Hello, currently we run the community edition in version 3.15.5 (on our own server).

We have 32 active and running surveys.
Therfore we don't want to enter a risk by updating to 3.24.6 or even to 4.32.6.

Instead we want to install another instance with the newest stable version.
So my question is: What is the newest stable release of the major version 4 ?

Here it says, that 4.32.6 is "unstable": community.limesurvey.org/releases

Where I can get information about the support cycles of lime survey community edition ?

Thanks a lot for this great tool !

Best regards

Currently there is no "latest stable release" of 4.x

The latest stable release of Limesurvey is LS 3.24.6

community.limesurvey.org/downloads/

I think for LS 4.x to be labled stable (again) it will take a couple of weeks/months still. For production purposes I would not use LS 4.x at the moment.

Where I can get information about the support cycles of lime survey community edition?

I don't think that there is a clear startegy of support cycles. Once a new version is out and stable, usually the previous version doesn't receive any new features anymore and is maintaned a couple of months until (official) support is dropped.
