Codex CLI 0.146.0 (released 2026-07-29) adds session naming via /new and /clear, thread pinning and paginated thread forking, Agent Plugins manifest support with Amazon Bedrock and Claude Code marketplace compatibility, WebSocket connectivity between app-server and remote Code Mode hosts, and standalone web search for custom model providers.

Why it matters

Plugin manifest interoperability with Claude Code and Bedrock signals Codex CLI moving toward a shared agent-plugin ecosystem rather than a closed format.

Importance: 2/5

Minor-version update with real cross-agent plugin interoperability features, single-source official confirmation.
