Adobe has released an update to Lr CC today, version 1.0.1 and customers should be able to install this from the Apps tab in the Creative Cloud desktop application.
The update does not include any major new features but should help in the following cases:
-a crash that occasionally surfaces on Mac OS High Sierra
-some internal sync changes that cause less churn with Adobe servers
In summary, this quick update should result in better efficiency when using Lr CC.
