The SwiftKey folks have released a new version of the popular third-party keyboard that comes with support for thirteen new Indian languages bundled in, but it's all still tucked away in beta form. Users who download the 5.1 beta will get access to Assamese, Bengali, Gujarati, Kannada, Malayalam, Marathi, Oriya, Punjabi, Tamil, Telugu, Urdu, Nepali, and Sinhala (Nepali and Sinhala are not Indian languages but SwiftKey opted to lump them in because they belong to the same Indo-Aryan language family).
Chat clients limited to one-on-one conversation are going the way of the dodo. We've got numerous options for group messaging including: Facebook Messenger, WhatsApp, Google+ Messenger, Live Messenger, and we're even pretty sure Babel (or whatever it will be called) will join the list. Today, popular cross-platform chat app, Tango, steps up to match its competitors.
The additions to the interface are very straightforward. You can pick multiple people from your contact list to start a conversation and at any time add new people or leave the chat altogether from the participants screen.
