 .. currentmodule:: click
 
+Version 8.2.0
+-------------
+
+Unreleased
+
+-   Drop support for Python 3.7. :pr:`2588`
+-   Use modern packaging metadata with ``pyproject.toml`` instead of ``setup.cfg``.
+    :pr:`2438`
+-   Use ``flit_core`` instead of ``setuptools`` as build backend. :pr:`2543`
+-   Deprecate the ``__version__`` attribute. Use feature detection, or
+    ``importlib.metadata.version("click")``, instead. :issue:`2598`
+-   ``BaseCommand`` is deprecated. ``Command`` is the base class for all
+    commands. :issue:`2589`
+-   ``MultiCommand`` is deprecated. ``Group`` is the base class for all group
+    commands. :issue:`2590`
+-   The current parser and related classes and methods, are deprecated.
+    :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
+        unneeded. Parsing works directly without building a separate parser.
+    -   ``split_arg_string`` is moved from ``parser`` to ``shell_completion``.
+
+-   Enable deferred evaluation of annotations with
+    ``from __future__ import annotations``. :pr:`2270`
+-   When generating a command's name from a decorated function's name, the
+    suffixes ``_command``, ``_cmd``, ``_group``, and ``_grp`` are removed.
+    :issue:`2322`
+-   Show the ``types.ParamType.name`` for ``types.Choice`` options within
+    ``--help`` message if ``show_choices=False`` is specified.
+    :issue:`2356`
+-   Do not display default values in prompts when ``Option.show_default`` is
+    ``False``. :pr:`2509`
+-   Add ``get_help_extra`` method on ``Option`` to fetch the generated extra
+    items used in ``get_help_record`` to render help text. :issue:`2516`
+    :pr:`2517`
+-   Keep stdout and stderr streams independent in ``CliRunner``. Always
+    collect stderr output and never raise an exception. Add a new
+    output stream to simulate what the user sees in its terminal. Removes
+    the ``mix_stderr`` parameter in ``CliRunner``. :issue:`2522` :pr:`2523`
+-   ``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`
+-   Add ``ProgressBar(hidden: bool)`` to allow hiding the progressbar. :issue:`2609`
+-   A ``UserWarning`` will be shown when multiple parameters attempt to use the
+    same name. :issue:`2396`
+-   When using ``Option.envvar`` with ``Option.flag_value``, the ``flag_value``
+    will always be used instead of the value of the environment variable.
+    :issue:`2746` :pr:`2788`
+-   Add ``Choice.get_invalid_choice_message`` method for customizing the
+    invalid choice message. :issue:`2621` :pr:`2622`
+-   If help is shown because ``no_args_is_help`` is enabled (defaults to ``True``
+    for groups, ``False`` for commands), the exit code is 2 instead of 0.
+    :issue:`1489` :pr:`1489`
+-   Contexts created during shell completion are closed properly, fixing
+    a ``ResourceWarning`` when using ``click.File``. :issue:`2644` :pr:`2800`
+    :pr:`2767`
+-   ``click.edit(filename)`` now supports passing an iterable of filenames in
+    case the editor supports editing multiple files at once. Its return type
+    is now also typed: ``AnyStr`` if ``text`` is passed, otherwise ``None``.
+    :issue:`2067` :pr:`2068`
+-   Specialized typing of ``progressbar(length=...)`` as ``ProgressBar[int]``.
+    :pr:`2630`
+-   Improve ``echo_via_pager`` behaviour in face of errors.
+    :issue:`2674`
+
+    -   Terminate the pager in case a generator passed to ``echo_via_pager``
+        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``. :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`
+    :issue:`605`
