解决了之前版本报告的 issues:https://bitbucket.org/pypy/pypy/issues 或者 IRC at #pypy。
新特性:
Add preliminary support for a new lightweight statistical profiler vmprof, which has been designed to accomodate profiling JITted code
Numpy:
Support for object dtype via a garbage collector hook
Support for .can_cast and .min_scalar_type as well as beginning a refactoring of the internal casting rules
Better support for subtypes, via the __array_interface__, __array_priority__, and __array_wrap__ methods (still a work-in-progress)
Better support for ndarray.flags
性能提升:
Improved IO performance of zlib and bz2 modules
We continue to improve the JIT’s optimizations. Our benchmark suite is now over 7 times faster than cpython
Slight improvement in frame>
Internal refactoring and cleanups leading to improved JIT performance
更多改进请看发行说明。
Cheers
The PyPy Team PyPy 是用Python实现的Python解释器。
PyPy是,Python开发者为了更好的Hack Python创建的项目。此外,PyPy比CPython是更加灵活,易于使用和试验,以制定具体的功能在不同情况的实现方法,可以很容易实施。 该项目的目标是,让PyPy比C实现的Python更为容易的适应各个项目和方便裁剪。
