You can now pay a recurring fee of $0.99 per month to remove ads, and get a custom PIN for a separate monthly fee of $1.99.
Custom PINs must be between six and eight characters in length, are not case sensitive and can only include letters and numbers. Premium users also get a little badge on their avatar.
Group chats now support photo sharing. These images are displayed in-line and also saved to the Pictures section of each group, where you can like and comment on them.
On iOS, the app is adding TouchID support to allow you to lock private conversations.
