Release Notes

New Features - Running direct shell commands no longer interrupts an in-flight turn; commands can execute concurrently when a turn is active. (10513) - Added /statusline to configure which metadata appears in the TUI footer interactively. (10546) - The TUI resume picker can now toggle sort order between creation time and last-updated time with an in-picker mode indicator. (10752) - App-server clients now get dedicated APIs for steering active turns, listing experimental features, resuming agents, and opting out of specific notifications. (10721, 10821, 10903, 11319) - Enterprise/admin requirements can now restrict web search modes and define network constraints through requirements.toml. (10964, 10958) - Image attachments now accept GIF and WebP inputs in addition to existing formats. (11237) - Enable snapshotting of the shell environment and rc files (11172) Bug Fixes - Fixed a Windows startup issue where buffered keypresses could cause the TUI sign-in flow to exit immediately. (10729) - Required MCP servers now fail fast during start/resume flows instead of continuing in a broken state. (10902) - Fixed a file-watcher bug that emitted spurious skills reload events and could generate very large log files. (11217) - Improved TUI input reliability: long option labels wrap correctly, Tab submits in steer mode when idle, history recall keeps cursor placement consistent, and stashed drafts restore image placeholders correctly. (11123, 10035, 11295, 9040) - Fixed model-modality edge cases by surfacing clearer viewimage errors on text-only models and stripping unsupported image history during model switches. (11336, 11349) - Reduced false approval mismatches for wrapped/heredoc shell commands and guarded against empty command lists in exec policy evaluation. (10941, 11397) Documentation - Expanded app-server docs and protocol references for turn/steer, experimental-feature discovery, resumeagent, notification opt-outs, and null developerinstructions normalization. (10721, 10821, 10903, 10983, 11319) - Updated TUI composer docs to reflect draft/image restoration, steer-mode Tab submit behavior, and history-navigation cursor semantics. (9040, 10035, 11295) Chores - Reworked npm release packaging so platform-specific binaries are distributed via @openai/codex dist-tags, reducing package-size pressure while preserving platform-specific installs (including @alpha). (11318, 11339) - Pulled in a security-driven dependency update for time (RUSTSEC-2026-0009).
