+\b0  This variant of Python 3.6 now includes its own private copy of OpenSSL 1.0.2.  Unlike previous releases, the deprecated Apple-supplied OpenSSL libraries are no longer used.  This also means that the trust certificates in system and user keychains managed by the

-\i 64-bit/32-bit 10.6+ python.org variant
-\i0  continues to be dynamically linked with Apple's OpenSSL 0.9.8 since it was felt that the loss of the system-provided certificates and management tools outweighs the additional security features provided by newer versions of OpenSSL.  This will change prior to the beta releases of 3.6.0 as Apple has deprecated use of the system-supplied OpenSSL libraries.  If you do need features from newer versions of OpenSSL, there are third-party OpenSSL wrapper packages available through
