Hello (this is my first time here ),

I found this post (and this forum) looking for an official 64-bit Linux build of LibMPSSE.
The official download links at https://ftdichip.com/software-examples/mpsse-projects/libmpsse-spi-examples/ are still without it.

Has there been any progress with the mentioned beta version in the last two years? 

I was a reluctant to download the libs from here:
https://github.com/bithium/ftdi-mpsse/tree/master/lib/spi/linux/x86_64

Is there anything directly from FTDI?

Thanks!
