The LimeSurvey team is proud to release the first alpha Version of LimeSurvey 2.0. This new version has come a long way and basically is a port of LimeSurvey 1 to a complete new codebase. It is NOT a complete rewrite which we intended to do a couple years ago - unfortunately we lacked resources to ever complete that one so we decided to go this much more transitioning way. However LimeSurvey 2.0 does not lack new features.
Beside the port to a PHP framework the new version most notably sports a new condition engine which we call Expression Manager (EM). Currently it runs in parallel to the old condition engine and will on a short term replace it completely. EM makes it possible to use advanced piping, micro-tailoring and complex equations to decide if a question is visible/relevant or not. Also LimeSurvey offers now an archive format which makes it possible to archive & download a complete survey in its current state (including responses/timings/tokens). You can restore it later again at any LimeSurvey installation. There are many more new features - click 'Read more' below to learn about it.
