Assets 2

This release is combination and transition from the previous year-and-quarter release tagging (e.g. OpenCPI-2017.Q2) to the more conventional semantic versioning (e.g. v1.4.0) that has been running in parallel. Thus the release tag is a combination of both to show the transition, but future releases will have completely conventional semantic versioning tags and releases. The next release will likely simply be v1.4.1 or v1.5.0.
