Why are you still using so ancient libs? The current actual versions are openssl-1.1.1l, boost-1.76.0, miniupnpc-2.2.2.
Thank you for the question...
You can use newer libs in your personal builds, we plan to update them in the next release... Here you can see what we are working at the moment... https://github.com/AKKPP
Unfortunately, my openssl patch for 1.2.1 is no longer sufficient, so maybe I wait for the next release.
The openssl version used is from Dec. 2019

Also available is the 1.1.1 series which is our Long Term Support (LTS) version, supported until 11th September 2023. All older versions (including 1.1.0, 1.0.2, 1.0.0 and 0.9.8 ) are now out of support and should not be used. Users of these older versions are encouraged to upgrade to 3.0 or 1.1.1 as soon as possible. Extended support for 1.0.2 to gain access to security fixes for that version is available.
