Release 3.7.0.1 is a bug-fix only release based off 3.7.0, while release 3.7.1 has new 3.7 API compatible features in addition to all the same bug fixes.
Andrew F. Davis <
Detailed release notes follow.
Important new features:
GRC Bus Ports (Nicholas McCarthy)
Bus ports in the GNU Radio Companion (GRC) allow ganging block input
or output ports into a single port for display and connections. This
simplifies flowgraph entry when dealing with blocks that work with an
arbitrary number of streams.
