This is the sevententh production release of PyCBC for use in LIGO's second observing run. This release has been tested against LALSuite with the hash: 539c8700af92eb6dd00e0e91b9dbaf5bae51f004 This release fixes two packaging bugs: That PyPi distribution of v1.7.6 was missing a file which causes installation of PyCBC using pip to fail.
