Installers for Windows includes outdated OpenSSL version
The 3.3.4 RC1 released last October is shipped with OpenSSL 1.0.1g on Windows. As can be seen on this page, there are ~20 CVEs closed after 1.0.1.g.
It seems that Wt 3.3.4 will be released soon. I hope it won't be shipped with an outdated and insecure OpenSSL version.
