Full changelog
Highlights
- Auto mode is now generally available. #4957
- Added configurable Auto goal-criteria acceptance. #4940
- Improved Auto behavior by authorizing actions from active goal/rubric directives, avoiding redundant approval prompts, showing the enable notice only on first global enable, deduplicating classifier-unavailable transcript spam, logging underlying classifier failures, and reporting classifier timeout budgets. #5017 #4993 #5012 #5013 #5011 #5025
- Added Hooks v2 capability snapshots and session transcripts, and hardened Hooks v2 command execution. #4916 #4918 #4917
- Raised the agent recursion limit to 2000 and made it configurable. #4994
Improvements and fixes
- Let the rubric grader inspect working-directory files, show rubric grader defaults, and improved
/rubrichelp and empty-state messaging. #4835 #4966 #5015 - Unified goal activation signaling. #4980
- Made Version, Model, and CWD copyable in the Debug Console. #4975
- Improved
config getoutput when a key is missing. #4976 - Aborted YOLO launch on
Ctrl+C/Ctrl+Dand made the YOLO warning friendlier for new users. #4953 #4950 - Updated LangSmith handling: secret redaction is disabled by default,
/tracenow flags empty env overrides that shadow the LangSmith key, and the default US endpoint is no longer treated as a custom target. #4970 #4996 #5022 - Injected OpenAI
prompt_cache_keyfor any OpenAI-provider endpoint. #4995 - Improved tool and schema presentation: finished calls stay on the live tool-group line, first-party tool schemas now include field descriptions, and
web_search/fetch_urltool descriptions were trimmed. #4927 #5019 #5016 - Omitted
plugins/andconversation_history/from the/agentpicker. #4991 - Made selector modal backdrop dimming consistent. #4990
- Restored the
"Server log preserved at:"notice on exit. #4999 - Used the SDK pin as the effective editable version. #4949
