github-actions[bot] d2ca90f8e2 chore: version packages (#2453 )

This PR was opened by the [Changesets
release](https://github.com/changesets/action) GitHub action. When
you're ready to do a release, you can merge this and the packages will
be published to npm automatically. If you're not ready to do a release
yet, that's fine, whenever you add more changesets to main, this PR will
be updated.


# Releases
## @langchain/langgraph-checkpoint@1.0.4

### Patch Changes

- [#2344](https://github.com/langchain-ai/langgraphjs/pull/2344)
[`0125920`](https://github.com/langchain-ai/langgraphjs/commit/0125920a2c4a87dc1d66aaf541ea16146f8cf842)
Thanks [@dependabot](https://github.com/apps/dependabot)! - chore(deps):
bump uuid to 14.0.0 and keep checkpoint ID ordering stable

Bump `uuid` from 10.x/13.x to 14.0.0 across packages. Starting with uuid
11, `v6({ clockseq })` no longer advances the sub-millisecond time
counter when an explicit `clockseq` is passed, so checkpoint IDs created
within the same millisecond were ordered only by `clockseq`. Since
checkpoint IDs are sorted lexicographically, this broke ordering — most
visibly for the negative `clockseq` used by the first ("input")
checkpoint, which sorted as the newest.

`uuid6()` now maintains its own monotonic `(msecs, nsecs)` clock
(mirroring uuid 10's internal v1 behavior) so the time component is
always strictly increasing and checkpoint ordering no longer depends on
the `clockseq` value. `emptyCheckpoint()` also uses a non-negative
`clockseq`.

Assistant-UI Claude Example

This example combines:

@assistant-ui/react for the Claude-style chat surface
@langchain/react for streaming LangGraph state on the frontend
a basic langchain agent on the backend

What it shows

A Claude-inspired assistant-ui thread and composer
A local single-agent graph powered by langchain
How to bridge @langchain/react state into assistant-ui with useExternalStoreRuntime

Setup

Create a local .env file in this folder with:

OPENAI_API_KEY=your_openai_api_key
OPENAI_MODEL=gpt-4.1-mini

Optional overrides:

LANGGRAPH_API_URL=http://localhost:2024
VITE_LANGGRAPH_API_URL=http://localhost:2024
VITE_LANGGRAPH_ASSISTANT_ID=assistant-ui-claude
