 Finding something to do
-#######################
+=======================
 
 If you already know what you'd like to work on, you can skip this section.
 
 If you have an idea for something to do, first check if it's already been filed on the `issue tracker`_. If so, add a comment to the issue saying you'd like to work on it, and we'll help you get started! Otherwise, please file a new issue and assign yourself to it.
 
-Another great way to start contributing is by writing tests. Tests are really important because they help prevent developers from accidentally breaking existing code, allowing them to build cool things faster. If you're interested in helping out, let the development team know by posting to the `Telegram group`_ (use `@admins` to mention the maintainers), and we'll help you get started.

If you're interested in helping out, let the development team know by posting to the `Telegram group`_, and we'll help you get started.
 
 That being said, we want to mention that we are very hesitant about adding new requirements to our projects. If you intend to do this, please state this in an issue and get a verification from one of the maintainers.
 
 Instructions for making a code change
-#####################################
+=====================================
 
 The central development branch is ``master``, which should be clean and ready for release at any time. In general, all changes should be done as feature branches based off of ``master``.
 
+If you want to do solely documentation changes, base them and PR to the branch ``doc-fixes``. This branch also has its own `RTD build`_.
+
 Here's how to make a one-off code change.
 
 1. **Choose a descriptive branch name.** It should be lowercase, hyphen-separated, and a noun describing the change (so, ``fuzzy-rules``, but not ``implement-fuzzy-rules``). Also, it shouldn't start with ``hotfix`` or ``release``.

 3. **Make a commit to your feature branch**. Each commit should be self-contained and have a descriptive commit message that helps other developers understand why the changes were made.
+   We also have a check-list for PRs `below`_.
 
    - You can refer to relevant issues in the commit message by writing, e.g., "#105".
 
    - Your code should adhere to the `PEP 8 Style Guide`_, with the exception that we have a maximum line length of 99.
-   
-   - Document your code. This project uses `sphinx`_ to generate static HTML docs. To build them, first make sure you have the required dependencies:
 
-     .. code-block:: bash
+   - Provide static typing with signature annotations. The documentation of `MyPy`_ will be a good start, the cheat sheet is `here`_. We also have some custom type aliases in ``telegram._utils.types``.
 
-        $ pip install -r docs/requirements-docs.txt
+   - Document your code. This step is pretty important to us, so it has its own `section`_.
 
-     then run the following from the PTB root directory:
-   
-     .. code-block:: bash

If you'd like to leverage that, please have a look at the `pre-commit config file`_ for an overview of which tools (and which versions of them) are used. For example, we use `Black`_ for code formatting. Plugins for Black exist for some `popular editors`_. You can use those instead of manually formatting everything.

+
+Documenting
+===========
+
+The documentation of this project is separated in two sections: User facing and dev facing.
+
+User facing docs are hosted at `RTD`_. They are the main way the users of our library are supposed to get information about the objects. They don't care about the internals, they just want to know
+what they have to pass to make it work, what it actually does. You can/should provide examples for non obvious cases (like the Filter module), and notes/warnings.
+
+Dev facing, on the other side, is for the devs/maintainers of this project. These
+doc strings don't have a separate documentation site they generate, instead, they document the actual code.
+
+User facing documentation
+-------------------------
+We use `sphinx`_ to generate static HTML docs. To build them, first make sure you're running Python 3.9 or above and have the required dependencies:
+
+.. code-block:: bash
+
+   $ pip install -r docs/requirements-docs.txt
+
+then run the following from the PTB root directory:
+
+.. code-block:: bash
+
+   $ make -C docs html
+
+or, if you don't have ``make`` available (e.g. on Windows):
+
+.. code-block:: bash
+
+   $ sphinx-build docs/source docs/build/html
+
+Once the process terminates, you can view the built documentation by opening ``docs/build/html/index.html`` with a browser.
+
+- Add ``.. versionadded:: NEXT.VERSION``, ``.. versionchanged:: NEXT.VERSION`` or ``.. deprecated:: NEXT.VERSION`` to the associated documentation of your changes, depending on what kind of change you made. This only applies if the change you made is visible to an end user. The directives should be added to class/method descriptions if their general behaviour changed and to the description of all arguments & attributes that changed.
+
+Dev facing documentation
+------------------------
+We adhere to the `CSI`_ standard. This documentation is not fully implemented in the project, yet, but new code changes should comply with the `CSI` standard.
+The idea behind this is to make it very easy for you/a random maintainer or even a totally foreign person to drop anywhere into the code and more or less immediately understand what a particular line does. This will make it easier
+for new to make relevant changes if said lines don't do what they are supposed to.

+This library provides a pure Python, asynchronous interface for the
 `Telegram Bot API <https://core.telegram.org/bots/api>`_.
-It's compatible with Python versions 3.5+ and `PyPy <http://pypy.org/>`_.
+It's compatible with Python versions **3.8+**.
 
