[Proposal] add gitmcp badge for simple LLM-accessible documentation ( #4502 )
...
[gitmcp.io](https://gitmcp.io/ ) provides easy access to the latest
langgraph docs through a remote, free, open-source MCP. It's supported
by all major clients (including the new claude.ai web client). It
enables two access points -
- Empower AI agents (e.g., Cursor) with live documentation context to
prevent hallucinations.
- Chat with the documentation in the browser via the embedded chat
This PR proposes adding a new badge to help users make the most of
Langgraph's documentation with GitMCP. The badge is
[customizable](https://github.com/idosal/git-mcp?tab=readme-ov-file#-gitmcp-badge ).
The count is a live count of users accessing Langgraph's documentation
through GitMCP.
Example:
[](https://gitmcp.io/langchain-ai/langgraph )
You can see a demo with Langgraph's GitHub pages at gitmcp.io.
Please let us know what you think :)

Fix AsyncPostgresStore._cursor row type ( #4623 )
...
`AsyncPostgresStore._cursor` is expected to yield
`AsyncCursor[DictRow]`. In the `else` branch the `row_factory` was not
defined, meaning that it would yield `AsyncCursor[TupleRow]` (default).
This resulted in an error in
[langgraph/store/postgres/aio.py#L249](https://github.com/langchain-ai/langgraph/blob/main/libs/checkpoint-postgres/langgraph/store/postgres/aio.py#L249 )
(`TypeError: tuple indices must be integers or slices, not str`).

Fix invalid channels error message ( #4357 )
...
# PR Summary
This small PR resolves the error formatting in
`libs/langgraph/langgraph/pregel/algo.py` so the `proc.channels` will be
evaluated in the message.
