  :issue:2205

  • OptionParser and the parser module, which is a modified copy of
    optparse in the standard library.
  • Context.protected_args is unneeded. Context.args contains any
    remaining arguments while parsing.
  • Parameter.add_to_parser (on both Argument and Option) is

• Option.show_envvar now also shows environment variable in error messages.
  :issue:2695 :pr:2696

• Context.close will be called on exit. This results in all
  Context.call_on_close callbacks and context managers added via
  Context.with_resource to be closed on exit as well. :pr:2680

    raises an exception.
  • Ensure to always close the pipe to the pager process and wait for it
    to terminate.
  • echo_via_pager will not ignore KeyboardInterrupt anymore. This
    allows the user to search for future output of the generator when
    using less and then aborting the program using ctrl-c.

• deprecated: bool | str can now be used on options and arguments. This
  previously was only available for Command. The message can now also be
  customised by using a str instead of a bool. :issue:2263 :pr:2271

  • Command.deprecated formatting in --help changed from
    (Deprecated) help to help (DEPRECATED).
  • Parameters cannot be required nor prompted or an error is raised.
  • A warning will be printed when something deprecated is used.

• Add a catch_exceptions parameter to CliRunner. If
  catch_exceptions is not passed to CliRunner.invoke, the value
  from CliRunner is used. :issue:2817 :pr:2818

• Option.flag_value will no longer have a default value set based on
  Option.default if Option.is_flag is False. This results in
  Option.default not needing to implement __bool__. :pr:2829

• Incorrect click.edit typing has been corrected. :pr:2804

• Choice is now generic and supports any iterable value.
  This allows you to use enums and other non-str values. :pr:2796

v1.18.1

Compare Source

We’ve just uploaded mypy 1.18.1 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.

Mypy Performance Improvements

Mypy 1.18.1 includes numerous performance improvements, resulting in about 40% speedup
compared to 1.17 when type checking mypy itself. In extreme cases, the improvement
can be 10x or higher. The list below is an overview of the various mypy optimizations.
Many mypyc improvements (discussed in a separate section below) also improve performance.

Type caching optimizations have a small risk of causing regressions. When
reporting issues with unexpected inferred types, please also check if
--disable-expression-cache will work around the issue, as it turns off some of
these optimizations.

• Improve self check performance by 1.8% (Jukka Lehtosalo, PR 19768, 19769, 19770)
• Optimize fixed-format deserialization (Ivan Levkivskyi, PR 19765)
• Use macros to optimize fixed-format deserialization (Ivan Levkivskyi, PR 19757)
• Two additional micro‑optimizations (Ivan Levkivskyi, PR 19627)
• Another set of micro‑optimizations (Ivan Levkivskyi, PR 19633)
• Cache common types (Ivan Levkivskyi, PR 19621)
• Skip more method bodies in third‑party libraries for speed (Ivan Levkivskyi, PR 19586)
• Simplify the representation of callable types (Ivan Levkivskyi, PR 19580)
• Add cache for types of some expressions (Ivan Levkivskyi, PR 19505)
• Use cache for dictionary expressions (Ivan Levkivskyi, PR 19536)
• Use cache for binary operations (Ivan Levkivskyi, PR 19523)
• Cache types of type objects (Ivan Levkivskyi, PR 19514)
• Avoid duplicate work when checking boolean operations (Ivan Levkivskyi, PR 19515)
• Optimize generic inference passes (Ivan Levkivskyi, PR 19501)
• Speed up the default plugin (Jukka Lehtosalo, PRs 19385 and 19462)
• Remove nested imports from the default plugin (Ivan Levkivskyi, PR 19388)
• Micro‑optimize type expansion (Jukka Lehtosalo, PR 19461)
• Micro‑optimize type indirection (Jukka Lehtosalo, PR 19460)
• Micro‑optimize the plugin framework (Jukka Lehtosalo, PR 19464)
• Avoid temporary set creation in subtype checking (Jukka Lehtosalo, PR 19463)
• Subtype checking micro‑optimization (Jukka Lehtosalo, PR 19384)
• Return early where possible in subtype check (Stanislav Terliakov, PR 19400)
• Deduplicate some types before joining (Stanislav Terliakov, PR 19409)
• Speed up type checking by caching argument inference context (Jukka Lehtosalo, PR 19323)
• Optimize binding method self argument type and deprecation checks (Ivan Levkivskyi, PR 19556)
• Keep trivial instance types/aliases during expansion (Ivan Levkivskyi, PR 19543)

Fixed‑Format Cache (Experimental)

Mypy now supports a new cache format used for faster incremental builds. It makes
incremental builds up to twice as fast. The feature is experimental and
currently only supported when using a compiled version of mypy. Use --fixed-format-cache
to enable the new format, or fixed_format_cache = True in a configuration file.

