 - Revamped JS execution model to be out-of-thread. Python/C++ interaction now happens
     via callbacks. 
 
 - Consequently, Control+C (`KeyboardInterrupt`) now interrupts JS execution.
 
+- Hardened C++-side thread safety model, resolving potential race conditions introduced
+    in v0.8.1 (but not actually reported as happening anywhere).
+
+- Further improved JS exception reporting; exception reports now show the offending code
+    where possible.
+
 - Introduced `timeout_sec` parameter to `eval`, `call`, and `execute` to replace the
     `timeout`, which unfortunately uses milliseconds (unlike the Python standard
     library). In the future we may emit deprecation warnings for use of `timeout`.
