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 a LTS version started to be developed too. Therefore, we have now 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. According to this link, the next LTS version is LimeSurvey 3.x.
- 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 2.7x release, LimeSurvey 3 was launched on December 22, 2017.
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, and a template created in 2.73 cannot be used in LimeSurvey 3.
Why did you change the template engines and make them incompatible?
- LimeSurvey 2.50 (now 2.73) introduced responsive default templates, and we had to change the HTML to support this addition.
- LimeSurvey 3 introduced a Twig template system and a template inheritance system which are not compatible with older HTML-based templates.
You can also observe in the screenshots from below the GUI (Graphical User Interface) changes that took place along the time.
