The latest version (2.80) of the new RealSense SDK 2.0 is now available for download. Among the new features are ROS support, preliminary node.js integration and also a Depth Quality Tool that can be run as a pre-made executable
Please also note that in 2.80, the names of some of the API commands have also been changed. For example, rs2_stop_pipeline and rs2_start_pipeline are now rs2_pipeline_stop and rs2_pipeline_start (these two changes in particular make the commands fit neatly within the naming convention of the rs2_pipeline class). See the 'API Changes' link in the release notes (below) for the full list of changes.
