-We released a new set of small patches with [v3.2.1][] (2020-10-02). We're currently working on
-v3.2.2 and v3.3.0.
+Hot on the heels of [v3.2.1][] we've released [v3.2.2][] a mere three weeks later. After this, we're
+going to hunker down for a while, working on our next major release, v4.0.0. We'll be tackling some
+refactorings to simplify the code further, tackle some larger outstanding issues, and focus on more
+development of book 3.
