Codex CLI 0.147.0, released August 7, 2026, adds portable Agent Plugins installable from local, personal, workspace, or remote catalogs, persistent manually-ordered conversation sections, an --approve-for-me auto-approval flag, and support for the MCP 2026-07-28 protocol revision.

Why it matters

Portable plugins and MCP 2026-07-28 support push Codex CLI toward the same extensibility model competitors like Claude Code and OpenCode are building around.

Importance: 2/5

Minor-version feature release with real new capabilities (plugins, MCP support).
