With the latest update, version 2.18.70, WhatsApp has significantly improved group moderation. Admins can now specify whether all participants or only they themselves can write messages in the group.
Here's how it works:
First, go to “Group information” and then tap on “Group settings”. Here, click on “Send messages” and then choose between “all participants” and “admins only”.
According to WhatsApp, the new group feature will be available to all users worldwide with the latest version. Groups with organizational content will certainly benefit from this.

Another new feature is the ability to automatically inform your contacts about a phone number change via WhatsApp.
It works like this:
Settings -> Account -> Change number – once you have set a new phone number, you can now select whether and which contacts should be notified. Here you can now select individual people and/or entire groups.
