Codex CLI 0.158.0 adds MCP OAuth client secrets and transparent image output
Codex 0.158.0 (stable) can connect to MCP servers that require a pre-registered OAuth client secret, and can generate images with a transparent background. It also protects the exec-server WebSocket with a bearer token and adds select-to-copy and right-click paste in the full-screen TUI. It fixes several Windows and Linux sandbox issues.
