0.27.3

===================

Bugs fixed

• String forward references to extension types like cython.locals(x="ExtType")
  failed to find the named type. (Github issue 1962)

• NumPy slicing generated incorrect results when compiled with Pythran.
  Original patch by Serge Guelton (Github issue 1946).

  Patch by Jeroen Demeyer (Github issue 1975).

0.27.2

===================

Bugs fixed

• Comprehensions could incorrectly be optimised away when they appeared in boolean
  test contexts. (Github issue 1920)

• The special methods __eq__, __lt__ etc. in extension types did not type
  their first argument as the type of the class but object. (Github issue 1935)

• Crash on first lookup of "cline_in_traceback" option during exception handling.
  (Github issue 1907)

• Some nested module level comprehensions failed to compile.
  (Github issue 1906)

• Compiler crash on some complex type declarations in pure mode.
  (Github issue 1908)

• std::unordered_map.erase() was declared with an incorrect void return
  type in libcpp.unordered_map. (Github issue 1484)

• Invalid use of C++ fallthrough attribute before C++11 and similar issue in clang.
  (Github issue 1930)

• Compiler crash on misnamed properties. (Github issue 1905)

0.27.1

===================

Features added

• The Jupyter magic has a new debug option --verbose that shows details about
  the distutils invocation. Patch by Boris Filippov (Github issue 1881).

Bugs fixed

• Py3 list comprehensions in class bodies resulted in invalid C code.
  (Github issue 1889)

• Modules built for later CPython 3.5.x versions failed to import in 3.5.0/3.5.1.
  (Github issue 1880)

• Deallocating fused types functions and methods kept their GC tracking enabled,
  which could potentially lead to recursive deallocation attempts.

• Crash when compiling in C++ mode with old setuptools versions.
  (Github issue 1879)

• C++ object arguments for the constructor of Cython implemented C++ are now
  passed by reference and not by value to allow for non-copyable arguments, such
  as unique_ptr.

• API-exported C++ classes with Python object members failed to compile.
  (Github issue 1866)

• Some issues with the new relaxed exception value handling were resolved.

• Python classes as annotation types could prevent compilation.
  (Github issue 1887)

• Cython annotation types in Python files could lead to import failures
  with a "cython undefined" error. Recognised types are now turned into strings.

• Coverage analysis could fail to report on extension modules on some platforms.

• Annotations could be parsed (and rejected) as types even with
  annotation_typing=False.

Other changes

• PEP 489 support has been disabled by default to counter incompatibilities with
  import setups that try to reload or reinitialise modules.

0.27

=================

Features added

• Extension module initialisation follows
  PEP 489 <https://www.python.org/dev/peps/pep-0489/>_ in CPython 3.5+, which
  resolves several differences with regard to normal Python modules. This makes
  the global names __file__ and __path__ correctly available to module
  level code and improves the support for module-level relative imports.
  (Github issues 1715, 1753, 1035)

• Asynchronous generators (PEP 525 <https://www.python.org/dev/peps/pep-0525/>)
  and asynchronous comprehensions (PEP 530 <https://www.python.org/dev/peps/pep-0530/>)
  have been implemented. Note that async generators require finalisation support
  in order to allow for asynchronous operations during cleanup, which is only
  available in CPython 3.6+. All other functionality has been backported as usual.

• Variable annotations are now parsed according to
  PEP 526 <https://www.python.org/dev/peps/pep-0526/>_. Cython types (e.g.
  cython.int) are evaluated as C type declarations and everything else as Python
  types. This can be disabled with the directive annotation_typing=False.
  Note that most complex PEP-484 style annotations are currently ignored. This will
  change in future releases. (Github issue 1850)

• Extension types (also in pure Python mode) can implement the normal special methods
  __eq__, __lt__ etc. for comparisons instead of the low-level __richcmp__
  method. (Github issue 690)

• New decorator cython.exceptval(x=None, check=False) that makes the signature
  declarations except x, except? x and except * available to pure Python
  code. Original patch by Antonio Cuni. (Github issue 1653)

• Signature annotations are now included in the signature docstring generated by
  the embedsignature directive. Patch by Lisandro Dalcin (Github issue 1781).

