New Features

  • Open /config to search preferences across categories, change supported settings immediately, and see which changes require a restart.
  • Send a follow-up while Codex is responding to steer it immediately. Interrupting a turn also stops active Code Mode cells and their nested tool calls.
  • Configure a leader key in /keymap. The default is Ctrl+X, shortcut hints stay open until you choose or cancel, and voice mute moves to F9.
  • Restart a managed background server from /daemon. Codex warns about work the restart could interrupt, then reconnects automatically.
  • Codex can run independent read-only tools in parallel, including skill, memory, and conversation-history lookups.
  • Daybreak is enabled by default for eligible accounts. codex exec can also select it with an OpenAI API key when the server offers access.

Bug Fixes

  • Resuming a saved thread restores its permissions and network approvals, while respecting explicit overrides and current managed policy.
  • The network proxy now checks permission before a DNS lookup, rejects duplicate Host headers, and prevents credential aliases from bypassing inspection hooks.
  • Return to an existing side conversation with /side after switching threads. Answers to pending prompts also go back to the thread that asked.
  • On Windows, Ctrl+V and Shift+Insert paste text as well as images. On WSL, repeated pastes reuse the clipboard reader, and copy attempts time out instead of hanging.
  • Local commands finish promptly when a child keeps an output pipe open. Remote commands preserve late-arriving output so the final poll can still collect it.
  • codex exec no longer prints the same file diff again after an unrelated command.

Documentation

  • Updated the bundled OpenAI Docs guidance for migrations to the GPT-6 family, including model-specific reasoning, tool use, and data residency considerations.
  • Clarified how the Linux sandbox uses bubblewrap for filesystem isolation and seccomp for syscall filtering.

Chores

  • Codex now uses its standard shell executor and no longer bundles a patched zsh. Configurations using the retired shell flags receive a migration notice.
  • Reduced Linux and macOS release package size by stripping symbols from packaged binaries while preserving them in the original build outputs.
