 ## v4.x
-In December 2020, we released v4.0 stable after a long time. From now on, we'd like to release new features and bugfixes often.
-In subsequent v4.x releases, we intend to implement the next features in non-breaking ways.

+We've completed active development on v4.x, but we'll still fix important bugs or add small enhancements on request that don't require breaking changes nor lots of testing.
 
-## vNext
-We have interest in the following topics for future versions.
-Some cannot be done in v4.x the way we'd like without introducing breaking changes.
-Others require more exploration first, or depend on other features.
