I was reading this code and it wasn't obvious to me why we weren't
exec-ing directly into locals. So I got to learn something new :-)

gh-97799: use inspect.get_annotations in dataclass ( #97800 )
...
dataclass used to get the annotations on a class object using
cls.__dict__.get('__annotations__'). Now that it always imports
inspect, it can use inspect.get_annotations, which is modern
best practice for coping with annotations.

bpo-44674: Use unhashability as a proxy for mutability for default dataclass __init__ arguments. (GH-29867)
...
`@dataclass` in 3.10 prohibits using list, dict, or set as default values. It does this to avoid the mutable default problem. This test is both too strict, and not strict enough. Too strict, because some immutable subclasses should be safe, and not strict enough, because other mutable types should be prohibited. With this change applied, `@dataclass` now uses unhashability as a proxy for mutability: if objects aren't hashable, they're assumed to be mutable.

bpo-44649: Fix dataclasses(slots=True) with a field with a default, but init=False (GH-29692)
...
Special handling is needed, because for non-slots dataclasses the instance attributes are not set: reading from a field just references the class's attribute of the same name, which contains the default value. But this doesn't work for classes using __slots__: they don't read the class's attribute. So in that case (and that case only), initialize the instance attribute. Handle this for both normal defaults, and for fields using default_factory.

bpo-38605: Make 'from __future__ import annotations' the default (GH-20434)
...
The hard part was making all the tests pass; there are some subtle issues here, because apparently the future import wasn't tested very thoroughly in previous Python versions.
For example, `inspect.signature()` returned type objects normally (except for forward references), but strings with the future import. We changed it to try and return type objects by calling `typing.get_type_hints()`, but fall back on returning strings if that function fails (which it may do if there are future references in the annotations that require passing in a specific namespace to resolve).