 In addition to the pure API implementation, this library features a number of high-level classes to
 make the development of bots easy and straightforward. These classes are contained in the
 ``telegram.ext`` submodule.
 
-====================
+A pure API implementation *without* ``telegram.ext`` is available as the standalone package ``python-telegram-bot-raw``.  `See here for details. <https://github.com/python-telegram-bot/python-telegram-bot/blob/master/README_RAW.rst>`_
+
+Note
+----
+
+Installing both ``python-telegram-bot`` and ``python-telegram-bot-raw`` in conjunction will result in undesired side-effects, so only install *one* of both.
+
 Telegram API support
 ====================
 
-All types and methods of the Telegram Bot API **4.8** are supported.
+All types and methods of the Telegram Bot API **6.7** are supported.

+Verifying Releases
+------------------
 
-    $ git submodule update --init --recursive
+We sign all the releases with a GPG key.
+The signatures are uploaded to both the `GitHub releases page <https://github.com/python-telegram-bot/python-telegram-bot/releases>`_ and the `PyPI project <https://pypi.org/project/python-telegram-bot/>`_ and end with a suffix ``.asc``.
+Please find the public keys `here <https://github.com/python-telegram-bot/python-telegram-bot/tree/master/public_keys>`_.
+The keys are named in the format ``<first_version>-<last_version>.gpg`` or ``<first_version>-current.gpg`` if the key is currently being used for new releases.
 
-===============
-Getting started
-===============
+In addition, the GitHub release page also contains the sha1 hashes of the release files in the files with the suffix ``.sha1``.

+Dependencies & Their Versions
+-----------------------------
 
-Other references:
+``python-telegram-bot`` tries to use as few 3rd party dependencies as possible.
+However, for some features using a 3rd party library is more sane than implementing the functionality again.
+As these features are *optional*, the corresponding 3rd party dependencies are not installed by default.
+Instead, they are listed as optional dependencies.
+This allows to avoid unnecessary dependency conflicts for users who don't need the optional features.
 
-- `Telegram API documentation <https://core.telegram.org/bots/api>`_
-- `python-telegram-bot documentation <https://python-telegram-bot.readthedocs.io/>`_
+The only required dependency is `httpx ~= 0.24.1 <https://www.python-httpx.org>`_ for
+``telegram.request.HTTPXRequest``, the default networking backend.
 
--------------------
-Learning by example
--------------------
+``python-telegram-bot`` is most useful when used along with additional libraries.
+To minimize dependency conflicts, we try to be liberal in terms of version requirements on the (optional) dependencies.
+On the other hand, we have to ensure stability of ``python-telegram-bot``, which is why we do apply version bounds.
+If you encounter dependency conflicts due to these bounds, feel free to reach out.
 
-We believe that the best way to learn this package is by example. Here
-are some examples for you to review. Even if it is not your approach for learning, please take a
-look at ``echobot2``, it is the de facto base for most of the bots out there. Best of all,
-the code for these examples are released to the public domain, so you can start by grabbing the

+Concurrency
+===========
 
+Since v20.0, ``python-telegram-bot`` is built on top of Pythons ``asyncio`` module.
+Because ``asyncio`` is in general single-threaded, ``python-telegram-bot`` does currently not aim to be thread-safe.
+Noteworthy parts of ``python-telegram-bots`` API that are likely to cause issues (e.g. race conditions) when used in a multi-threaded setting include:
 
+* ``telegram.ext.Application/Updater.update_queue``
+* ``telegram.ext.ConversationHandler.check/handle_update``
+* ``telegram.ext.CallbackDataCache``
+* ``telegram.ext.BasePersistence``
+* all classes in the ``telegram.ext.filters`` module that allow to add/remove allowed users/chats at runtime

