WhatsApp Updated to v2.12.194 today from v2.12.189, which means 5 updates within 24 hours.
Significant change is in this series of updates is the new custom notifications settings. The new setting can be found in a contact’s or group’s detail page just below the media box. The notification setting box includes options to mute chat as well and you can mute the chat for 8 hours, 1 week, or 1 year, as well as extensive custom notifications.
A new feature Mark as Unread is also added in this update, just tap and hold on any conversation and you’ll be able to mark it as unread, which switches its status to green but doesn’t affect the read messages status inside the chat or its chronological rank among your conversations. It could serve as a visual reminder when you want to get back to someone later. In new custom notification option users an easily customize options for tones, vibration length, popup notification, and others.
Also there are two new changes in app settings, firstly a Low data usage option for voice calls, useful when you’re on a limited or slow data plan. Second is a small hint to Google Drive backups.
However the new update for WhatsApp is yet to reach on Google Play Store of India, till then wait.
