If you've been having some issues with BlackBerry Link for the past few days like I have, you'll want to go ahead and check for updates. A new version is rolling out through the auto update process and new versions have been posted to the BlackBerry Website as well for download. The Mac version gets bumped into 184.108.40.206 while the Windows version will see a jump to 220.127.116.11.
The updates don't really bring a full change log with them as they simply show the same change log as the previous release, so it's a bit hard to say what's been fixed up aside from saying bugfixes. I can note though that BlackBerry Link is no longer hanging for me after several reboots, this was the problem I was seeing the past few days, so there's that. Spot anything else? Drop a note in the comments and let others know.
