The following extract from https://www.apachefriends.org/blog/new_xampp_20160512.html
Xampp 5.5.35 / 5.6.21 / 7.0.6
Updated PHP to 5.5.35 / 5.6.21 / 7.0.6
Updated OpenSSL to 1.0.2h for OS X and Linux
There is no mention that OpenSSL is updated to 1.0.2h for Windows version.
Also, upon download the portable version of xampp 5.6.21 to check the OpenSSL version, it is also not 1.0.2h. It is still 1.0.2d.
May I know when will OpenSSL be updated to 1.0.2h for Windows version?
Also, are there any other ways to update the OpenSSL to 1.0.2h for Xampp?
