Many people are asking me more details about the Facebook option, privacy for Facebook and ETA.
In this pastebin I wrote all information about the Facebook option (I updated it now, adding more new information).
It's very important to read it if you care about your privacy.
Please, expand this.

WhatsApp added support for recognizing spam calls in recent WhatsApp beta for Android versions.
Before it recognized spam messages only.

If you will enter in a WhatsApp public group using a invite link and an administration will delete you, you will not be able to access to that group again.

Si se expulsa a un miembro de un grupo, éste no podrá volver a entrar mediante enlace.

After December 31, 2016, WhatsApp will drop Android 2.1, Blackberry and Symbian support. This is a good news for iOS users, because WhatsApp will have more time to work on the iOS version.

Finally it is happening.. GIF support is coming to WhatsApp!

Note: actually seems that WhatsApp for iOS recognizes GIFs only if you send a link that contains one (unfortunately this is a hidden feature that I have not still enabled, so there aren't screenshots at the moment), but this is the first 2.16.7 beta, probably WhatsApp will add in next 2.16.7 beta the possibility to share GIF directly from the camera roll.
Remember that the 2.16.7 version will be a major release.
Recently you saw many WhatsApp update with the "Bug fixes" changelog: probably they were internally working on GIF support and general improvements before to put them in a beta.
Surely GIF support will be added in Android and WP too later.
Probably 2.16.7 will be the version that WhatsApp will enable video calls (because they added so many improvements for them): if it is a major release, probably we will be able to see Stickers and Quoted messages feature enabled too.

News:
We learned that WhatsApp will be ending support for its application on the following mobile platforms:
• BlackBerry, including BlackBerry 10
• Nokia S40
• Nokia Symbian S60
• Android 2.1 and Android 2.2
• Windows Phone 7.1

But in WhatsApp for iOS 2.16.7.1 beta I found this hidden string:
“Unfortunately, after December 31, 2016, you won't be able to use WhatsApp on this phone as WhatsApp will no longer support it.”
WhatsApp already added this string in Android, Blackberry, Nokia and Windows Phone app, but in the first 2.16.7 beta they added this in iOS too.
But why did WhatsApp add this string in the iOS app if they will be ending support for other OS?
Probably they will be ending support for iOS 6 too, this is the only reason because WhatsApp also added that in the iOS app.

GIF support unlocked in WhatsApp beta for iOS 2.16.7.35. 😀

WhatsApp 2.16.7 beta for iOS version has a very secret killer feature that developers worked on so much.
This feature should work using some gestures and should improve the communication method, like Quick Reply did.
When there will be news, I will alert you.

What features would you add in this list?
Mention @WABetaInfo on Twitter and I hope WhatsApp will read it!

News:
I wrote that WhatsApp is working on a secret killer feature that I'm studying to understand what it is, but after other investigations, I discover that WhatsApp for iOS 2.16.7.35 has another good secret feature.
It's a very important feature, and I will announce it in next days, when it will be ultimate .
*another news will shock the web, after the GIF feature* 😀

News:
The killer feature apparently has something to do with bubbles, replies and gestures.

News:
WhatsApp is enabling quoted messages.
Download latest WhatsApp version (iOS and Android).
If you haven't this feature, probably reinstalling WhatsApp will fix it.

Let me know on Twitter if WhatsApp enabled Quoted messages feature for you.
