No documentation about minimum requirements
I found nowhere any information about the minimum requirements and supported versions. E.g if I want to commit a bug fix for something apache related, do I have to care about version 2.2 or only about 2.4. From when on will ISPconfig get rid of older versions? Are there clear rules that e.g the last two main versions of each software is supported?
It would be great if here in gitlab in the wiki would be one detailed page of what is supported and what not. So that new developers have a guideline what they can commit and what not.
