Besides all the API and structure changes, the code has been rewritten to use D7's new Database API. Most notably, the . (dot operator) concatenation of the database name and table prefix has been removed in favor of switching databases Database::addConnectionInfo and db_set_active().
The 7.x branch has been opened! This will first off be simly going through the Coder module's messages, and updating function calls. DB changes will be the hardest. Hopefully I can get this branch stable and functioning!
