LangChain's langgraph-cli 0.4.34 is now listed as the latest release on GitHub, following 0.4.33. Its one listed feature adds a --json option to the deploy listeners list command.

The langgraph-cli 0.4.34 release was published through GitHub Actions on 13 October and follows the 0.4.33 release. The changes listed on the release page are a version bump commit and a feature that adds --json to the deploy listeners list command.

The release page does not describe the output format or give further details on the new option. It lists two assets, but their contents are not shown in the text available.

## Why it matters if you build agents

If your scripts read the output of the deploy listeners list command, the new --json flag offers a machine-readable format in place of parsing plain text. Check the release page for details before changing any parsing code that depends on that output.
