Skype for Business changelog:
If you are familiar with the Lync app for Windows Phone, you’ll notice a number of enhancements in the new app. The most noticeable differences right off the bat are the Skype for Business brand and UI, which is intuitive and familiar if you happen to use Skype in your personal communications. We’ve also revamped emoticons, which now offers over 100 emoticons to land your message visually.
We have improved how the app and the server handle conversation notifications. Once you’re notified of a new conversation on your phone, the other clients you have logged in won’t be able to grab the conversation and prevent you from responding on your phone.
We’ve also enhanced security with at-rest data encryption, so your conversation history and voicemail is encrypted by default.
And your most recent conversations are now synchronized across devices whether they took place on your PC, tablet or phone, as long as you’re running the latest server software. We’re working hard to enable that for Office 365 users as well, so stay tuned for more news to come.
