Release Notes

New Features - GPT-6-Astra is now available in the model picker and Amazon Bedrock catalogs. (42879, 42619) - Experimental worktree support lets you create isolated checkouts for new or forked sessions using --worktree or /worktree, then browse and resume them. (42652, 43069, 43120, 43286) - Answer questions inline while Codex continues working, using suggested choices or custom text without losing your main draft. (42891, 42894, 42897) - Windows sessions can now share a background Codex server, with daemon lifecycle commands and managed updates. (42405, 42392) - Vim editing gains R replace mode with undo and dot-repeat, plus more reliable Escape handling in legacy terminals. (42194, 42584) - Copying responses preserves formatting in rich-text apps, and /copy can copy status output or individual session fields. (42847, 43055) Bug Fixes - Existing sessions pick up newly installed plugin tools and refresh skills and hooks after external plugin upgrades or rollbacks. (42284, 42593, 42990) - MCP connections coordinate OAuth token refreshes and surface login challenges when refresh fails, without automatically replaying rejected tool calls. (42413, 42552) - Startup avoids running workspace-controlled helpers before trust is established, and the macOS sandbox blocks terminal input injection. (42324, 42590) - Remote resume and fork operations preserve saved permissions; fresh sessions and forks respect server model defaults unless explicitly overridden. (43330, 43177, 43355) - Resuming a conversation open in another app now shows a read-only transcript with a retry option while preserving your draft. (43253) - Automatic approval reviews better preserve authorization context through compaction and reject approvals invalidated by new user instructions or answers. (42844, 42852, 43442) Documentation - Updated the bundled OpenAI Docs skill with GPT-6-Astra migration, compatibility, and prompting guidance. (42931) Chores - The deprecated codex mcp-server entry point is no longer available.
