Your understanding of how perpetual licenses with upgrade subscriptions work is correct.<p>Also, you can still be pretty confident that as a language support by an IDE (PhpStorm in your case) evolves, new versions will be supported by this very IDE, and we don&#x27;t have any plans to release a separate Php7Storm :)<p>I was referring to a different kind of change where you might switch from PHP to Ruby, from C# to Java. C# and PHP are naturally not the best combination to support in the same IDE, meaning you might switch your tools as you go from language to language.
