Codex CLI 0.148.0-alpha.2

0.148.0-alpha.1→0.148.0-alpha.2·August 7, 2026 at 10:17 AM UTC

Alpha patch: fork an existing session into a new one with codex exec fork, and export the TUI transcript with /export.

Changelog

  • [new] codex exec fork forks a previous session by id (UUID or thread name) into a new session, with an optional follow-up prompt (including stdin via -). Supports the usual exec knobs such as --image, --model, --output-schema, --output-last-message, config overrides, and JSONL output.
  • [new] /export slash command exports the current TUI transcript.
  • [changed] Shell completions (bash, fish, zsh) cover exec fork and its flags.

Under the hood

  • Exec-server picks up structured environment configuration, and local config loading is split out for clearer resolution paths.
  • Agent-identity auth can point at separate Auth API and JWKS bases via CODEX_AGENT_IDENTITY_* settings.
  • TUI turn handling is reworked for more reliable runtime behavior; optional rounded TUI chrome is gated by CODEX_TUI_ROUNDED.
  • Hook configuration gains an MCP-tool handler path alongside existing prompt hooks.
  • Session/thread and filesystem response payloads expand slightly (including unarchive notifications and directory/open results), and tool-registry TOML config is reshaped for richer definitions.
  • Token usage is modeled as an explicit profile for clearer accounting downstream.
