# Upgrade notes for FriendsOfBehat/MinkExtension This document summarizes the changes relevant for users when upgrading to new versions. # Upgrade to 2.8 ## Soft `@final` and `@internal` declarations added The classes `FailureShowListener`, `SessionsListener` and `MinkExtension` have been marked as `@final`. They will become `final` classes in the next major release and you will no longer be able to use them by inheritance (https://github.com/FriendsOfBehat/MinkExtension/pull/41). Additionally, the two listener classes have been marked as `@internal`. Starting with the next major version, their API may change at any time without further notice.
