Mypy Release Notes

Next Release

Mypy 2.2

We've just uploaded mypy 2.2.0 to the Python Package Index (PyPI). Mypy is a static type checker for Python. This release includes new features, performance improvements 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.

Support for Closed TypedDicts (PEP 728)

Mypy now supports closed TypedDicts as specified in PEP 728. A closed TypedDict cannot have extra keys beyond those explicitly defined. This allows the type checker to determine that certain operations are safe when they otherwise wouldn't be due to the potential presence of unknown keys.

You can use the closed keyword argument with TypedDict:

HasName = TypedDict("HasName", {"name": str})
HasOnlyName = TypedDict("HasOnlyName", {"name": str}, closed=True)
Movie = TypedDict("Movie", {"name": str, "year": int})
movie: Movie = {"name": "Nimona", "year": 2023}
has_name: HasName = movie  # OK: HasName is open (default)
has_only_name: HasOnlyName = movie  # Error: HasOnlyName is closed and Movie has extra "year" key

Closed TypedDicts enable more precise type checking because the type checker knows exactly which keys are present. This is particularly useful when working with TypedDict unions or when you want to ensure that a TypedDict conforms to an exact shape.

The closed keyword also enables safe type narrowing with in checks:

Book = TypedDict('Book', {'book': str}, closed=True)
DVD = TypedDict('DVD', {'dvd': str}, closed=True)
type Inventory = Book | DVD
def print_type(inventory: Inventory) -> None:
if "book" in inventory:
# Type is narrowed to Book here - safe because DVD is closed
print(inventory["book"])
else:
# Type is narrowed to DVD here
print(inventory["dvd"])
</tr></table>

Full Changelog: tox-dev/tox@4.56.1...4.56.2

Changelog

Sourced from tox's changelog.

Bug fixes - 4.56.4

• Discover debug (Py_DEBUG) interpreters set as base_python, such as Debian's python3.13-dbg - the spec was misread as a machine named dbg and no interpreter matched. Requires python-discovery>=1.4.4 - by :user:gaborbernat. (:issue:3977)

---

v4.56.3 (2026-07-08)

---

Bug fixes - 4.56.3

• Stop double-closing the child pty file descriptor when running under a tty, which could race a parallel run that had reused the freed descriptor number and cause intermittent Bad file descriptor/Input/output error failures - by :user:apoorvdarshan. (:issue:3975)

---

v4.56.2 (2026-07-07)

---

Bug fixes - 4.56.2

• Fix a batch of latent defects found in a codebase audit:

  • stop duplicating --extra-index-url when a merged requirements line repeats an already-seen index;
  • render --no-binary/--only-binary as comma-joined strings instead of leaking the internal set into the pip command line;
  • report a clear error instead of IndexError for a bare one-argument flag (-c, -r, -f, -e) in deps or constraints;
  • canonicalize optional-dependencies keys and self-referential (recursive) extra names so non-canonical spellings no longer silently drop dependencies;
  • raise a clear error instead of KeyError when dependency_groups is requested without a [dependency-groups] table;
  • stop a native TOML { replace = "env" } reference from leaking its resolution chain into sibling list entries and tripping a spurious circular chain error;
  • expand the range that actually matched in a factor expression rather than the first identical digit-range substring;
  • strip the backslash from an escaped \; in set_env values;
  • skip option values during command auto-detection so an environment named like a subcommand (e.g. tox -e list) is no longer misread;
  • treat an empty list-typed environment variable (e.g. TOX_DISCOVER=) as an empty list rather than [""];
  • report an environment whose name is an empty string as present in Config membership tests;
  • fail evaluation gracefully instead of crashing the driver thread when tox p -p all is run with an empty selection;
  • avoid rebuilding a throwaway PEP 517 frontend against the previous root when a package environment's root is reassigned before a frontend exists;
  • avoid crashing create_session_view when the package and its session copy share no common path (e.g. different Windows drives);
