+# Release 3.22.3 (2026-09-02)
+
+* Based on [upstream Nix 2.35.2](../release-notes/rl-2.35.md).
+
+## Parallel evaluation performance improvements
+
+We're continuing to make performance improvements to parallel evaluation, in particular reducing contention on the Boehm-Demers-Weiser garbage collector's global lock by making more use of per-thread freelists and by removing the use of uncollectable allocations in `builtins.fromJSON`.
+
