What’s new in PyPy2.7 7.0+¶
Make sure zlib decompressobjs have their streams deallocated immediately on flush.
Fix calling copy on already-flushed compressobjs.
Improve performance of long operations where one of the operands fits into an int.
Improve register allocation in the JIT.
Implement rlib.jit.promote_unicode to complement promote_string
Use utf8 internally to represent unicode, with the goal of never using rpython-level unicode
Since _ctypes is implemented in pure python over libffi, add interfaces and
methods to support the buffer interface from python. Specifically, add a
__pypy__.newmemoryview
function to create a memoryview and extend the use
of the PyPy-specific __buffer__
class method.
