William FHandGitHub acae5e23b0 chore(sdk-py): cron tz support (#7108) 2026-03-10 17:38:02 -07:00
Sydney RunkleandGitHub 46fed9d161 feat: type safe stream/invoke w/ proper output type coercion (#6961) 
Adding type safe streaming + more robust pydantic + dataclass support on
graph outputs

* type safe streaming via #6931 
* type safe invoke via
https://github.com/langchain-ai/langgraph/pull/6963
* actually thread through types via parametrization in
https://github.com/langchain-ai/langgraph/pull/7009
* deprecation of backwards compatible accessor via
https://github.com/langchain-ai/langgraph/pull/7011

full spec of changes:
https://github.com/langchain-ai/langgraph/issues/7008
proving out that required changes are minimal even when we update the
default to v2: https://github.com/langchain-ai/langchain/pull/35541

 		b89ef60b91 feat(sdk-py): add extract parameter to threads.search() (#6880) 
## Summary
- Adds `extract` parameter to `threads.search()` in both async and sync
clients
- Adds `extracted` field to the `Thread` TypedDict response type
- The `extract` parameter accepts a `dict[str, str]` mapping aliases to
JSONB paths (e.g., `{"last_msg": "values.messages[-1]"}`)
- Depends on server-side support in
https://github.com/langchain-ai/langgraph-api/pull/2609

## Test plan
- [ ] Verify types are correct via lint/format (already passing)
- [ ] Integration test against server with extract feature enabled

Release Notes: Add `extract` parameter to `threads.search()` for
extracting nested values from thread data during search.

 		9babffa054 feat(sdk-py): add stream_mode, stream_subgraphs, stream_resumable, durability to crons (#6876) 
## Summary
- Adds `stream_mode`, `stream_subgraphs`, `stream_resumable`, and
`durability` parameters to cron `create`, `create_for_thread`, and
`update` methods in both async and sync clients
- Adds corresponding fields to the `CronUpdate` TypedDict in `schema.py`
- Adds `checkpoint_during` deprecation warnings to cron create methods
(consistent with the runs client pattern)

These fields were added to the OpenAPI spec in langgraph-api but were
not yet reflected in the Python SDK.

## Test plan
- [x] `make format` passes
- [x] `make lint` passes
- [x] `make test` passes (69/69, including sync/async API parity test)

Adding support for the `context` arg to `invoke/stream` to the sdk. This
is paired with an update to the API as well that adds `context` support
to the `assistants` and `runs` endpoints.

Bumping version to v0.2.0 on the `v1` branch given this and the
interrupt schema changes.

* Use dynamic versioning
* Bump `pydantic` to v2.11.4 in the lockfile, we have some tests failing
