Codex CLI 0.148.0-alpha.17

0.148.0-alpha.16→0.148.0-alpha.17·August 14, 2026 at 8:17 PM UTC

Alpha patch (0.148.0-alpha.17) focused on resume-picker transcript previews in the TUI, exec-server relay protocol work, and related session/API groundwork.

Changelog

  • [new] Resume picker can show a transcript preview so it is easier to identify the session you want to continue.
  • [changed] App-server session handling now tracks rollout history for richer resume and session continuity.
  • [changed] Collaborative waiting lifecycle is clearer with an explicit end-of-wait signal.
  • [changed] Client messaging events are consolidated around full message results instead of chunk-oriented client message events.
  • [removed] The delete_to_line_end editing/notification path is no longer present.

Under the hood

  • Exec-server relay traffic moves onto a dedicated v1 protobuf relay surface, replacing the older noise-relay message-framing path.
  • Multi-agent and model message payloads are expanded (including mode/role message shapes), and a Tools v2 payload shape is introduced for upcoming tool wiring.
  • Filesystem helper responses, project config, environment status, token-usage profile/daily-bucket types, and related app/integration response models are refined (including GitHub PR and Homebrew cask info shapes).
  • MCP server identity/matching and several login/account parameter variants are reworked as part of ongoing auth and connector cleanup.
  • Minor dependency trim (dropped an unused event-listener-strategy transitive).
