It goes without saying that it also works well under Windows 10 Mobile as well.
As best as I can tell, working from a load of different changelogs(!), here then is roughly what's been added to Whatsapp for Windows Phone 8.1 and Windows 10 Mobile this year, i.e. in the last six months:
- You can now share with your contacts photos and videos that disappear after 24 hours.
- Live Location: Participants in a chat will see your position in real time. The function shares the position for a selected duration (15 minutes, 1 hour or 8 hours) even when you are not using the app. You can stop sharing at any time.
- Group description: A short blurb found under group info that allows you to set the purpose, guidelines, or topics for the group. When a new person joins a group, the description will show up at the top of the chat.
- Admin controls: In group settings, there’s now a control that allows admins to restrict who can change the group’s subject, icon, and description.
- Group catch up: When you’ve been away from a group chat, quickly catch up on messages that mention or reply to you by tapping on a new @ button that appears at the bottom right corner of the chat.
- Participant search: Find anyone in a group by searching for participants on the group info page.
- Admins can now remove admin permissions of other group participants, and group creators can no longer be removed from the group they started.
- Introduced protection so users can’t be repeatedly added to groups they’ve left.
- Ability to switch between Audio and Video calls.
Not too shabby. I guess this could have been a 'Flow' story on AAWP, but Whatsapp is such a core app/service for so many people that I wanted to highlight its continued full support of Windows on phones.
Some screenshots by way of illustration (though I'm only a casual Whatsapp user, please do comment if I've misunderstood anything!):
All a bit confusing overall. It's great to see improvements coming each month, but unless I'm missing something the UI isn't actually surfacing all the new features. Comments and tips welcome!
