Codex 0.147.0 adds portable Agent Plugins with search across local, personal, workspace, and remote catalogs. Conversations now organize into persistent, manually ordered sections for easier browsing of long transcripts. The new --approve-for-me flag enables automatic approval reviews. You can import skills from Cursor and synchronize changes to imported conversations without duplicates. Support for the MCP 2026-07-28 protocol includes paginated discovery, multi-round requests, and non-blocking server startup.
