 ## Next Release
 
+## Mypy 1.16
+
+We’ve just uploaded mypy 1.16 to the Python Package Index ([PyPI](https://pypi.org/project/mypy/)).
+Mypy is a static type checker for Python. This release includes new features and bug fixes.
+You can install it as follows:
+
+    python3 -m pip install -U mypy
+
+You can read the full documentation for this release on [Read the Docs](http://mypy.readthedocs.io).
+
 ### Different Property Getter and Setter Types
 
-Mypy now supports using different types for property getter and setter.
+Mypy now supports using different types for a property getter and setter:
+
 ```python
 class A:
-    value: int
+    _value: int
 
     @property
-    def f(self) -> int:
-        return self.value
-    @f.setter
-    def f(self, x: str | int) -> None:
+    def foo(self) -> int:
+        return self._value
+
+    @foo.setter
+    def foo(self, x: str | int) -> None:
         try:
-            self.value = int(x)
+            self._value = int(x)
         except ValueError:
-            raise Exception(f"'{x}' is not a valid value for 'f'")
+            raise Exception(f"'{x}' is not a valid value for 'foo'")
 ```
+This was contributed by Ivan Levkivskyi (PR [18510](https://github.com/python/mypy/pull/18510)).
+
+### Flexible Variable Redefinitions (Experimental)
+
+Mypy now allows unannotated variables to be freely redefined with
+different types when using the experimental `--allow-redefinition-new`
+flag. You will also need to enable `--local-partial-types`. Mypy will
+now infer a union type when different types are assigned to a
+variable:
 
-Contributed by Ivan Levkivskyi (PR [18510](https://github.com/python/mypy/pull/18510))
+```py
+# mypy: allow-redefinition-new, local-partial-types
+
+def f(n: int, b: bool) -> int | str:
+    if b:
+        x = n
+    else:
+        x = str(n)
+    # Type of 'x' is int | str here.
+    return x
+```
+
+Without the new flag, mypy only supports inferring optional types (`X
+| None`) from multiple assignments, but now mypy can infer arbitrary
+union types.
+
+An unannotated variable can now also have different types in different
+code locations:
+
+```py
+# mypy: allow-redefinition-new, local-partial-types
+...
+
+if cond():
+    for x in range(n):
+        # Type of 'x' is 'int' here
+        ...
+else:
+    for x in ['a', 'b']:
+        # Type of 'x' is 'str' here
+        ...
+```
+
+We are planning to turn this flag on by default in mypy 2.0, along
+with `--local-partial-types`. The feature is still experimental and
+has known issues, and the semantics may still change in the
+future. You may need to update or add type annotations when switching
+to the new behavior, but if you encounter anything unexpected, please
+create a GitHub issue.
+
+This was contributed by Jukka Lehtosalo
+(PR [18727](https://github.com/python/mypy/pull/18727), PR [19153](https://github.com/python/mypy/pull/19153)).
+
+### Stricter Type Checking with Imprecise Types
+
+Mypy can now detect additional errors in code that uses `Any` types or has missing function annotations.
+
+When calling `dict.get(x, None)` on an object of type `dict[str, Any]`, this
+now results in an optional type (in the past it was `Any`):
+
+```python
+def f(d: dict[str, Any]) -> int:
+    # Error: Return value has type "Any | None" but expected "int"
+    return d.get("x", None)
+```
+
+Type narrowing using assignments can result in more precise types in
+the presence of `Any` types:
+
+```python
+def foo(): ...
+
+def bar(n: int) -> None:
+    x = foo()
+    # Type of 'x' is 'Any' here
+    if n > 5:
+        x = str(n)
+        # Type of 'x' is 'str' here
+```
+
+When using `--check-untyped-defs`, unannotated overrides are now
+checked more strictly against superclass definitions.
+

+ * Use union types instead of join in binder (Ivan Levkivskyi, PR [18538](https://github.com/python/mypy/pull/18538))
+ * Check superclass compatibility of untyped methods if `--check-untyped-defs` is set (Stanislav Terliakov, PR [18970](https://github.com/python/mypy/pull/18970))
+
+### Improvements to Attribute Resolution
+
+This release includes several fixes to inconsistent resolution of attribute, method and descriptor types.
+
+ * Consolidate descriptor handling (Ivan Levkivskyi, PR [18831](https://github.com/python/mypy/pull/18831))
+ * Make multiple inheritance checking use common semantics (Ivan Levkivskyi, PR [18876](https://github.com/python/mypy/pull/18876))
+ * Make method override checking use common semantics  (Ivan Levkivskyi, PR [18870](https://github.com/python/mypy/pull/18870))

+ * Make descriptor handling behave consistently (Ivan Levkivskyi, PR [18831](https://github.com/python/mypy/pull/18831))
+
+### Make Implementation for Abstract Overloads Optional
+
+The implementation can now be omitted for abstract overloaded methods,
+even outside stubs:
+
+```py
+from abc import abstractmethod
+from typing import overload
+
+class C:
+    @abstractmethod
+    @overload
+    def foo(self, x: int) -> int: ...
+
+    @abstractmethod
+    @overload
+    def foo(self, x: str) -> str: ...
+
+    # No implementation required for "foo"
+```
+
+This was contributed by Ivan Levkivskyi (PR [18882](https://github.com/python/mypy/pull/18882)).
+
+### Option to Exclude Everything in .gitignore
+
+You can now use `--exclude-gitignore` to exclude everything in a
+`.gitignore` file from the mypy build. This behaves similar to
+excluding the paths using `--exclude`. We might enable this by default
+in a future mypy release.
+
+This was contributed by Ivan Levkivskyi (PR [18696](https://github.com/python/mypy/pull/18696)).