• The gdb support for Python code (libpython.py) was updated to the latest
  version in CPython 3.7 (git rev 5fe59f8).

• The compiler tries to find a usable exception return value for cdef functions
  with except * if the returned type allows it. Note that this feature is subject
  to safety limitations, so it is still better to provide an explicit declaration.

• C functions can be assigned to function pointers with a compatible exception
  declaration, not only with exact matches. A side-effect is that certain compatible
  signature overrides are now allowed and some more mismatches of exception signatures
  are now detected and rejected as errors that were not detected before.

• The IPython/Jupyter magic integration has a new option %%cython --pgo for profile
  guided optimisation. It compiles the cell with PGO settings for the C compiler,
  executes it to generate a runtime profile, and then compiles it again using that
  profile for C compiler optimisation. Currently only tested with gcc.

• len(memoryview) can be used in nogil sections to get the size of the
  first dimension of a memory view (shape[0]). (Github issue 1733)

• C++ classes can now contain (properly refcounted) Python objects.

• NumPy dtype subarrays are now accessible through the C-API.
  Patch by Gerald Dalley (Github issue 245).

• Resolves several issues with PyPy and uses faster async slots in PyPy3.
  Patch by Ronan Lamy (Github issues 1871, 1878).

Bugs fixed

• Extension types that were cimported from other Cython modules could disagree
  about the order of fused cdef methods in their call table. This could lead
  to wrong methods being called and potentially also crashes. The fix required
  changes to the ordering of fused methods in the call table, which may break
  existing compiled modules that call fused cdef methods across module boundaries,
  if these methods were implemented in a different order than they were declared
  in the corresponding .pxd file. (Github issue 1873)

• The exception state handling in generators and coroutines could lead to
  exceptions in the caller being lost if an exception was raised and handled
  inside of the coroutine when yielding. (Github issue 1731)

• Loops over range(enum) were not converted into C for-loops. Note that it
  is still recommended to use an explicit cast to a C integer type in this case.

• Error positions of names (e.g. variables) were incorrectly reported after the
  name and not at the beginning of the name.

• Compile time DEF assignments were evaluated even when they occur inside of
  falsy IF blocks. (Github issue 1796)

• Disabling the line tracing from a trace function could fail.
  Original patch by Dmitry Trofimov. (Github issue 1769)

• Several issues with the Pythran integration were resolved.

• abs(signed int) now returns a signed rather than unsigned int.
  (Github issue 1837)

• Reading frame.f_locals of a Cython function (e.g. from a debugger or profiler
  could modify the module globals. (Github issue 1836)

• Buffer type mismatches in the NumPy buffer support could leak a reference to the
  buffer owner.

• Using the "is_f_contig" and "is_c_contig" memoryview methods together could leave
  one of them undeclared. (Github issue 1872)

• Compilation failed if the for-in-range loop target was not a variable but a more
  complex expression, e.g. an item assignment. (Github issue 1831)

• Compile time evaluations of (partially) constant f-strings could show incorrect
  results.

• Escape sequences in raw f-strings (fr'...') were resolved instead of passing
  them through as expected.

• Some ref-counting issues in buffer error handling have been resolved.

Other changes

• Type declarations in signature annotations are now parsed according to
  PEP 484 <https://www.python.org/dev/peps/pep-0484/>_
  typing. Only Cython types (e.g. cython.int) and Python builtin types are
  currently considered as type declarations. Everything else is ignored, but this
  will change in a future Cython release.
  (Github issue 1672)

• The directive annotation_typing is now True by default, which enables
  parsing type declarations from annotations.

• This release no longer supports Python 3.2.

0.26.1

===================

Features added

Bugs fixed

• cython.view.array was missing .__len__().

