<blockquote>
<h2>22.1.0 (2022-04-03)</h2>
<ul>
<li>cattrs now uses the CalVer versioning convention.</li>
<li>cattrs now has a detailed validation mode, which is enabled by default. Learn more <code>here &lt;https://cattrs.readthedocs.io/en/latest/validation.html&gt;</code>_.
The old behavior can be restored by creating the converter with <code>detailed_validation=False</code>.</li>
<li><code>attrs</code> and dataclass structuring is now ~25% faster.</li>
<li>Fix an issue structuring bare <code>typing.List</code> s on Pythons lower than 3.9.
(<code>[#209](python-attrs/cattrs#209) &lt;https://github.com/python-attrs/cattrs/issues/209&gt;</code>_)</li>
<li>Fix structuring of non-parametrized containers like <code>list/dict/...</code> on Pythons lower than 3.9.
(<code>[#218](python-attrs/cattrs#218) &lt;https://github.com/python-attrs/cattrs/issues/218&gt;</code>_)</li>
<li>Fix structuring bare <code>typing.Tuple</code> on Pythons lower than 3.9.
(<code>[#218](python-attrs/cattrs#218) &lt;https://github.com/python-attrs/cattrs/issues/218&gt;</code>_)</li>
<li>Fix a wrong <code>AttributeError</code> of an missing <code>__parameters__</code> attribute. This could happen
when inheriting certain generic classes – for example <code>typing.*</code> classes are affected.
(<code>[#217](python-attrs/cattrs#217) &lt;https://github.com/python-attrs/cattrs/issues/217&gt;</code>_)</li>
<li>Fix structuring of <code>enum.Enum</code> instances in <code>typing.Literal</code> types.
(<code>[#231](python-attrs/cattrs#231) &lt;https://github.com/python-attrs/cattrs/pull/231&gt;</code>_)</li>
<li>Fix unstructuring all tuples - unannotated, variable-length, homogenous and heterogenous - to <code>list</code>.
(<code>[#226](python-attrs/cattrs#226) &lt;https://github.com/python-attrs/cattrs/issues/226&gt;</code>_)</li>
<li>For <code>forbid_extra_keys</code> raise custom <code>ForbiddenExtraKeyError</code> instead of generic <code>Exception</code>.
(<code>[#225](python-attrs/cattrs#225) &lt;https://github.com/python-attrs/cattrs/pull/225&gt;</code>_)</li>
<li>All preconf converters now support <code>loads</code> and <code>dumps</code> directly. See an example <code>here &lt;https://cattrs.readthedocs.io/en/latest/preconf.html&gt;</code>_.</li>
<li>Fix mappings with byte keys for the orjson, bson and tomlkit converters.
(<code>[#241](python-attrs/cattrs#241) &lt;https://github.com/python-attrs/cattrs/issues/241&gt;</code>_)</li>
</ul>
<h2>1.10.0 (2022-01-04)</h2>
<ul>
<li>Add PEP 563 (string annotations) support for dataclasses.
(<code>[#195](python-attrs/cattrs#195) &lt;https://github.com/python-attrs/cattrs/issues/195&gt;</code>_)</li>
<li>Fix handling of dictionaries with string Enum keys for bson, orjson, and tomlkit.</li>
<li>Rename the <code>cattr.gen.make_dict_unstructure_fn.omit_if_default</code> parameter to <code>_cattrs_omit_if_default</code>, for consistency. The <code>omit_if_default</code> parameters to <code>GenConverter</code> and <code>override</code> are unchanged.</li>
<li>Following the changes in <code>attrs</code> 21.3.0, add a <code>cattrs</code> package mirroring the existing <code>cattr</code> package. Both package names may be used as desired, and the <code>cattr</code> package isn't going away.</li>
</ul>
<h2>1.9.0 (2021-12-06)</h2>
<ul>
<li>Python 3.10 support, including support for the new union syntax (<code>A | B</code> vs <code>Union[A, B]</code>).</li>
<li>The <code>GenConverter</code> can now properly structure generic classes with generic collection fields.
(<code>[#149](python-attrs/cattrs#149) &lt;https://github.com/python-attrs/cattrs/issues/149&gt;</code>_)</li>
<li><code>omit=True</code> now also affects generated structuring functions.
(<code>[#166](python-attrs/cattrs#166) &lt;https://github.com/python-attrs/cattrs/issues/166&gt;</code>_)</li>
<li><code>cattr.gen.{make_dict_structure_fn, make_dict_unstructure_fn}</code> now resolve type annotations automatically when PEP 563 is used.
(<code>[#169](python-attrs/cattrs#169) &lt;https://github.com/python-attrs/cattrs/issues/169&gt;</code>_)</li>
<li>Protocols are now unstructured as their runtime types.
(<code>[#177](python-attrs/cattrs#177) &lt;https://github.com/python-attrs/cattrs/pull/177&gt;</code>_)</li>
<li>Fix an issue generating structuring functions with renaming and <code>_cattrs_forbid_extra_keys=True</code>.
(<code>[#190](python-attrs/cattrs#190) &lt;https://github.com/python-attrs/cattrs/issues/190&gt;</code>_)</li>
</ul>
<h2>1.8.0 (2021-08-13)</h2>
<ul>
<li>Fix <code>GenConverter</code> mapping structuring for unannotated dicts on Python 3.8.</li>
</ul>
