Update Sep 9, 2026 tracked by Updatify

0.154.0

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. (#42993)
