- Version update to 0.28.1:
  * PyFrozenSet_New() was accidentally used in PyPy where it is lacking
    from the C-API.
  * Assignment between some C++ templated types were incorrectly rejected
    when the templates mix const with ctypedef. (Github issue #2148)
  * Undeclared C++ no-args constructors in subclasses could make the
    compilation fail if the base class constructor was declared without
    nogil. (Github issue #2157)
  * Bytes %-formatting inferred basestring (bytes or unicode) as result type
    in some cases where bytes would have been safe to infer. (Github issue #2153)
  * None was accidentally disallowed as typed return value of dict.pop().

- update to version 0.28:
  * Features added
    + Cdef classes can now multiply inherit from ordinary Python
      classes. (The primary base must still be a c class, possibly
      object, and the other bases must not be cdef classes.)
    + Type inference is now supported for Pythran compiled NumPy
      expressions. Patch by Nils Braun. (Github issue #1954)
    + The const modifier can be applied to memoryview declarations to
      allow read-only buffers as input. (Github issues #1605, #1869)
    + C code in the docstring of a cdef extern block is copied
      verbatimly into the generated file. Patch by Jeroen
      Demeyer. (Github issue #1915)
    + When compiling with gcc, the module init function is now tuned
      for small code size instead of whatever compile flags were
      provided externally. Cython now also disables some code
      intensive optimisations in that function to further reduce the
      code size. (Github issue #2102)
    + Decorating an async coroutine with @cython.iterable_coroutine

- update to version 0.28:
* Features added
+ Cdef classes can now multiply inherit from ordinary Python
classes. (The primary base must still be a c class, possibly
object, and the other bases must not be cdef classes.)
+ Type inference is now supported for Pythran compiled NumPy
expressions. Patch by Nils Braun. (Github issue #1954)
+ The const modifier can be applied to memoryview declarations to
allow read-only buffers as input. (Github issues #1605, #1869)

+ When compiling with gcc, the module init function is now tuned
for small code size instead of whatever compile flags were
provided externally. Cython now also disables some code
intensive optimisations in that function to further reduce the
code size. (Github issue #2102)
+ Decorating an async coroutine with @cython.iterable_coroutine
changes its type at compile time to make it iterable. While this
is not strictly in line with PEP-492, it improves the
interoperability with old-style coroutines that use yield from
instead of await.
+ The IPython magic has preliminary support for
JupyterLab. (Github issue #1775)
+ The new TSS C-API in CPython 3.7 is supported and has been
backported. Patch by Naotoshi Seo. (Github issue #1932)
+ Cython knows the new Py_tss_t type defined in PEP-539 and
automatically initialises variables declared with that type to
Py_tss_NEEDS_INIT, a value which cannot be used outside of
static assignments.
+ The set methods .remove() and .discard() are optimised. Patch by
Antoine Pitrou. (Github issue #2042)
+ dict.pop() is optimised. Original patch by Antoine
Pitrou. (Github issue #2047)
+ Iteration over sets and frozensets is optimised. (Github issue
#2048)
+ Safe integer loops (< range(2^30)) are automatically optimised
into C loops.
+ alist.extend([a,b,c]) is optimised into sequential list.append()
calls for short literal sequences.
+ Calls to builtin methods that are not specifically optimised
into C-API calls now use a cache that avoids repeated lookups of
the underlying C function. (Github issue #2054)
+ Single argument function calls can avoid the argument tuple
creation in some cases.
+ Some redundant extension type checks are avoided.
+ Formatting C enum values in f-strings is faster, as well as some
other special cases.
+ String formatting with the '%' operator is optimised into
f-strings in simple cases.
+ Subscripting (item access) is faster in some cases.
+ Some bytearray operations have been optimised similar to bytes.
+ Some PEP-484/526 container type declarations are now considered
for loop optimisations.
+ Indexing into memoryview slices with view[i][j] is now optimised
into view[i, j].
+ Python compatible cython.* types can now be mixed with type
declarations in Cython syntax.
+ Name lookups in the module and in classes are faster.
+ Python attribute lookups on extension types without instance
dict are faster.
+ Some missing signals were added to libc/signal.pxd. Patch by
Jeroen Demeyer. (Github issue #1914)
+ The warning about repeated extern declarations is now visible by
default. (Github issue #1874)
+ The exception handling of the function types used by CPython's
type slot functions was corrected to match the de-facto standard
behaviour, so that code that uses them directly benefits from
automatic and correct exception propagation. Patch by Jeroen
Demeyer. (Github issue #1980)
+ Defining the macro CYTHON_NO_PYINIT_EXPORT will prevent the
module init function from being exported as symbol, e.g. when
linking modules statically in an embedding setup. Patch by
AraHaan. (Github issue #1944)
* Bugs fixed
+ If a module name is explicitly provided for an Extension() that
is compiled via cythonize(), it was previously ignored and
replaced by the source file name. It can now be used to override
the target module name, e.g. for compiling prefixed accelerator
modules from Python files. (Github issue #2038)
+ The arguments of the num_threads parameter of parallel sections
were not sufficiently validated and could lead to invalid C
code. (Github issue #1957)
+ Catching exceptions with a non-trivial exception pattern could
call into CPython with a live exception set. This triggered
incorrect behaviour and crashes, especially in CPython 3.7.
+ The signature of the special __richcmp__() method was corrected
to recognise the type of the first argument as self. It was
previously treated as plain object, but CPython actually
guarantees that it always has the correct type. Note: this can
change the semantics of user code that previously relied on self
being untyped.
+ Some Python 3 exceptions were not recognised as builtins when
running Cython under Python 2.
+ Some async helper functions were not defined in the generated C
code when compiling simple async code. (Github issue #2075)
+ Line tracing did not include generators and coroutines. (Github
issue #1949)
+ C++ declarations for unordered_map were corrected. Patch by
Michael Schatzow. (Github issue #1484)
+ Iterator declarations in C++ deque and vector were
corrected. Patch by Alex Huszagh. (Github issue #1870)
+ The const modifiers in the C++ string declarations were
corrected, together with the coercion behaviour of string
literals into C++ strings. (Github issue #2132)
+ Some declaration types in libc.limits were corrected. Patch by
Jeroen Demeyer. (Github issue #2016)
+ @cython.final was not accepted on Python classes with an
@cython.cclass decorator. (Github issue #2040)
+ Cython no longer creates useless and incorrect PyInstanceMethod
wrappers for methods in Python 3. Patch by Jeroen
Demeyer. (Github issue #2105)
+ The builtin bytearray type could not be used as base type of
cdef classes. (Github issue #2106)
