WhatsApp Beta for Windows Phone has updated to a new version 2.18.28. The update brings new “Group Description” feature.
All participants can view the group description (that’s public in case the group invite link has been shared with third parties) at the top of the Group Info Section.
You will be able to add up to 512 characters to the Group Description and it will be displayed to anyone invited to a group.
Unlike the last update which was hidden one this update is not hidden and publicly available. You can download the updated app from the link given below.
