What this post added

This post details the development of Facebook Messenger for Windows, a desktop application that delivers notifications and chat messages. It highlights the use of HTML and JavaScript for client-side rendering and application logic, allowing for server-side updates. For reliable message delivery, MQTT was adopted as the real-time push channel, similar to the mobile Messenger apps.
