Hi, We are planning on installing 4.x into a prod environment. From what I read it still seems to be not recommended.
Should we stick with installing 3 LTS .

One of the requirements of 4 is PHP 7, however in git it still mentions 5.5 is required.. could this be clarified?

For production I still wouldn't go with LS 4.x. There are just too many open bugs that I might consider too problematic for production.

At the current status, I would definitely go with the latest version oLS 3.x LTS.

Well, since PHP 5 is EOL and no longer supported, you will go with PHP 7.2 or PHP 7.3. PHP 7.4 had some issues with LimeSurvey.

so 3.x LTS with PHP 7.3?

Yes, PHP 7.2 or PHP 7.3 will work fine.

And if there are issue with PHP7.4 : open a bug report : it must be fixed (i think it was already)
