+Highlights:
+
+This release is focused on providing new Search Attributes functionality:
+  - New `Workflow.getSearchAttribute(String)`, `Workflow.getSearchAttributeValues(String)`,
+    `Workflow.getSearchAttributes()` methods to get deserialized search attributes
+  - unit tests can register new search attributes on both Test Server and dockerized Temporal Server
+  - unit tests can use Test Server to verify search attributes behavior and implementation.
+
+Test server exposes new gRPC TestService providing time skipping API to be used in other SDKs.
+
+An upgrade of Temporal Server and Temporal docker-compose to 1.16 is highly recommended to use the new Search Attribute APIs.
+
+Fixes:
+
+- Edge case of "unexpected event WORKFLOW_TASK_COMPLETED" when querying a non-completed workflow evicted from sticky cache #1134
+- Deadlock Detection may cause "Operation allowed only while eventLoop is running" in the workflow code #1127
+- Protobuf version range that was making 1.8.x release hard to use with Maven
