GNU Radio 3.8 talk at GRCon ‘16

GNU Radio series e.g. 3.7 are supported for about 2 years. This means that old and obsolete libraries are required, which can become frustrating as a new release is awaited (as we are for GR 3.8)

GR 3.8 is removing 10 lines of code for every 1 line of code added. Multi-year old bugs were never found due to sheer size of codebase.
