+## 1.10.1
+
+**Release date:** 2026-10-26
+
+This patch release hardens the controller's artifact server by setting a read
+header timeout, which also bounds the TLS handshake, and an idle timeout. As a
+result, connections that never send a request, or keep-alive connections from
+clients without an idle timeout, no longer stay open until the server shuts
+down. No timeout is set for reading or writing the whole request, so large
+artifacts can still be downloaded by slow clients.
