+- Improved orchestration and entity execution performance by reducing replay
+allocations, caching handler and entity-method signature metadata, and
+serializing history-export events in a single pass. These changes reduce CPU
+and memory overhead for long histories and high-frequency handlers without
+changing serialized output or handler behavior.
 - Importing `durabletask` no longer eagerly imports the worker implementation and its
 dependencies (gRPC, protobuf, entities, serialization, OpenTelemetry). The public names
 re-exported from the package — `ActivityWorkItemFilter`, `ConcurrencyOptions`,

 CHANGED
 
+- Updated the minimum `durabletask` dependency to v1.9.0. Its reduced replay
+allocations, cached handler metadata, one-pass history serialization, and
+bounded async work-item task creation improve orchestration and entity
+throughput and memory efficiency for Durable Functions applications.
+- `FailureDetails.error_type` now uses fully-qualified type names, and
+`FailureDetails.is_caused_by()` provides base-type-aware matching. See the core
+`durabletask` changelog for compatibility details.
 - Reused host-driven orchestration and entity workers across invocations,
 avoiding repeated allocation of unused worker resources.
