New Features
- Add conversation/thread fork endpoints in the protocol and app server so clients can branch a session into a new thread. (#8866)
- Expose requirements via
requirement/listso clients can readrequirements.tomland adjust agent-mode UX. (#8800) - Introduce metrics capabilities with additional counters for observability. (#8318, #8910)
- Add elevated sandbox onboarding with prompts for upgrade/degraded mode plus the
/elevate-sandboxcommand. (#8789) - Allow explicit skill invocations through v2 API user input. (#8864)
Bug Fixes
- Codex CLI subprocesses again inherit env vars like
LD_LIBRARY_PATH/DYLD_LIBRARY_PATHto avoid runtime issues. As explained in #8945, failure to pass along these environment variables to subprocesses that expect them (notably GPU-related ones), was causing 10x+ performance regressions! Special thanks to @johnzfitch for the detailed investigation and write-up in #8945. (#8951) /review <instructions>in TUI/TUI2 now launches the review flow instead of sending plain text. (#8823)- Patch approval “allow this session” now sticks for previously approved files. (#8451)
- Model upgrade prompt now appears even if the current model is hidden from the picker. (#8802)
- Windows paste handling now supports non-ASCII multiline input reliably. Special thanks to @occurrent laying the groundwork for this fix in #8021! (#8774)
- Git apply path parsing now handles quoted/escaped paths and
/dev/nullcorrectly to avoid misclassified changes. (#8824)
Documentation
- App-server README now documents skills support and usage. (#8853)
- Skill-creator docs clarify YAML frontmatter formatting and quoting rules. (#8610)