+
+Introduction
+============
+
+This library provides a pure Python, asynchronous interface for the
+`Telegram Bot API <https://core.telegram.org/bots/api>`_.
+It's compatible with Python versions **3.8+**.
+
+``python-telegram-bot-raw`` is part of the `python-telegram-bot <https://python-telegram-bot.org>`_ ecosystem and provides the pure API functionality extracted from PTB. It therefore does not have independent release schedules, changelogs or documentation.
+
+Note
+----
+
+Installing both ``python-telegram-bot`` and ``python-telegram-bot-raw`` in conjunction will result in undesired side-effects, so only install *one* of both.
+
+Telegram API support
+====================
+
+All types and methods of the Telegram Bot API **6.7** are supported.
+
+Installing
+==========
+
+You can install or upgrade ``python-telegram-bot`` via
+
+.. code:: shell
+
+    $ pip install python-telegram-bot-raw --upgrade
+
+To install a pre-release, use the ``--pre`` `flag <https://pip.pypa.io/en/stable/cli/pip_install/#cmdoption-pre>`_ in addition.
+
+You can also install ``python-telegram-bot-raw`` from source, though this is usually not necessary.
+
+.. code:: shell
+
+    $ git clone https://github.com/python-telegram-bot/python-telegram-bot
+    $ cd python-telegram-bot
+    $ python setup-raw.py install
+
+Note
+----
+
+Installing the ``.tar.gz`` archive available on PyPi directly via ``pip`` will *not* work as expected, as ``pip`` does not recognize that it should use ``setup-raw.py`` instead of ``setup.py``.
+
+Verifying Releases
+------------------
+
+We sign all the releases with a GPG key.
+The signatures are uploaded to both the `GitHub releases page <https://github.com/python-telegram-bot/python-telegram-bot/releases>`_ and the `PyPI project <https://pypi.org/project/python-telegram-bot/>`_ and end with a suffix ``.asc``.
+Please find the public keys `here <https://github.com/python-telegram-bot/python-telegram-bot/tree/master/public_keys>`_.
+The keys are named in the format ``<first_version>-<last_version>.gpg`` or ``<first_version>-current.gpg`` if the key is currently being used for new releases.
+
+In addition, the GitHub release page also contains the sha1 hashes of the release files in the files with the suffix ``.sha1``.
+
+This allows you to verify that a release file that you downloaded was indeed provided by the ``python-telegram-bot`` team.
+
+Dependencies & Their Versions
+-----------------------------
+
+``python-telegram-bot`` tries to use as few 3rd party dependencies as possible.
+However, for some features using a 3rd party library is more sane than implementing the functionality again.
+As these features are *optional*, the corresponding 3rd party dependencies are not installed by default.
+Instead, they are listed as optional dependencies.
+This allows to avoid unnecessary dependency conflicts for users who don't need the optional features.
+
+The only required dependency is `httpx ~= 0.24.1 <https://www.python-httpx.org>`_ for
+``telegram.request.HTTPXRequest``, the default networking backend.
+
+``python-telegram-bot`` is most useful when used along with additional libraries.
+To minimize dependency conflicts, we try to be liberal in terms of version requirements on the (optional) dependencies.
+On the other hand, we have to ensure stability of ``python-telegram-bot``, which is why we do apply version bounds.
+If you encounter dependency conflicts due to these bounds, feel free to reach out.
+
+Optional Dependencies
+#####################
+
+PTB can be installed with optional dependencies:
+
+* ``pip install "python-telegram-bot-raw[passport]"`` installs the `cryptography>=39.0.1 <https://cryptography.io/en/stable>`_ library. Use this, if you want to use Telegram Passport related functionality.
+* ``pip install "python-telegram-bot-raw[socks]"`` installs `httpx[socks] <https://www.python-httpx.org/#dependencies>`_. Use this, if you want to work behind a Socks5 server.
+* ``pip install "python-telegram-bot-raw[http2]"`` installs `httpx[http2] <https://www.python-httpx.org/#dependencies>`_. Use this, if you want to use HTTP/2.
+
+To install multiple optional dependencies, separate them by commas, e.g. ``pip install "python-telegram-bot-raw[passport,socks]"``.
+
+Additionally, the shortcut ``pip install "python-telegram-bot-raw[all]"`` installs all optional dependencies.

