Codex CLI 0.156.0-alpha.9

0.156.0-alpha.8→0.156.0-alpha.9·September 20, 2026 at 2:17 AM UTC

Patch alpha (0.156.0-alpha.8 → 0.156.0-alpha.9) focused on TUI structure and session/cloud env cleanup, with supporting protocol and config model tweaks.

Changelog

  • [changed] Custom prompt UI is reworked around a dedicated picker flow (including shared picker styling), instead of a single monolithic custom-prompt view.
  • [changed] Chat history gains a clearer MCP preview path so tool-related output is easier to scan in-session.
  • [changed] Transcript rendering is split into explicit layout and text handling for more reliable transcript display.
  • [new] Terminal hyperlink support is wired in so eligible paths and references can behave as links in supporting terminals.
  • [changed] Selection tabs land in the bottom pane for tighter multi-option navigation in place.
  • [changed] Session identity env handling is normalized to CODEX_SESSION_ID (replacing CODEX_SESSION_IDS).
  • [changed] Cloud-tasks internal override env is corrected to CODEX_CLOUD_TASKS_FORCE_INTERNAL (replacing the misspelled CODEX_CLOUD_TASKS_FORCE_INTERNALR).
  • [removed] The old activity-chart palette helper and turn-runtime chat widget path are dropped as part of the TUI cleanup.

Under the hood

  • App-server approval conversions move into their own TUI module so approval payloads map more cleanly into UI state.
  • Contrast helpers are centralized under a shared style module for more consistent readable chrome.
  • Client/event traffic picks up an explicit ack-style Codex event in place of the previous client message-chunk event naming.
  • Sandbox state args are modeled as a dedicated payload type; several unused or superseded config/API shapes (apps list summaries, profile invocation, thread usage query leftovers, and related register/JWK helpers) are pruned.
  • Hook handler configuration distinguishes agent vs MCP tool-hook styles more directly.
  • Process identity and remote-control connection status modeling is adjusted across Linux/macOS paths; filesystem path / glob representations and a few gateway OAuth delivery and handshake reject variants are realigned.
  • Login account params favor ChatGPT auth-token style setup over a plain API-key variant in the updated surface.
  • Workspace lockfile and version.json are bumped to 0.156.0-alpha.9 on the alpha channel.

Upgrade notes

  • If you set CODEX_SESSION_IDS or CODEX_CLOUD_TASKS_FORCE_INTERNALR, switch to CODEX_SESSION_ID and CODEX_CLOUD_TASKS_FORCE_INTERNAL respectively before relying on those overrides.
