OpenAI's developer account announced Plugin Extensions for ChatGPT: developers can now build interactive panels, file viewers, and a sidebar home for their plugins, get clearer review feedback, and use the proposed MCP Events spec so events in connected apps can trigger automations inside ChatGPT. It upgrades plugins from content displays into full interactive apps embedded in the ChatGPT UI.
