"BRING THE BLUE BACK": WHATSAPP ANNOUNCES APP REDESIGN, NOT EVERYONE IS PLEASED

Summary from the TLDR Design newsletter

Whatsapp's new layout isn't a radical departure - search is more prominent at the top of the app. Below it, tabs let you quickly access unread messages and groups, and on the bottom, a row of icons lets users access Chats, Updates, Communities, and other features. However, WhatsApp users on iOS have noticed a significant visual change: the predominant color accent on everything is now green instead of blue.
