 - Pinned background sessions (`Ctrl+T` in `claude agents`) now stay alive when idle, are restarted in place to apply Claude Code updates, and are shed under memory pressure only after non-pinned sessions
 - Renamed `/simplify` to `/code-review`. It now reports correctness bugs at a chosen effort level (e.g., `/code-review high`); pass `--comment` to post findings as inline GitHub PR comments. The old cleanup-and-fix behavior has been removed
-- Hardened the REPL tool sandbox against prototype-pollution and thenable-based escapes
 - Improved auto-updater: retries transient network failures, reports specific error categories and OS error codes on failure, and shows the current version when an update fails
 - Improved diff rendering performance for large file edits
 - Prompt history no longer records consecutive duplicate entries — recalling a prompt with arrow-up and submitting it again won't add another copy
