Release Notes

New Features - Added an experimental, feature-gated JavaScript REPL runtime (jsrepl) that can persist state across tool calls, with optional runtime path overrides. (10674) - Added support for multiple simultaneous rate limits across the protocol, backend client, and TUI status surfaces. (11260) - Reintroduced app-server websocket transport with a split inbound/outbound architecture, plus connection-aware thread resume subscriptions. (11370, 11474) - Added memory management slash commands in the TUI (/mupdate, /mdrop) and expanded memory-read/metrics plumbing. (11569, 11459, 11593) - Enabled Apps SDK apps in ChatGPT connector handling. (11486) - Promoted sandbox capabilities on both Linux and Windows, and introduced a new ReadOnlyAccess policy shape for configurable read access. (11381, 11341, 11387) Bug Fixes - Fixed websocket incremental output duplication, prevented appends after response.completed, and treated response.incomplete as an error path. (11383, 11402, 11558) - Improved websocket session stability by continuing ping handling when idle and suppressing noisy first-retry errors during quick reconnects. (11413, 11548) - Fixed stale thread entries by dropping missing rollout files and cleaning stale DB metadata during thread listing. (11572) - Fixed Windows multi-line paste reliability in terminals (especially VS Code integrated terminal) by increasing paste burst timing tolerance. (9348) - Fixed incorrect inheritance of limitname when merging partial rate-limit updates. (11557) - Reduced repeated skill parse-error spam during active edits by increasing file-watcher debounce from 1s to 10s. (11494) Documentation - Added JS REPL documentation and config/schema guidance for enabling and configuring the feature. (10674) - Updated app-server websocket transport documentation in the app-server README. (11370) Chores - Split codex-common into focused codex-utils- crates to simplify dependency boundaries across Rust workspace components. (11422) - Improved Rust release pipeline throughput and reliability for Windows and musl targets, including parallel Windows builds and musl link fixes. (11488, 11500, 11556) - Prevented GitHub release asset upload collisions by excluding duplicate cargo-timing.html artifacts.
