What's new in PyPy 2.0

Split rpython and pypy into seperate directories

Callbacks from C are now better JITted

Implement __lenght_hint__ according to PEP 424

Long double support for numpypy

Since r_longdouble support is missing, disable all longdouble and derivative dtypes using ENABLED_LONG_DOUBLE = False

Convert real, imag from ufuncs to views. This involves the beginning of view() functionality

Adds indexing by scalar, adds int conversion from scalar and single element array, fixes compress, indexing by an array with a smaller shape and the indexed object.

Allow concatenation of str and numeric arrays

Improved RPython typing

Rudimentary support for bytearray in RPython

Fix a bug which caused cffi to return the wrong result when calling a C function which calls a Python callback which forces the frames

JIT optimizations which make cffi calls even faster, by removing the need to allocate a temporary buffer where to store the arguments.

Improve documents and straighten out links

Inline the fast path of newarray in the assembler. Disabled on ARM until we fix issues.

Allow dynamic loading of a (Reflex) backend that implements the C-API needed to provide reflection information

Fixed the interaction between two internal tools for controlling the JIT.

Better optimized certain types of frame accesses in the JIT, particularly around exceptions that escape the function they were raised in.

Some missing attributes from ndarrays

Consolidated the lib_pypy/pypy_test and pypy/module/test_lib_pypy tests into one directory for reduced confusion and so they all run nightly.

Add "__pypy__.thread.signals_enabled", a context manager. Can be used in a non-main thread to enable the processing of signal handlers in that thread.

Support enumerate() over rstr types.

Cleanup _numpypy and numpypy namespaces to more closely resemble numpy.

Random cleanups to hide FlowObjSpace from public view.

Moves optimized JIT frames from stack to heap. As a side effect it enables stackless to work well with the JIT on PyPy. Also removes a bunch of code from the GC which fixes cannot find gc roots.

Documentation fixes after going through the docs at PyCon 2013 sprint.
