Version guide

Version Numbering

To understand the version numbering, remember that version 2.06 was preceded by 1.92, 2.00, and 2.05. LimeSurvey 2.06 is our "starting point" as it is the moment in which two versions have started to be developed. Therefore, there is a(n):

• LTS version: 2.06LTS. It was later renamed to 2.6.x on October 24, 2016. This version will be supported until the launch of the next LTS version.
• up-to-date version. The first up-to-date version after 2.06 was 2.50, which was released on February 2, 2016. Since then, new features have been added with the releases of LimeSUrvey 2.6x.x and 2.7x.x. After the last release of 2.7x, LimeSurvey 3 was launched on December 22, 2017.

Differences

All three major LimeSurvey versions described below use different template engines. This means that a template created for LimeSurvey 2.06, cannot be used in LimeSurvey 2.73 or LimeSurvey 3.

Please note that the Template editor was renamed in LimeSurvey 3, being called now Themes.

You can also observe in the screenshots from below the GUI (Graphical User Interface) changes that took place along the time.
