Today seems like a good day to update BBM to the latest version. The new 18.104.22.168 version is starting to propagate through App World and is currently available by going to blackberry.com/bbm as well. For some reason, this update is only available for OS 7.1, and since this is the first time a BBM update is made for a specific OS only, we're not entirely sure if it will be supported on 7.0 and below later.
The changes aren't huge so if you don't have OS 7.1, I wouldn't worry too much about it.
Change log for v22.214.171.124:
- Broadcast messages now appear in purple
- Improved layout for the Chinese Handwriting feature
- Added support for Finnish
