Is there any estimated release plans (release date) with PHP 8.0 support?
I'm planning to renew the support subscription but only after the release is on

Thanks for question.
Major releases of PHP are always bringing a lot of changes in the IDE. We have to develop new internal parser for this version that will support all php features 1:1, we have to update CodeInsight, docs, php standard definitions, debugger, refresh all the libraries that we depend on, Can't say for sure when we'll finish this all. Originally planned for Feb, but it's obvious we're slipping.

Thanks for hinting!
