 ### Added
 
+### Changed
+
+- Payload converters exposed by data converters and workflow/activity accessors
+  retain transfer type conversion, so direct use behaves consistently with SDK
+  serialization.
+
+### Deprecated
+
+### :boom: Breaking Changes
+
+- The OpenAI Agents integration has moved to the independently versioned
+  [`temporalio-openai-agents`](https://pypi.org/project/temporalio-openai-agents/)
+  package. The existing `temporalio[openai-agents]` extra now installs that
+  package, and the old public `temporalio.contrib.openai_agents` imports
+  remain available at runtime and retain their static type information.
+  New code should depend on `temporalio-openai-agents` directly and import
+  `temporalio.openai_agents`.
+- **Experimental**: Nexus Workflow Updates now require `wait_for_stage` to be explicitly set to `ACCEPTED`.
+
+### Fixed
+
+- `contrib.google_adk_agents`: agents with an `output_schema` no longer fail every workflow task
+  when calling the model. The schema type is now sent to the model activity as its JSON schema.
+  Custom Pydantic schema generation is preserved.
+  Integer-valued output enums are normalized to strings to match Google GenAI.
+
+- `temporalio.contrib.strands` activity and MCP tools now give the model the
+  Activity's failure message and expose its exception to after-tool hooks.
+
+- Encoding a datetime search attribute without a timezone now raises
+  `ValueError("Timezone must be present on all search attribute dates")` on
+  the typed path, matching the deprecated untyped encoder, instead of sending
+  a naive ISO string that the server rejects with `BadSearchAttributes`.
+
+- `temporalio.contrib.opentelemetry`: `TracingInterceptor` and `OpenTelemetryInterceptor` no longer
+  log `Failed to detach context` when a context is torn down on a different thread while
+  OpenTelemetry's threading instrumentation (enabled by strands, among others) is active; a
+  context is now detached exactly when its token is still valid in the current
+  `contextvars.Context`, which it stays when a workflow resumes on another pool thread.
