Codex v0.143.0 (July 8) is the first stable release in the 0.143 series after 39+ alpha builds. Remote plugins are now enabled by default; system proxy is supported on macOS and Windows; Amazon Bedrock models with configurable reasoning effort are added; MCP tool handling is improved. Bug fixes cover Windows input handling, stale TUI prompts, and WebSocket request failures.

Why it matters

Enabling remote plugins by default and native proxy support lowers the deployment barrier for enterprise teams running Codex behind corporate network policies; reaching stable marks a production-readiness milestone after months of alpha.

Importance: 3/5

First stable release milestone for Codex 0.143.x; remote plugins on by default is a meaningful enterprise deployment improvement.
