Released 2026-09-08T19:32Z, goose v1.50.0 removes fast model routing (#11469) and the managed model registry from local inference (#11789), two features that had been doing automatic model selection on the user's behalf. Alongside that it adds GPT-6 Astra support and tool calling for goose-agent, and publishes the goose ACP client and acp binary as separate npm packages so other harnesses can speak Agent Client Protocol to it without pulling goose. The security fixes are of a piece: HTTPS required for Snowflake connections, CLI session naming bound to a trusted path, subagent platform guards enforced, and permission revocations preserved across managers.
