I like to introduce sane defaults for SSLContext options and ciphers: Changed in version 3.6: The context is created with more secure default values. PROTOCOL_TLS is the default protocol. The options OP_NO_COMPRESSION, OP_CIPHER_SERVER_PREFERENCE, OP_SINGLE_DH_USE, OP_SINGLE_ECDH_USE, OP_NO_SSLv2 (except for PROTOCOL_SSLv2), and OP_NO_SSLv3 (except for PROTOCOL_SSLv3) are set by default. The initial cipher suite list contains only HIGH ciphers, no NULL ciphers and MD5 ciphers (except for PROTOCOL_SSLv2). |

+1 from me for a model where ssl.get_default_context() can change in maintenance releases, while the ssl.SSLContext defaults get updated for feature releases. |

I'm planning to remove PROTOCOL_TLS again and replace it with something more sensible. |

3.6 and master are looking good. Should I backport the fix to 2.7, too? |
