Back then, WhatsApp was simpler. There were no disappearing messages, no Channels, no Communities, and no Avatars. The app was lightweight, often under 30MB, and flew on dual-core processors with 512MB of RAM.
This was the major cutoff. WhatsApp officially announced that it would no longer support any device running Android 4.4 (KitKat) or older. This wasn't just about new features; it was a fundamental end of service. After this date, you could not download the app from the Google Play Store on a KitKat device, nor could you install official updates. Eventually, the app itself stopped launching, blocking access to your messages and calls.
Modern WhatsApp uses advanced end-to-end encryption protocols that the outdated libraries in KitKat cannot support. whatsapp for android 4.4.2

Android 4.4.2 relies on an older version of the Bouncy Castle cryptography library and limited native support for modern cipher suites. While it supported AES and RSA, the integration of newer elliptic curve cryptography (ECC) standards required for the Signal Protocol (used by WhatsApp) required significant backporting via software libraries rather than native hardware acceleration.
