We have just finished the migration of the K2 code repository from Google Code to Github.
The new code repo is now located at: https://github.com/joomlaworks/k2
So why this move to Github you ask? Well, Github will now make it a lot easier for casual developers (and experts of course) to submit code to the K2 code base. Previously this was a very tedious process with Google Code, such that most third-party additions or improvements were essentially completed manually via the bug tracker.
This also means that bug solving will now be a lot faster and more transparent.
Finally, since we're moving to a new code repo, you'll notice that http://getk2.org/bugtracker
now properly redirects over to the Github "issues" section of the K2 project.
We also plan to utilize Github's "wiki" features to gradually have a proper and up-to-date documentation on the latest K2 code base.
Happy coding! More...
