Changes

• Fixed the test suite on PyPy3.8 where cloudpickle does not work.
  #​892
• Fixed coverage report for projects that use attrs and don't set a --source.
  #​895,
  #​896

v21.3.0

Compare Source

Backward-incompatible Changes

• When using @define, converters are now run by default when setting an attribute on an instance -- additionally to validators.
  Meaning: the new default is on_setattr=[attrs.setters.convert, attrs.setters.validate].

  This is unfortunately a breaking change, but it was an oversight, impossible to raise a DeprecationWarning about, and it's better to fix it now while the APIs are very fresh with few users.
  #​835,
  #​886

• import attrs has finally landed!
  As of this release, you can finally import attrs using its proper name.

  Not all names from the attr namespace have been transferred; most notably attr.s and attr.ib are missing.
  See attrs.define and attrs.field if you haven't seen our next-generation APIs yet.
  A more elaborate explanation can be found On The Core API Names

  This feature is at least for one release provisional.
  We don't plan on changing anything, but such a big change is unlikely to go perfectly on the first strike.

  The API docs have been mostly updated, but it will be an ongoing effort to change everything to the new APIs.
  Please note that we have not moved -- or even removed -- anything from attr!

  Please do report any bugs or documentation inconsistencies!
  #​887

Changes

• attr.asdict(retain_collection_types=False) (default) dumps collection-esque keys as tuples.
  #​646,
  #​888
• __match_args__ are now generated to support Python 3.10's
  Structural Pattern Matching.
  This can be controlled by the match_args argument to the class decorators on Python 3.10 and later.
  On older versions, it is never added and the argument is ignored.
  #​815
• If the class-level on_setattr is set to attrs.setters.validate (default in @define and @mutable) but no field defines a validator, pretend that it's not set.
  #​817
• The generated __repr__ is significantly faster on Pythons with f-strings.
  #​819
• Attributes transformed via field_transformer are wrapped with AttrsClass again.
  #​824
• Generated source code is now cached more efficiently for identical classes.
  #​828
• Added attrs.converters.to_bool().
  #​830
• attrs.resolve_types() now resolves types of subclasses after the parents are resolved.
  #​842
  #​843
• Added new validators: lt(val) (< val), le(va) (≤ val), ge(val) (≥ val), gt(val) (> val), and maxlen(n).
  #​845
• attrs classes are now fully compatible with cloudpickle (no need to disable repr anymore).
  #​857
• Added new context manager attrs.validators.disabled() and functions attrs.validators.(set|get)_disabled().
  They deprecate attrs.(set|get)_run_validators().
  All functions are interoperable and modify the same internal state.
  They are not – and never were – thread-safe, though.
  #​859
• attrs.validators.matches_re() now accepts pre-compiled regular expressions in addition to pattern strings.
  #​877

v1.17.1

Compare Source

• Fix failing distutils.msvc9compiler imports under Windows (#​118).
• ffibuilder.emit_python_code() and ffibuiler.emit_c_code() accept file-like objects (#​115).
• ffiplatform calls are bypassed by ffibuilder.emit_python_code() and ffibuilder.emit_c_code() (#​81).

Full Changelog: python-cffi/cffi@v1.17.0...v1.17.1

v1.17.0

Compare Source

• Add support for Python 3.13.
  • Free-threaded CPython builds (i.e. python3.13t and the 3.13t ABI) are not currently supported.
• In API mode, when you get a function from a C library by writing
  fn = lib.myfunc, you get an object of a special type for performance
  reasons, instead of a <cdata 'C-function-type'>. Before version 1.17
  you could only call such objects. You could write
  ffi.addressof(lib, "myfunc") in order to get a real <cdata> object,
  based on the idea that in these cases in C you'd usually write &myfunc
  instead of myfunc. In version 1.17, the special object
  lib.myfunc can now be passed in many places where CFFI expects
  a regular <cdata> object. For example, you can now pass
  it as a callback to a C function call, or write it inside a C
  structure field of the correct pointer-to-function type, or use
  ffi.cast() or ffi.typeof() on it.

Full Changelog: python-cffi/cffi@v1.16.0...v1.17.0

v1.16.0

Compare Source

• Add support for Python 3.12. With the removal of distutils from Python 3.12, projects
  using CFFI features that depend on distutils at runtime must add a dependency on
  setuptools to function under Python 3.12+. CFFI does not declare a runtime setuptools
  requirement to avoid an unnecessary dependency for projects that do not require it.
• Drop support for end-of-life Python versions (2.7, 3.6, 3.7).
• Add support for PEP517 builds; setuptools is now a required build dependency.
• Declare python_requires metadata for Python 3.8+. This allows unsupported Pythons
  to continue using previously released sdists and wheels.
• Move project source under src/; a more standard layout that also enables CI to more easily
  catch packaging errors.

v1.15.1

Compare Source

(retroactive GitHub release for current stable version 1.15.1)

• If you call ffi.embedding_api() but don't write any extern "Python" function there, then the resulting C code would fail an assert. Fixed.
• Updated Windows/arm64 embedded libffi static lib to v3.4.2, and scripted to ease future updates (thanks Niyas Sait!)