 It's now possible to selectively disable warnings generated from
 [`warnings.deprecated`](https://docs.python.org/3/library/warnings.html#warnings.deprecated)

+### Annotating Native/Non-Native Classes in Mypyc
+
+You can now declare a class as a non-native class when compiling with
+mypyc. Unlike native classes, which are extension classes and have an
+immutable structure, non-native classes are normal Python classes at
+runtime and are fully dynamic.  Example:
+
+```python
+from mypy_extensions import mypyc_attr
+
+@mypyc_attr(native_class=False)
+class NonNativeClass:
+    ...
+
+o = NonNativeClass()
+
+# Ok, even if attribute "foo" not declared in class body
+setattr(o, "foo", 1)
+```
+
+Classes are native by default in compiled modules, but classes that
+use certain features (such as most metaclasses) are implicitly
+non-native.
+
+You can also explicitly declare a class as native. In this case mypyc
+will generate an error if it can't compile the class as a native
+class, instead of falling back to a non-native class:
+
+```python
+from mypy_extensions import mypyc_attr
+from foo import MyMeta
+
+# Error: Unsupported metaclass for a native class
+@mypyc_attr(native_class=True)
+class C(metaclass=MyMeta):
+    ...
+```
+
+Since native classes are significantly more efficient that non-native
+classes, you may want to ensure that certain classes always compiled
+as native classes.
+
+This feature was contributed by Valentin Stanciu (PR [18802](https://github.com/python/mypy/pull/18802)).

     This flag causes mypy to suppress errors caused by not being able to fully
     infer the types of global and class variables.
 
-.. option:: --allow-redefinition
+.. option:: --allow-redefinition-new
 
     By default, mypy won't allow a variable to be redefined with an
-    unrelated type. This flag enables redefinition of a variable with an
+    unrelated type. This *experimental* flag enables the redefinition of
+    unannotated variables with an arbitrary type. You will also need to enable
+    :option:`--local-partial-types <mypy --local-partial-types>`.
+    Example:
+
+    .. code-block:: python
+
+        def maybe_convert(n: int, b: bool) -> int | str:
+            if b:
+                x = str(n)  # Assign "str"
+            else:
+                x = n       # Assign "int"
+            # Type of "x" is "int | str" here.
+            return x
+
+    Without the new flag, mypy only supports inferring optional types
+    (``X | None``) from multiple assignments. With this option enabled,
+    mypy can infer arbitrary union types.
+
+    This also enables an unannotated variable to have different types in different
+    code locations:
+
+    .. code-block:: python
+
+        if check():
+            for x in range(n):
+                # Type of "x" is "int" here.
+                ...
+        else:
+            for x in ['a', 'b']:
+                # Type of "x" is "str" here.
+                ...
+
+    Note: We are planning to turn this flag on by default in a future mypy
+    release, along with :option:`--local-partial-types <mypy --local-partial-types>`.
+    The feature is still experimental, and the semantics may still change.
+
+.. option:: --allow-redefinition
+
+    This is an older variant of
+    :option:`--allow-redefinition-new <mypy --allow-redefinition-new>`.
+    This flag enables redefinition of a variable with an
     arbitrary type *in some contexts*: only redefinitions within the
     same block and nesting depth as the original definition are allowed.
+
+    We have no plans to remove this flag, but we expect that
+    :option:`--allow-redefinition-new <mypy --allow-redefinition-new>`
+    will replace this flag for new use cases eventually.

+
+Defining non-native classes
+---------------------------
+
+You can use the ``@mypy_extensions.mypyc_attr(...)`` class decorator
+with an argument ``native_class=False`` to explicitly define normal
+Python classes (non-native classes)::
+
+    from mypy_extensions import mypyc_attr
+
+    @mypyc_attr(native_class=False)
+    class NonNative:
+        def __init__(self) -> None:
+            self.attr = 1
+
+    setattr(NonNative, "extra", 1)  # Ok
+
+This only has an effect in classes compiled using mypyc. Non-native
+classes are significantly less efficient than native classes, but they
+are sometimes necessary to work around the limitations of native classes.
+
+Non-native classes can use arbitrary metaclasses and class decorators,
+and they support flexible multiple inheritance.  Mypyc will still
+generate a compile-time error if you try to assign to a method, or an
+attribute that is not defined in a class body, since these are static
+type errors detected by mypy::
+
+    o = NonNative()
+    o.extra = "x"  # Static type error: "extra" not defined
+
+However, these operations still work at runtime, including in modules
+that are not compiled using mypyc. You can also use ``setattr`` and
+``getattr`` for dynamic access of arbitrary attributes. Expressions
+with an ``Any`` type are also not type checked statically, allowing
+access to arbitrary attributes::
+
+    a: Any = o
+    a.extra = "x"  # Ok
+
+    setattr(o, "extra", "y")  # Also ok
+
+Implicit non-native classes
+---------------------------
+
+If a compiled class uses an unsupported metaclass or an unsupported
+class decorator, it will implicitly be a non-native class, as
+discussed above. You can still use ``@mypyc_attr(native_class=False)``
+to explicitly mark it as a non-native class.
+
+Explicit native classes
+-----------------------
+
+You can use ``@mypyc_attr(native_class=True)`` to explicitly declare a
+class as a native class. It will be a compile-time error if mypyc
+can't compile the class as a native class. You can use this to avoid
+accidentally defining implicit non-native classes.
