Ably CLI Release V1.0.0
NEW PRODUCT
Version 1.0.0 of the Ably CLI has been released, marking the first stable major version of @ably/cli. For anyone wiring the CLI into automation or AI agents, long-running commands now emit a structured JSON envelope with status and completed signals. Agents can tell exactly when a connection is live, a stream is flowing, or a command has finished. No more scraping log lines or guessing at exit timing. When a command fails, errors include a hint field that suggests the next step. The hint usually names a specific command to run resulting in agents that can self-heal in fewer turns, without a human in the loop.

The release also includes various API and type improvements around the Tree/View separation and associated React hooks.
