* Fix Python 3.4 incompatibilities (added back to the CI) - by :user:`gaborbernat`. (`#1963 `_)
* For activation scripts always use UNIX line endings (unless it's BATCH shell related) - by :user:`saytosid`. (`#1818 `_)

* Fix a bug that reading and writing on the same file may cause race on multiple processes. (`#1938 `_)
* Provide correct path for bash activator in cygwin or msys2 - by :user:`danyeaw`. (`#1940 `_)

* pth files were not processed on CPython2 if $PYTHONPATH was pointing to site-packages/ - by :user:`navytux`. (`#1959 `_) (`#1960 `_)
* Fix test suite failing if run from system Python - by :user:`gaborbernat`. (`#1882 `_)
* Provide ``setup_logging`` flag to python API so that users can bypass logging handling if their application already
* performs this - by :user:`gaborbernat`. (`#1896 `_)

+ fallback to unverified context when querying the PyPi for release date,
+ stop downloading wheels once we reach the embedded version, by :user:`gaborbernat`. (`#1883 `_)
