My web server is somewhat older and does not support PHP8, just wondering how long I would be able to get away with it running 1.15.x for?
Kepnate Typically, until 1.17 comes out. Generally the two most recent versions are supported, which is why 1.14 dropped off the list when 1.16 was released. Of course, if version 2 comes out before a 1.17, then this will change!
