Codex CLI 0.156.0-alpha.10

0.156.0-alpha.9→0.156.0-alpha.10·September 20, 2026 at 10:16 PM UTC

Alpha prerelease focused on a richer TUI transcript experience (selection, search, empty-state presentation) plus a new /warnings slash command.

Changelog

  • [new] Added the /warnings slash command for reviewing warning state from the TUI.
  • [new] Introduced a dedicated transcript view with search, text selection, disclosure controls, and footer/mutation support for clearer thread browsing.
  • [new] Added text selection support across the TUI for copying and working with conversation content more directly.
  • [new] Rebuilt empty-state presentation with a new animation path (replacing the previous ASCII animation) and clearer empty-state policy handling.
  • [new] Improved first-run and resume flows with startup draft input, startup presentation, and startup recovery handling.
  • [new] Added a shortcut overlay in the bottom pane so available keybindings are easier to discover.
  • [new] Added mouse handling in the chat composer and textarea, including layout work for the composer.
  • [changed] Reworked agent center navigation and rendering (replacing the previous agents overview render path) for clearer multi-agent browsing.
  • [changed] Expanded TUI analytics surfaces, including activity chart rendering, chrome, controls, and hints.
  • [changed] Expanded global and pager keymaps so more TUI actions can be bound consistently.
  • [changed] Refined chat input flow, owned-transcript handling, and warning surfaces in history/chat widgets.

Under the hood

  • Thread and agent APIs pick up additional typed payloads (including generated thread titles, thread usage queries, realtime voice listing, and agent registration responses).
  • GitHub-oriented models land for pull request and parent-repo metadata used by related integrations.
  • Auth and identity plumbing continues to evolve (including JWK set handling and executable/process identity details).
  • Hook handler metadata is broadened so prompt, command, MCP tool, and agent handlers are represented more uniformly.
  • Client event traffic shifts toward a client-message style notification path in place of the previous ack-oriented event.
  • Profile invocation and argument-info structures support richer launch/configuration wiring.
