+## [v1.3.1] - 2026-04-20
+
+### Changed
+- Fixed an incorrect assumption in `start_worker` that the loopback `bind_addr`
+  would be IPv4, which is untrue on macOS. This fixes silent hangs during
+  precompile on macOS, and also ensures `start_worker` errors are properly
+  reported ([#68]).

 ## [v1.3.0] - 2026-04-06
