Full changelog
What's changed
- Added
sandbox.credentialssetting to block sandboxed commands from reading credential files and secret environment variables - Added org-configured model restrictions to the model picker,
--model,/model, andANTHROPIC_MODEL, with a "restricted by your organization's settings" message when a restricted model is selected - Added mouse click support to select menus (permission prompts,
/model,/config, etc.) in fullscreen mode - Fixed
--resumefailing with "No conversation found" when the original-prun produced no model turns - Fixed
--json-schemaand workflowagent({schema})structured output: the model can no longer re-callStructuredOutputindefinitely after a successful call, and follow-up turns now reliably return structured output - Fixed remote MCP tool calls that hang with no response for 5 minutes — they now abort with an error instead of blocking indefinitely (override with

- Fixed leaked agent worktree registrations: locked
