust. Also, a complete rewrite of some sections of the integration will take place to resolve most of the user errors, and add new functionality (most ported from the phpBB2 integration). Stay tuned, lots of great things are on the way :)
