該版本值得關注的改進有：
-
The past months have seen pypy mature and grow, as rpython becomes the goto solution for writing fast dynamic language interpreters. Our separation of Rpython from the python interpreter PyPy is now much clearer in thePyPy documentation and we now have seperate RPython documentation. Tell us what still isn’t clear, or even better help us improve the documentation.
</li> </ul>-
We merged version 2.7.9 of python’s stdlib. From the python release notice:
</li>-
The entirety of Python 3.4’s ssl module has been backported. See PEP 466 for justification.
</li> -
HTTPS certificate validation using the system’s certificate store is now enabled by default. See PEP 476 for details.
</li> -
SSLv3 has been disabled by default in httplib and its reverse dependencies due to the POODLE attack.
</li> -
The ensurepip module has been backported, which provides the pip package manager in every Python 2.7 installation. See PEP 477.
</li> </ul> -
The garbage collector now ignores parts of the stack which did not change since the last collection, another performance boost
</li> </ul>-
errno and LastError are saved around cffi calls so things like pdb will not overwrite it
</li> </ul>-
We continue to asymptotically approach a score of 7 times faster than cpython on our benchmark suite, we now rank 6.98 on latest runs
</li> -
Issues reported with our previous release were resolved after reports from users on our issue tracker at https://bitbucket.org/pypy/pypy/issues or on IRC at #pypy.
