A new release for Mac OS X is now available ( version 20140814.3 ) which fixes issues preventing CUPS Cloud Print from working on Mac OS X Yosemite (10.10).
These were only changes relevant to the Mac OS X package, so there are no Linux packages for this release.
Installation instructions, as always are here.
- Fix: Now works on Mac OS X 10.10 ( Yosemite )
- Change: Moved Mac OS X Install dir from /usr/local/share/cloudprint-cups to /usr/share/cloudprint-cups
