- Update to version 0.20:
* Support for CPython 3.4.
* Support for calling C++ template functions.
* yield is supported in finally clauses.
* The C code generated for finally blocks is duplicated for each exit
case to allow for better optimisations by the C compiler.
* Cython tries to undo the Python optimisationism of assigning a bound
method to a local variable when it can generate better code for the
direct call.
* Constant Python float values are cached.
* String equality comparisons can use faster type specific code in
more cases than before.
* String/Unicode formatting using the '%' operator uses a faster
C-API call.
* bytearray has become a known type and supports coercion from and
to C strings. Indexing, slicing and decoding is optimised. Note that
this may have an impact on existing code due to type inference.
* Using cdef basestring stringvar and function arguments typed as
basestring is now meaningful and allows assigning exactly
str and unicode objects, but no subtypes of these types.
* Support for the __debug__ builtin.
* Assertions in Cython compiled modules are disabled if the running
Python interpreter was started with the "-O" option.
* Some types that Cython provides internally, such as functions and
generators, are now shared across modules if more than one Cython
implemented module is imported.
* The type inference algorithm works more fine granular by taking the
results of the control flow analysis into account.
* A new script in bin/cythonize provides a command line frontend
to the cythonize() compilation function (including distutils build).
