WhatsApp for Windows Phone has updated to version 184.108.40.206. However there is no change log available, assuming bug fixes and performance improvements.
However, last update for WhatsApp brings some new features and performance improvements:
- Improved search lets you instantly find messages, chats, and contacts. This may take a few days to show up after you update the app.
- Support for in-app notification sounds
Thanks Ayush for the Tip !
