   Trying out Nix on your aarch64 or i686 Android device is now easier than ever.
 
+- Two big stdenv cleanups [Enable `__structuredAttrs`](https://github.com/NixOS/nixpkgs/pull/72074) and [treewide: `set -u` everywhere](https://github.com/NixOS/nixpkgs/pull/72347)
+
+  It's time to clean up stdenv!
+  By making our code less fragile, we increase the budget for interesting features. 
+  There should be plenty of failures, but many of them independent so we can easily parallelize the work to fix.
+  Please come pitch in!
