Hi,
I tested the latest October 18 2026 zip file, and found that rtl_test does not detect the RTL-SDR Blog V4L.
But if I compile from source from the Osmocom rtl-sdr GitHub, I get working V4L support for Windows and Linux, so the source is working fine.
So it seems that the automatic builds are not working correctly and are using old code to build librtlsdr.dll and possibly everything else?