Released 2026-11-09

• Fix copy.deepcopy() and pickle on a Parameter, Option or Command. {pr}3805
• A KeyboardInterrupt arriving while Command.main() reports an abort or an error,
  or while it exits, no longer escapes as an unhandled traceback. The command still
  exits with the intended code; only the message may be lost. {issue}3802
• Add {meth}Option.get_help_spec, which returns the option's left help
  column even when the option is hidden. {meth}Option.get_help_record still
  returns None for hidden options, so help screens are unchanged. {pr}3821
• The Positional arguments help section lists every argument of the command,
  not only the documented ones. An argument with no help gets an empty
  description, the same way an option with no help does. {pr}3860
• {meth}Argument.get_help_record always returns a tuple. It used to return
  None for an argument with no help. {pr}3860
• Document which types are inferred from default, and what an unrecognized
  type callable does to a command-line value. {issue}3036 {pr}3808
• path_type narrows the converted value's type for convert and prompt.
  {issue}3822 {pr}3858
• {class}Parameter accepts a new help argument and {class}Option and {class}Argument
  inherits it. {meth}Parameter.to_info_dict now reports help for every kind of parameter.
  {pr}3861
• A command's short help no longer stops at an abbreviation such as vs. or e.g.
  inside the first sentence. A period ends the sentence only when it closes the text
  or the next word does not start in lowercase. {pr}3865
• With show_envvar=True, an option's error message now prints all variables of an
  envvar sequence instead of the repr of the sequence. {pr}3884
• An empty envvar, such as [] or "", shows the same help and error message as
  no envvar when show_envvar=True. The help screen used to show [env var: ].
  {pr}3884
• Align command's deprecated help text to options and arguments: do not translate the
  command's own help text, only the (DEPRECATED) label. {pr}3901

