We are very close to the WWDC 2017 that will show iOS 11 to the public.
iOS 10 brought many new features in WhatsApp and developers will continue to add new features compatible with iOS 10+: it will be the turn of Rich Notifications.
What’s new (@WABetaInfo changelog):
Main changes and improvements for actual features:
WhatsApp is improving the status feature, that soon will allow to share text statues.
WhatsApp Albums: this is the name of the new feature that WhatsApp is developing.
Thanks to albums, you will be able to share multiple photos at once (recently Instagram introduced the same feature for its app).
To create an album, you have to share/receive 4+ photos.
WhatsApp will add stickers in the app soon: this is the last news spotted in the iOS version, that shows a new redesign for sending GIFs and, finally, stickers.
As shown here, WhatsApp is going to redesign the GIFs picker, making it very similar to Android and Windows Phone.
