+# Highlights
+
+## Bugfixes
+
+- Fixes an issue with versioning in signal handlers leading to non determinism.
+- Fixes an issue with ScheduleClient not throwing an exception on a failed create
+
+## Readonly Protection
+
+Added protection in the SDK against running mutating workflow functions in a read only context.
+A read only context is a query handler, update validator, side effect, or mutable side effect.
+Previously, in some cases, the SDK would seem to allow it but silently generate an invalid workflow history.
+This change allows developers to quickly catch their mistake and prevents generating invalid workflow histories