v8.5.0

Compare Source

Released 2026-08-24

• Add built-in shell completion support for PowerShell (Windows PowerShell
  5.1+ and pwsh 7+) alongside the existing bash, zsh, and fish
  completers. Use _FOO_BAR_COMPLETE=powershell_source foo-bar to generate
  the completion script. {issue}2672 {pr}3637
• Supported versions of Windows enable ANSI terminal styles by default.
  Colorama is no longer a dependency and is not used. {issue}2986 {pr}3505
• {class}Argument accepts a help parameter, and help output includes
  a Positional arguments section when argument help is available. {issue}2983 {pr}3473
• confirm() and prompt() strip ANSI color and style codes from the
  prompt when the output stream does not support them, matching echo().
  This stripping was lost in 8.4.0 when {pr}2969 began writing the
  prompt with input() directly. {issue}3572 {pr}3653
• Fix test failures when using pytest >= 9.1. {pr}3656
• {class}Path with allow_dash=True no longer triggers a BytesWarning,
  an error under python -bb, when checking a value against the -
  convention. {issue}2877 {pr}3642
• Add {func}custom_version_option, a --version option whose output is
  produced by a callback, covering cases {func}version_option intentionally
  does not. The feature set of {func}version_option is now frozen. {pr}3581
• style() and secho() no longer silently drop the 256-color index 0
  (black) passed as fg or bg, and now validate color arguments. Invalid
  colors raise a ValueError instead of a TypeError. {pr}3677
• The automatic help option stores its value under the reserved name
  _click_default_help instead of help, so a parameter named help no
  longer breaks parsing. The new name is visible in
  {meth}Command.to_info_dict output. Parameters that overwrite each other's
  value trigger a warning: an argument sharing its name with another
  parameter, or any parameter claiming the reserved name. Options may still
  share a name to compete for the same value (feature switches).
  {issue}2819 {pr}3678
• unstyle and the ANSI handling behind help-text wrapping now strip the full
  CSI escape-sequence grammar. {pr}3681
• Streamline Option flag handling: the flag-kind, type, lazy-default and
  validation steps in Option.__init__ move into focused helpers, and
  flag_value and default keep their unset sentinel at construction
  (resolved lazily on read) so is UNSET reliably tells a user-supplied value
  from an auto-derived one. Runtime behavior is unchanged, but
  {meth}Parameter.to_info_dict now resolves default=True on a feature
  switch to its flag_value, matching what the function receives at call
  time. {pr}3641
• {func}get_binary_stream and {func}get_text_stream are deprecated and
  will be removed in Click 9.0. {issue}3481 {pr}3695
• The following click.utils names were never intentionally public and are
  now private (_-prefixed). The old names remain available with a
  DeprecationWarning until Click 9.0: LazyFile, KeepOpenFile,
  make_default_short_help, PacifyFlushWrapper, and safecall.
  {issue}3099 {pr}3695
• Deprecate {meth}CliRunner.isolated_filesystem. It relies on
  {func}os.chdir, which mutates process-global state and is not
  thread-safe. The helper predates Python 3 and modern pytest: use a
  temporary directory ({class}tempfile.TemporaryDirectory or pytest's
  tmp_path fixture) with absolute paths instead. For running tests in
  parallel, use process-based isolation (such as pytest-xdist) rather
  than threads, since {meth}CliRunner.invoke also redirects the
  process-global standard streams. {issue}3501 {issue}3700 {pr}3704
• prompt() is now generically typed and returns the type produced by
  type, value_proc, or a matching default instead of Any.
  {class}ParamType takes a second optional type parameter describing the
  input value it accepts (ParamType[int, str] for a type converting
  strings to integers), defaulting to Any. {pr}3407
• {meth}Command.get_help_option_names returns the help option names in the
  order they were declared. {pr}3728
• {func}get_pager_file yields a text stream on Windows again. The temporary
  file backend opened its file in binary mode, so writing a str to the pager
  raised TypeError: a bytes-like object is required, not 'str', and the
  color argument was ignored on that path. Regression introduced in 8.4.0
  by {pr}1572. {issue}3731 {issue}3732 {issue}3740 {pr}3739
• {func}progressbar settles on its final position when update_min_steps
  does not divide the total. Steps below that threshold are applied when the
  bar finishes, so show_pos renders 20/20 rather than the last multiple
  it reached. {issue}3571 {pr}3769
• An error raised while writing to the pager no longer gets replaced by
  PermissionError: [WinError 32] on Windows. The temporary file backend
  unlinked its file without closing it first, and Windows refuses to remove a
  file the process still holds open, so the cleanup failure masked the real
  exception. {issue}3731 {pr}3764
• The temporary file the pager writes to on Windows is opened with the encoding
  {func}get_pager_file picked for the output stream, and with
  errors="replace" to match the pipe backend. Any text stdout can encode
  reaches the pager.
• The temporary file pager backend forwards any parameters the user set in
  PAGER to the pager command instead of silently dropping them. On Windows,
  PAGER="less -R" now invokes less -R on the temporary file rather than
  bare less. {pr}3777
• Improve raw mode detection by parsing the option tokens. {issue}3416
  {pr}3777
• {func}edit accepts os.PathLike values for filename, in addition to
  strings. {issue}2869 {pr}3781

v8.4.2

Released 2026-06-24

• Fix Fish shell completion broken in 8.4.0 by {pr}3126. Newlines and
  tabs in option help text are now escaped, keeping the original completion
  format while still supporting multi-line help. {issue}3502
  {issue}3043 {pr}3504 {pr}3508
• Deprecated commands and options with empty or missing help text no longer
  render a stray leading space before the (DEPRECATED) label. {pr}3509
• A {class}Group with invoke_without_command=True marks its subcommand as
  optional in the usage help, showing [COMMAND] instead of COMMAND.
  {issue}3059 {pr}3507
• echo_via_pager flushes after each write, so passing a generator streams
  output to the pager incrementally instead of staying hidden until the pipe
  buffer fills. {issue}3242 {issue}2542 {pr}3534
• echo_via_pager and get_pager_file no longer close a borrowed stdout
  stream when no external pager runs, completing the partial
  I/O operation on closed file fix from {pr}3482. {issue}3449
  {pr}3533
• Fix CLI usage symopsis for optional arguments producing double square brackets
  [[a|b|c]]... whose type already brackets their metavar. {pr}3578
• {func}version_option resolves a package_name that does not match an
  installed distribution as an import (top-level module) name via
  {func}importlib.metadata.packages_distributions. Packages whose
  top-level module name differs from their distribution name (PIL vs
  Pillow, jwt vs PyJWT) no longer raise RuntimeError out of the
  box. {issue}2331 {issue}1884 {issue}3125 {pr}3582

Released 2026-05-17

• {class}ParamType typing improvements. {pr}3371

  • {class}ParamType is now a generic abstract base class,
    parameterized by its converted value type.
  • {meth}~ParamType.convert return types are narrowed on all
    concrete types (str for {class}STRING, int for
    {class}INT, etc.).
  • {meth}~ParamType.to_info_dict returns specific
    {class}~typing.TypedDict subclasses instead of
    dict[str, Any].
  • {class}CompositeParamType and the number-range base are now
    generic with abstract methods.

