* AtomMeta: create the class only once all members have been
customized
This allows to use ``__init_subclass__`` since previously the
``__atom_members__`` was not set when ``__init_subclass__``
was called
* illustrate the use of ``__init_subclass__`` to customize
pickling
* refactor the metaclass to make it easier to reason about
* add a ``DefaultDict`` member which enforce the value to be a
dictionary and use a factory for missing keys. The factory
is set at the member level and a normal dict can be provided
as value. When possible the factory is deduced from the member
used for validation.
* infer the use of ``DefaultDict`` from a
``collections.defaultdict`` annotation

* fix the generation of Subclass from type annotations PR #193
* move getstate and setstate implementation to C and allow to
customize the condition under which a member value is
pickled. PR #182
* Customization is used to only pickle member value whose
state can be restored (for example Constant is not
pickled). Whether a member is pickled can be customized
using a method prefixed with ``_getstate_`` on an Atom
subclass.
* use the Typed member when a type annotation resolve to a
single type whose metaclass does not implement a custom
``__instancecheck__`` PR #185
* generate Tuple member for tuple[] annotations.
The content of the tuple is typed check only if it is a
1-tuple or variable-length tuple. PR #184
* fix the resolution order of members in the presence of
multiple inheritance with a common base class PR
* Due to the above changes, adding a member after the class
definition requires more work than before. As a
consequence a new helper function ``add_member`` has
been added.

on type annotations.

PR #141
* base the version number on the most recent git tag using
setuptools-scm PR #141
* make the setup compatible with PEP 517 and PEP 621 compliant PR
#141#162 Pip should be used for development install in place
of directly calling setup.py
+ fix handling of _SpecialGenericAlias (typing.Sequence, ...)
when used inside an Instance member PR #151
* add a ChangeDict TypedDict to help annotate observers PR #133
* add several keyword argument to the AtomMeta metaclass PR #133
- enable_weakrefs: allow to have weak references to an Atom
object without having to add the slot by hand. False by
default.
- use_annotations: generate members from type annotations.
Str-like annotations are not supported but allowed when an
actual member is provided as default value. True by default.
- type_containers: in conjunction with use_annotations
determine to what depth to type the content of a container.
The default is 1 meaning that list[int] will use List(Int())
but list[list[int]] will use List(List()).
* allow specifying which change events are emitted when adding
static observers PR #155

- Update to 0.7.0:
* allow to use any subscribed type in Typed and Instance. Optional and Union are
analyzed to extract the tuple of types to validate. The presence of NoneType in
the tuple will make the member optional. For container types (list, dict, set, etc)
the content types is not used beyond static type validation. PR #136#140
Note however that this usage of Optional and Union breaks static analyzer currently,
while things deriving from an actual type will work as expected (List[int], list[int],
Iterable[int])
* make the factory argument of Typed, Instance and their forwarded version
keyword only. PR #123
* add a keyword-only argument to Typed, Instance and their forwarded
version: ``optional``. When set to False, this will cause those members to
reject None as a valid value. The default value, None, will resolve to True
if there is no provided way to build a default value. PR #123 # 131
This is backward incompatible since previously None was always a valid value.
* the Instance and Typed variants of the Validate enum have been renamed to
OptionalInstance, OptionalTyped and new Instance and Typed variant describing
the validation behavior for the member with optional=False have been added. PR #123
* consistently use Instance to wrap types passed to containers. PR #123
For containers, Instance members used for validation are created with
optional=False by default. This is backward incompatible since None was always
a valid value previously.
* add strict argument to FloatRange. PR #124
* allow to specify the type of ReadOnly and Constant. PR #128
The validation is done using the Instance validator. The change for ReadOnly
is backward incompatible since the type or tuple of type is the first argument
in place of the default value. Specifying the default value by keyword is both
forward and backward compatible.
* use python stdlib IntEnum instead of the custom one in atom PR #122
* remove the custom atom.IntEnum PR #122
