Before the update, I was running the Hackrf in GQRX on a Raspberry Pi 3B.

Input rate was 1 Msps, I could only run narrow fm, and I could not run DSP and use my mouse at the same time.  In other words, performance was all but unusable...

After the update, I can now run 1.5 Msps, my mouse functions, and Wide fm is not great, but it is not overloading the cpu any longer.  In other words, useability increased by a factor of 10, at least!

Thank you very much to the development team that made this happen!