• Extension types with a .pxd override for their __releasebuffer__ slot
  (e.g. as provided by Cython for the Python array.array type) could leak
  a reference to the buffer owner on release, thus not freeing the memory.
  (Github issue 1638)

• Auto-decoding failed in 0.26 for strings inside of C++ containers.
  (Github issue 1790)

• Compile error when inheriting from C++ container types.
  (Github issue 1788)

• Invalid C code in generators (declaration after code).
  (Github issue 1801)

• Arithmetic operations on const integer variables could generate invalid code.
  (Github issue 1798)

• Local variables with names of special Python methods failed to compile inside of
  closures. (Github issue 1797)

• Problem with indirect Emacs buffers in cython-mode.
  Patch by Martin Albrecht (Github issue 1743).

• Extension types named result or PickleError generated invalid unpickling code.
  Patch by Jason Madden (Github issue 1786).

• Bazel integration failed to compile .py files.
  Patch by Guro Bokum (Github issue 1784).

• Some include directories and dependencies were referenced with their absolute paths
  in the generated files despite lying within the project directory.

• Failure to compile in Py3.7 due to a modified signature of _PyCFunctionFast()

0.26

=================

Features added

• Pythran can be used as a backend for evaluating NumPy array expressions.
  Patch by Adrien Guinet (Github issue 1607).

• cdef classes now support pickling by default when possible.
  This can be disabled with the auto_pickle directive.

• Speed up comparisons of strings if their hash value is available.
  Patch by Claudio Freire (Github issue 1571).

• Support pyximport from zip files.
  Patch by Sergei Lebedev (Github issue 1485).

• IPython magic now respects the __all__ variable and ignores
  names with leading-underscore (like import * does).
  Patch by Syrtis Major (Github issue 1625).

• abs() is optimised for C complex numbers.
  Patch by da-woods (Github issue 1648).

• The display of C lines in Cython tracebacks can now be enabled at runtime
  via import cython_runtime; cython_runtime.cline_in_traceback=True.
  The default has been changed to False.

• The overhead of calling fused types generic functions was reduced.

• "cdef extern" include files are now also searched relative to the current file.
  Patch by Jeroen Demeyer (Github issue 1654).

• Optional optimization for re-aquiring the GIL, controlled by the
  fast_gil directive.

Bugs fixed

• Item lookup/assignment with a unicode character as index that is typed
  (explicitly or implicitly) as Py_UCS4 or Py_UNICODE used the
  integer value instead of the Unicode string value. Code that relied on
  the previous behaviour now triggers a warning that can be disabled by
  applying an explicit cast. (Github issue 1602)

• f-string processing was adapted to changes in PEP 498 and CPython 3.6.

• Invalid C code when decoding from UTF-16(LE/BE) byte strings.
  (Github issue 1696)

• Unicode escapes in 'ur' raw-unicode strings were not resolved in Py2 code.
  Original patch by Aaron Gallagher (Github issue 1594).

• File paths of code objects are now relative.
  Original patch by Jelmer Vernooij (Github issue 1565).

• Decorators of cdef class methods could be executed twice.
  Patch by Jeroen Demeyer (Github issue 1724).

• Dict iteration using the Py2 iter* methods failed in PyPy3.
  Patch by Armin Rigo (Github issue 1631).

• Several warnings in the generated code are now suppressed.

Other changes

• The unraisable_tracebacks option now defaults to True.

• Coercion of C++ containers to Python is no longer automatic on attribute
  access (Github issue 1521).

• Access to Python attributes of cimported modules without the corresponding
  import is now a compile-time (rather than runtime) error.

• Do not use special dll linkage for "cdef public" functions.
  Patch by Jeroen Demeyer (Github issue 1687).

• cdef/cpdef methods must match their declarations. See Github Issue 1732.
  This is now a warning and will be an error in future releases.

not just the ones defined in (or generated from) envlist.

New verbosity settings for -l and -a: show user defined descriptions

Note that for backwards compatibility with scripts using the output of -l
it's output remains unchanged.
