|
| |
|
| Understading the semantic versioning of LimeSurvey might be a little bit tricky. First, to check all the past LimeSurvey versions, you may access the following [https://github.com/LimeSurvey/LimeSurvey/blob/master/docs/release_notes.txt] link.

|
| |
|
| The most important updates are described below:
| | To understand the version numbering, remember that version 2.06 was preceded by 1.92, 2.00, and 2.05. LimeSurvey 2.06 is important because this was the moment in which LimeSurvey started to provide: |
| | | *a 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. |
| {| class="wikitable" style="text-align: center"
| | *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. |
