Version 0.2 of the Bugzilla REST API has been released. New in this version:
- Read/write support for flags, groups, custom fields and comment privacy
- Access to all aspects of Bugzilla’s configuration with a new /configuration call
- Even more high-quality and comprehensive documentation
- Better logging so I can debug problems
Note that these new capabilities will not be available on the copy of the API pointed at bugzilla.mozilla.org until the upgrade :-( But in the mean time, you can test them on the staging server. Although that seems very slow at the moment.
I consider this the first version of the API with which you should be able to write a capable Bugzilla client of some sort. Let me know if you find stuff missing which would be required for this usage.
Lastly, there is now a Bugzilla component for you to file bugs in :-)
