+## 0.9.0.7 (2019-01-04)
 
 Note that this will be the last release in the `0.9` series, excepting
 critical bug fixes or security issues. The next release is expected to
 (slightly) break module export compatibility, but in a way that should
 not affect too many users.
+
+Changes:
+
+  - Support for Stackage LTS 12, LTS 13.
+  - Support for GHC 8.4.4, 8.6.3.
+  - Copyright for the project has been re-assigned to Drew Hess, its
+    original author.
+  - Drop support for nixpkgs-stackage overlays, no longer maintained
+    upstream.
