Codex CLI 0.149.0-alpha.7

0.149.0-alpha.4→0.149.0-alpha.7·August 20, 2026 at 8:16 PM UTC

Prerelease 0.149.0-alpha.7 on the 0.149.0 alpha line — small internal follow-ups for exec/TUI event handling, collaboration signaling, and configuration/requirements modeling.

Changelog

  • [new] Exec can process session events into JSONL-oriented output, making machine-readable run logs easier to consume downstream.
  • [new] The TUI keeps thread-related events in a dedicated path so timeline updates stay consistent as the session progresses.
  • [new] Collaboration sessions emit a clear end-of-wait signal when a collab wait completes.
  • [changed] Hook configuration distinguishes command-style and prompt-style handlers more cleanly.
  • [changed] Config and policy requirement models (including Guardian-related settings, managed hooks, and related TOML shapes) were extended to carry a fuller set of constraints.
  • [changed] Skills-related responses now cover migration/write flows more explicitly.
  • [changed] Thread fork responses and tool “request user input” payloads were reshaped for clearer client handling.
  • [changed] Filesystem helper payloads (for example create-directory / canonicalize-style responses) were tightened.
  • [removed] The delete_to_line_end event path is no longer part of the event set.
  • [removed] Several older app/task listing and background-terminal thread payload shapes were dropped in favor of the updated models.

Under the hood

  • Exec gained a dedicated JSONL event-processor path; the TUI added focused thread-event handling.
  • Remote code-mode session command-driver code was removed as that connection path was simplified.
  • Dependency footprint shrank slightly (unused crates dropped).
  • Sandbox/network and exec-server related environment knobs were adjusted; prefer current names if you wire automation to those variables.
  • OpenTelemetry exporter and handshake/capability rejection enums were refined as part of protocol cleanup.
  • Assorted internal request/response types (remote plugins, PR metadata helpers, token-usage profiling, patch approval) were added or resized ahead of follow-on work.
