Added
- Add /permissions to switch between approval modes.
- ACP mode supports closing sessions with the closeSession request.
Improved
- New sandbox setting
allowDevToolCaches(on by default): grants sandboxed builds access to toolchain caches, registries, and installs so builds work without extra setup. Set false to opt out. - Honor explicit GitHub MCP toolset/tool config: keep gh-overlap tools and stop steering to the gh CLI when you opt in
- Warn on startup about unknown top-level keys in user settings.json (e.g. a misspelled setting) instead of silently ignoring them
- Shell completion for --model now suggests auto and supported model names
- Render long session transcripts progressively to keep scrolling responsive
- Resuming a long session is dramatically faster and far lighter on memory, because its history is now read once at startup (in parallel, across CPU cores) instead of being re-read in full for every check the CLI runs before it can paint. In our benchmark a 230MB, 74k-event transcript came back in well under a second instead of about ten, at roughly a quarter of the peak memory; the exact gain depends on your machine's core count and disk
Fixed
- Ctrl+Q now enqueues the highlighted mid-text skill completion instead of the partial token
- Switching sessions no longer restarts MCP servers or rebuilds hook state, so a turn running in another session is never halted with a stale-hook error
- Refresh deferred MCP tools after OAuth authentication
Removed
- The /allow-all auto safety-judge model is no longer user-configurable; the judge model is now selected automatically.
