https://bugs.python.org/issue26470 updated the ssl and hashlib modules in 2.7 and 3.5+ to be compatible with OpenSSL 1.1.0.

However, it's currently unclear what the *minimum* versions actually are for platforms that want to drop support for OpenSSL 1.0.x, and it's particularly unclear in 2.7, as that lacks the deprecation warning for OpenSSL 0.9.8, 1.0.0 and 1.0.1 that was introduced in Python 3.6.

This doesn't rise to the level of something to be documented as a new feature in the 2.7 What's New, but I think a version changed note in the opening section of the `ssl` module documentation would be appropriate:

2.7 branch:

    .. versionchanged: 2.7.13
       Updated to support linking with OpenSSL 1.1.0

3.6 and master branches (immediately before the 3.6 deprecation notice):

    .. versionchanged: 3.5.3
       Updated to support linking with OpenSSL 1.1.0
