WhatsApp preparing new Silent and Vacation modes for Android and iOS apps
Vacation Mode is still in development and is based on the Silent Mode. When it's enabled, Vacation Mode will prevent archived chat sessions from becoming active again once a new message is received.
Finally, Linked Accounts will allow users to link their Instagram and WhatsApp accounts. However, we still don't know what's the purpose of this feature but it may allow you to recover your Facebook/Instagram account using WhatsApp.
All the new features uncovered today are expected to be introduced on both the Android and iOS platforms, but desktop users will certainly get their benefits as well.