• Refactor convert_type to extract type inference into a private
  _guess_type helper, and add {func}typing.overload signatures.
  {pr}3372

• {class}Parameter typing improvements. {pr}2805

  • {class}Parameter is now an abstract base class, making explicit
    that it cannot be instantiated directly.
  • {attr}Parameter.name is now str instead of str | None.
    When expose_value=False, the name is set to "" instead
    of None.
  • The ctx parameter of {meth}Parameter.get_error_hint is now
    typed as Context | None, matching the runtime behavior.

• Split string values from default_map for parameters with nargs > 1
  or {class}Tuple type, matching environment variable behavior.
  {issue}2745 {pr}3364

• Auto-detect type=UNPROCESSED for flag_value of non-basic types
  (not str, int, float, or bool), so programmer-provided
  Python objects like classes and enum members are passed through unchanged
  instead of being stringified. Previously type=click.UNPROCESSED had
  to be set explicitly. {issue}2012 {pr}3363

• The error hint now uses {meth}Command.get_help_option_names to pick
  non-shadowed help option names, so Try '... -h' no longer points to a
  subcommand option that shadows -h. The longest surviving name is
  shown (--help over -h) for readability. {issue}2790 {pr}3208

• Fix readline functionality on non-Windows platforms. Prompt text is now
  passed directly to readline instead of being printed separately, allowing
  proper backspace, line editing, and line wrapping behavior. {issue}2968
  {pr}2969

• Use {func}os.startfile on Windows to open URLs in {func}open_url,
  replacing the start built-in which cannot be invoked without
  shell=True. {issue}2868 {issue}3164 {pr}3186

• Fix Fish shell completion errors when option help text contains newlines.
  {issue}3043 {pr}3126

• Add {class}NoSuchCommand exception with suggestions for misspelled
  commands. {issue}3107 {pr}3228

• Use {class}ValueError message when conversion in {class}FuncParamType would
  fail. {issue}3105 {pr}3211

• Add click.get_pager_file for file-like access to an output
  pager. {pr}1572 {pr}3405

• {func}~click.formatting.wrap_text now measures line width in visible
  characters, ignoring ANSI escape sequences. {pr}3420

• Fix {meth}HelpFormatter.write_usage emitting only a blank line when
  called without args. The usage prefix and program name are now
  written even when no arguments follow, and the trailing separator
  space is stripped so the line ends at the program name.
  {issue}3360 {pr}3434

• Show custom error messages from types when {func}prompt with
  hide_input=True fails validation, instead of always showing a
  generic message. Built-in type messages mask the input value.
  {issue}2809 {pr}3256

• Add capture parameter to {class}CliRunner with two modes: sys
  (default) and fd. fd redirects file descriptors 1 and 2
  via {func}os.dup2 so output that bypasses sys.stdout (stale stream
  references, C extensions, subprocesses, faulthandler) is captured
  with proper isolation. {issue}854 {issue}2412 {issue}2468
  {issue}2497 {issue}2761 {issue}2827 {issue}2865 {pr}3391

• Revert the 8.3.3 change that exposed the original file descriptor
  via fileno() on the redirected CliRunner streams in the default
  capture mode. os.dup2(w, sys.stdout.fileno()) calls inside a CLI no
  longer mutate the host runner's stdout, which broke Pytest's fd-level
  capture teardown. C-level consumers that need a real fd should use
  capture="fd". {issue}3384 {pr}3391

• Mark additional built-in strings with gettext() to extend translation
  coverage. {pr}2902

• Fix feature switch groups (several flag_value options sharing one
  parameter name) silently dropping an explicit default when a sibling
  option without an explicit default was declared first. Arbitration is now
  source-aware: a more explicit {class}ParameterSource always wins, and
  within ParameterSource.DEFAULT, an option that received an explicit
  default= keyword wins over a sibling whose default was auto-derived.
  The 8.3.x first-wins fallback for remaining ties was reverted to the
  pre-8.3.x last-wins fallback. {issue}3403 {pr}3404

• Fix missing space between option help text and the (DEPRECATED)
  label, and localize the option label so it matches the command label.
  The label and the DeprecationWarning reason suffix are now produced
  by shared helpers. {pr}3423

• Document short option stacking (-abc is parsed as -a -b -c) and
  clarify that multi-character short option names are not supported.

• Fix default=True with boolean flag_value always returning the
  flag_value instead of True. The default=True to flag_value
  substitution now only applies to non-boolean flags, where True acts as a
