LangGraph CLI 0.4.35 adds private registry deploys and keeps failed build logs

LangChain's langgraph-cli 0.4.35 was released on GitHub on 14 October. The headline addition is --image-pull-secret, a flag for deploying through a private registry. The release also logs in with the registry username that the control plane returns.

A fix now preserves build logs when a deployment fails, so developers can see what went wrong in a failed build. The changelog also includes a dependency bump that moves handlebars from 4.7.9 to 4.7.10 in the CLI's js-examples directory.

Compared with cli==0.4.34, the release contains three feature and fix changes plus that dependency update. The release notes do not describe any breaking changes.

Teams deploying LangGraph agents from a private container registry can now pass a pull secret through the CLI. Check the new login behavior before upgrading if your deployments depend on the registry username. Failed builds now keep their logs, which makes them easier to debug.
