Version 2.6 makes BBM ready for Android 5.0, but don't get too excited. There's no big redesign here. The app still looks as Gingerbread as ever, it just now explicitly supports devices running the latest version of Google's mobile operating system.
That's not to say that the update is without visual changes. If you turn your phone sideways, the interface will now rotate to landscape mode in order to accommodate you.
Other features new to BBM users include the ability to share stickers in a group chat, set longer limits on timed messages (up to 60 seconds), share multiple pictures or attachments at the same time, and see when someone has received or viewed your photos.
Here's the changelog.
- Support for Android 5.0 Lollipop
- Send stickers in group chats!
- See when a contact has received and viewed your sent pictures.
- Timed pictures and messages can now be viewed multiple times until the timer expires
- Added a new 60 second timer option
- Landscape mode
- Add a photo or attachment from your SD card
