What does <project version="4"> refer to in XML files under /.idea?
It appears that every XML file under /.idea in a PhpStorm project contains <project version="4">. What does this refer to?
It doesn't seem to be the version of PhpStorm that I'm running, since that's actually 2017.2.4. It doesn't appear to be anything specific to my project, as this value is the same in a bunch of unrelated projects.

Hi there,
It's just a version of the schema used by project config files (as in "protocol/format version"). It's purely internal thing and has no relation to user end.
Thanks! I was considering committing configuration files in a repository that would be used by other people, and I wasn't sure if <project version="4"> was something that I should expect to change in the future and need updating, or something that I could safely ignore.
