After almost two months since RC2 release the next (and hopefully last) release candidate is now available! Among dozen of bugfixes there have been two areas worked on intensely: The Central Participants database (many issues were fixed here and new features added) and the new RemoteControl2 API (based on JSON-RPC/XML-RPC). Please note that the coding of the RemoteControl API was exclusively sponsored by your donation money! Let us know if you think something is missing. We invite everyone to have a look at LimeSurvey 2.0 and ask you to report any issues back to us as soon as possible. Only that way it can quickly become stable for a full release.
Update: We are at RC7 now because we have been reported two show-stopper bugs. Thank you for the feedback!
