This release has been tested on the following platforms:

        Debian Buster / x86_64
        Ubuntu Bionic / x86_64 / qemu-x86_64
        Armbian Bionic / Orange Pi PC2 (armv8) 
        Raspbian Buster / Raspberry Pi B (armv7) (no Parity, no Monerod)
        Windows 10 Enterprise Eng. / MSYS2 / qemu-x86_64

and with the following coin daemon versions:

        Bitcoin Core 0.17.1, 0.19.0.1
        Bitcoin-ABC 0.21.0
        Litecoin Core 0.17.1
        Monerod 0.15.0.1
        Parity Ethereum 2.7.2*

        * Parity crashes on startup on some systems when in developer mode,
        causing the 'eth' test to fail.  This is a problem with Parity, not
        MMGen.  On cleanly installed systems, Parity and the 'eth' test run
        without issue on all tested platforms.

Altcoin address generation has been additionally tested using the following
tools as references:

        zcash-mini a2b35042 (https://github.com/FiloSottile/zcash-mini)
        pycoin 11f60a7c (https://github.com/richardkiss/pycoin)
        vanitygen-plus 22123128 (https://github.com/exploitagency/vanitygen-plus)
