New Features - Realtime V2 can now stream background agent progress while work is still running and queue follow-up responses until the active response completes (17264, 17306) - Hook activity in the TUI is easier to scan, with live running hooks shown separately and completed hook output kept only when useful (17266) - Custom TUI status lines can include the renamed thread title (17187) - Code-mode tool declarations now include MCP outputSchema details so structured tool results are typed more precisely (17210) - SessionStart hooks can distinguish sessions created by /clear from fresh startup or resume sessions (17073) Bug Fixes - Fixed Windows elevated sandbox handling for split filesystem policies, including read-only carveouts under writable roots (14568) - Fixed sandbox permission handling for symlinked writable roots and carveouts, preventing failures in shell and applypatch workflows (15981) - Fixed codex --remote wss://... panics by installing the Rustls crypto provider before TLS websocket connections (17288) - Preserved tool search result ordering instead of alphabetically reordering results (17263) - Fixed live Stop-hook prompts so they appear immediately instead of only after thread history reloads (17189) - Fixed app-server MCP cleanup on disconnect so unsubscribed threads and resources are torn down correctly (17223) Documentation - Documented the elevated vs restricted-token Windows sandbox support split in the core README (14568) - Updated app-server protocol documentation for the new /clear SessionStart source (17073) Chores - Made rollout recording more reliable by retrying failed flushes and surfacing durability failures instead of dropping buffered items (17214) - Added analytics schemas and metadata wiring for compaction and Guardian review events (17155, 17055) - Improved Guardian follow-up efficiency by sending transcript deltas instead of repeatedly resending full history (17269) - Added stable Guardian review IDs across app-server events and internal approval state (17298) Changelog Full Changelog: https://github.com/openai/codex/compare/rust-v0.119.0...rust-v0.120.0 - 17268 remove windows gate that disables hooks @iceweasel-oai - 17267 Stop Realtime V2 response.done delegation @aibrahim-oai - 14568 fix: support split carveouts in windows elevated sandbox @viyatb-oai - 17263 preserve search results order in toolsearchoutput @sayan-oai - 17189 Emit live hook prompts before raw-event filtering @abhinav-oai - 17288 Install rustls provider for remote websocket client @etraut-openai - 16969 Option to Notify Workspace Owner When Usage Limit is Reached @richardopenai - 17278 Rename Realtime V2 tool to backgroundagent @aibrahim-oai - 17280 Extract realtime input task handlers @aibrahim-oai - 17249 adding parentthreadid in guardian @won-openai - 17264 Stream Realtime V2 background agent progress @aibrahim-oai - 17210 Add outputschema to code mode render @vivi - 16344 feat: move exec-server ownership @jif-oai - 17214 feat: make rollout recorder reliable against errors @jif-oai - 17223 fix: MCP leaks in app-server @jif-oai - 17338 feat: description multi-agent v2 @jif-oai - 17269 feat(guardian): send only transcript deltas on guardian followups @owenlin0 - 17306 Queue Realtime V2 response.create while active @aibrahim-oai - 17352 fix: main @jif-oai - 17363 Strengthen realtime backend delegation prompt @aibrahim-oai - 17155 [codex-analytics] add compaction analytics event @rhan-oai - 17187 Add thread title to configurable TUI status line @canvrno-oai - 17194 add parent-id to guardian context @won-openai - 17266 [codex] Improve hook status rendering @abhinav-oai - 17073 Support clear SessionStart source @abhinav-oai - 17298 fix(guardian, app-server): introduce guardian review ids @owenlin0 - 17391 Revert "Option to Notify Workspace Owner When Usage Limit is Reached" @shijie-oai - 17371 app-server: add pipelined config rpc regression test @euroelessar - 15981 fix(permissions): fix symlinked writable roots in sandbox permissions @viyatb-oai - 17055 feat(analytics): add guardian review event schema @owenlin0