We plan to enable this by default in a future mypy release, and we'll eventually
deprecate and remove support for the original JSON-based format.

Unlike the JSON-based cache format, the new binary format is currently
not easy to parse and inspect by mypy users. We are planning to provide a tool to
convert fixed-format cache files to JSON, but details of the output JSON may be
different from the current JSON format. If you rely on being able to inspect
mypy cache files, we recommend creating a GitHub issue and explaining your use
case, so that we can more likely provide support for it. (Using
MypyFile.read(binary_data) to inspect cache data may be sufficient to support
some use cases.)

This feature was contributed by Ivan Levkivskyi (PR 19668, 19735, 19750, 19681, 19752, 19815).

Flexible Variable Definitions: Update

Mypy 1.16.0 introduced --allow-redefinition-new, which allows redefining variables
with different types, and inferring union types for variables from multiple assignments.
The feature is now documented in the --help output, but the feature is still experimental.

We are planning to enable this by default in mypy 2.0, and we will also deprecate the
older --allow-redefinition flag. Since the new behavior differs significantly from
the older flag, we encourage users of --allow-redefinition to experiment with
--allow-redefinition-new and create a GitHub issue if the new functionality doesn't
support some important use cases.

This feature was contributed by Jukka Lehtosalo.

Inferred Type for Bare ClassVar

A ClassVar without an explicit type annotation now causes the type of the variable
to be inferred from the initializer:

from typing import ClassVar

class Item:
    # Type of 'next_id' is now 'int' (it was 'Any')
    next_id: ClassVar = 1

    ...

This feature was contributed by Ivan Levkivskyi (PR 19573).

Disjoint Base Classes (@​disjoint_base, PEP 800)

Mypy now understands disjoint bases (PEP 800): it recognizes the @disjoint_base
decorator, and rejects class definitions that combine mutually incompatible base classes,
and takes advantage of the fact that such classes cannot exist in reachability and
narrowing logic.

This class definition will now generate an error:

# Error: Class "Bad" has incompatible disjoint bases
class Bad(str, Exception):
    ...

This feature was contributed by Jelle Zijlstra (PR 19678).

Miscellaneous New Mypy Features

• Add --strict-equality-for-none to flag non-overlapping comparisons involving None (Christoph Tyralla, PR 19718)
• Don’t show import‑related errors after a module‑level assert such as assert sys.platform == "linux" that is always false (Stanislav Terliakov, PR 19347)

Improvements to Match Statements

• Add temporary named expressions for match subjects (Stanislav Terliakov, PR 18446)
• Fix unwrapping of assignment expressions in match subject (Marc Mueller, PR 19742)
• Omit errors for class patterns against object (Marc Mueller, PR 19709)
• Remove unnecessary error for certain match class patterns (Marc Mueller, PR 19708)
• Use union type for captured vars in or pattern (Marc Mueller, PR 19710)
• Prevent final reassignment inside match case (Omer Hadari, PR 19496)

Fixes to Crashes

• Fix crash with variadic tuple arguments to a generic type (Randolf Scholz, PR 19705)
• Fix crash when enable_error_code in pyproject.toml has wrong type (wyattscarpenter, PR 19494)
• Prevent crash for dataclass with PEP 695 TypeVarTuple on Python 3.13+ (Stanislav Terliakov, PR 19565)
• Fix crash on settable property alias (Ivan Levkivskyi, PR 19615)

Experimental Free-threading Support for Mypyc

All mypyc tests now pass on free-threading Python 3.14 release candidate builds. The performance
of various micro-benchmarks scale well across multiple threads.

Free-threading support is still experimental. Note that native attribute access
(get and set), list item access and certain other operations are still
unsafe when there are race conditions. This will likely change in the future.
You can follow the
area-free-threading label
in the mypyc issues tracker to follow progress.

• Enable free‑threading when compiling multiple modules (Jukka Lehtosalo, PR 19541)
• Fix list.pop on free‑threaded builds (Jukka Lehtosalo, PR 19522)
• Make type objects immortal under free‑threading (Jukka Lehtosalo, PR 19538)

Mypyc: Support __new__

Mypyc now has rudimentary support for user-defined __new__ methods.

This feature was contributed by Piotr Sawicki (PR 19739).

Mypyc: Faster Generators and Async Functions

Generators and calls of async functions are now faster, sometimes by 2x or more.

Related PRs:

• Speed up for loops over native generators (Jukka Lehtosalo, PR 19415)
• Speed up native‑to‑native calls using await (Jukka Lehtosalo, PR 19398)
• Call generator helper directly in await expressions (Jukka Lehtosalo, PR 19376)
