OpenAI Codex Changelog·medium signal
OpenAI's June 2026 Codex updates introduce Sites in preview — letting users create, save, deploy, and inspect websites, dashboards, internal tools, and web apps hosted by OpenAI directly from the Codex app. Codex also gained Computer Use on Windows, allowing it to see, click, and type in Windows applications while testing and debugging; the Bedrock catalog was refreshed to include GPT-5.5.
