This is better than generating invalid code; see #1695.

pyximport: remove obsolete version check

The file is syntactically correct only in Python >= 2.6, so the
version check would never be run.

This fixes #1702.

Support pickling of cdef classes.

Fix profiling for generators and generator expressions

This fixes #1700.

Now uses specialised functions for complex abs

Print no message if force=True

Closes #1664

add a compile test for github issue #1692: raising StopAsyncIteration without using "await" was missing utility code and failed to compile

Closes #1692

Repair incorrect C-API signature usage for PyUnicode_DecodeUTF16() when optimising bytes decoding from UTF-16(LE/BE)

Closes #1696

Remove obsolete documentation

Fix bad indentation in a pyximport test

    $ python pyximport/test/test_reload.py
      File "pyximport/test/test_reload.py", line 23
        assert hello.x == 1
        ^
    IndentationError: unexpected indent

on this regexp.
