latest released version not available in terraform registry

[charltonstanley]

At the time of writing, 2.1.7 is tagged as the latest release on this repository, however terraform reports that the latest available is 2.1.5. Can this be fixed so that I can pull straight from the registry instead of from github? Thanks in advance.