+Examples
+========
+
+In this section we display small examples to show what a bot written with
+``python-telegram-bot`` looks like.
+Some bots focus on one specific
+aspect of the Telegram Bot API while others focus on one of the
+mechanics of this library. Except for the
+:any:`examples.rawapibot` example, they all use the high-level
+framework this library provides with the
+:mod:`telegram.ext` submodule.
+
+All examples are licensed under the `CC0
+License <https://github.com/python-telegram-bot/python-telegram-bot/blob/master/examples/LICENSE.txt>`__
+and are therefore fully dedicated to the public domain. You can use them
+as the base for your own bots without worrying about copyrights.
+
+Do note that we ignore one pythonic convention. Best practice would
+dictate, in many handler callbacks function signatures, to replace the
+argument ``context`` with an underscore, since ``context`` is an unused
+local variable in those callbacks. However, since these are examples and
+not having a name for that argument confuses beginners, we decided to
+have it present.
+
+:any:`examples.echobot`
+-----------------------
+
+This is probably the base for most of the bots made with
+``python-telegram-bot``. It simply replies to each text message with a
+message that contains the same text.
+
+:any:`examples.timerbot`
+------------------------
+
+This bot uses the
+:class:`telegram.ext.JobQueue`
+class to send timed messages. The user sets a timer by using ``/set``
+command with a specific time, for example ``/set 30``. The bot then sets
+up a job to send a message to that user after 30 seconds. The user can
+also cancel the timer by sending ``/unset``. To learn more about the
+``JobQueue``, read `this wiki article <https://github.com/python-telegram-bot/python-telegram-bot/wiki/Extensions---JobQueue>`__.
+Note: To use ``JobQueue``, you must install PTB via ``pip install "python-telegram-bot[job-queue]"``
+
+:any:`examples.conversationbot`
+-------------------------------
+
+A common task for a bot is to ask information from the user. In v5.0 of
+this library, we introduced the
+:class:`telegram.ext.ConversationHandler`
+for that exact purpose. This example uses it to retrieve
+user-information in a conversation-like style. To get a better
+understanding, take a look at the :ref:`state diagram <conversationbot-diagram>`.
+
+:any:`examples.conversationbot2`
+--------------------------------
+
+A more complex example of a bot that uses the ``ConversationHandler``.
+It is also more confusing. Good thing there is a :ref:`fancy state diagram <conversationbot2-diagram>`.
+for this one, too!
+
+:any:`examples.nestedconversationbot`
+-------------------------------------
+
+A even more complex example of a bot that uses the nested
+``ConversationHandler``\ s. While it’s certainly not that complex that
+you couldn’t built it without nested ``ConversationHanldler``\ s, it
+gives a good impression on how to work with them. Of course, there is a
+:ref:`fancy state diagram <nestedconversationbot-diagram>`
+for this example, too!
+
+:any:`examples.persistentconversationbot`
+-----------------------------------------
+
+A basic example of a bot store conversation state and user_data over
+multiple restarts.
+
+:any:`examples.inlinekeyboard`
+------------------------------
+
+This example sheds some light on inline keyboards, callback queries and
+message editing. A wiki site explaining this examples lives
+`here <https://github.com/python-telegram-bot/python-telegram-bot/wiki/InlineKeyboard-Example>`__.
+
+:any:`examples.inlinekeyboard2`
+-------------------------------
+
+A more complex example about inline keyboards, callback queries and
+message editing. This example showcases how an interactive menu could be
+build using inline keyboards.
+
+:any:`examples.deeplinking`
+---------------------------
+
+A basic example on how to use deeplinking with inline keyboards.
+
+:any:`examples.inlinebot`
+-------------------------
+
+A basic example of an `inline
+bot <https://core.telegram.org/bots/inline>`__. Don’t forget to enable
+inline mode with `@BotFather <https://telegram.me/BotFather>`_.
+
+:any:`examples.pollbot`
+-----------------------
+
+This example sheds some light on polls, poll answers and the
+corresponding handlers.
+
+:any:`examples.passportbot`
+---------------------------
+
+A basic example of a bot that can accept passports. Use in combination
+with the :ref:`HTML page <passportbot-html>`.
+Don’t forget to enable and configure payments with
+`@BotFather <https://telegram.me/BotFather>`_. Check out this
+`guide <https://github.com/python-telegram-bot/python-telegram-bot/wiki/Telegram-Passport>`__
+on Telegram passports in PTB.
+Note: To use Telegram Passport, you must install PTB via ``pip install "python-telegram-bot[passport]"``
+
+:any:`examples.paymentbot`
+--------------------------
+
+A basic example of a bot that can accept payments. Don’t forget to
+enable and configure payments with
+`@BotFather <https://telegram.me/BotFather>`_.
+
+:any:`examples.errorhandlerbot`
+-------------------------------
+
+A basic example on how to set up a custom error handler.
+
+:any:`examples.chatmemberbot`
+-----------------------------
+
+A basic example on how ``(my_)chat_member`` updates can be used.
+
+:any:`examples.webappbot`
+-------------------------
+
+A basic example of how `Telegram
+WebApps <https://core.telegram.org/bots/webapps>`__ can be used. Use in
+combination with the :ref:`HTML page <webappbot-html>`.
+For your convenience, this file is hosted by the PTB team such that you
+don’t need to host it yourself. Uses the
+`iro.js <https://iro.js.org>`__ JavaScript library to showcase a
+user interface that is hard to achieve with native Telegram
+functionality.
+
+:any:`examples.contexttypesbot`
+-------------------------------
+
+This example showcases how ``telegram.ext.ContextTypes`` can be used to
+customize the ``context`` argument of handler and job callbacks.
+
+:any:`examples.customwebhookbot`
+--------------------------------
+
+This example showcases how a custom webhook setup can be used in
+combination with ``telegram.ext.Application``.
+
+:any:`examples.arbitrarycallbackdatabot`
+----------------------------------------
+
+This example showcases how PTBs “arbitrary callback data” feature can be
+used.
+Note: To use arbitrary callback data, you must install PTB via ``pip install "python-telegram-bot[callback-data]"``
+
+Pure API
+--------
+
+The :any:`examples.rawapibot` example example uses only the pure, “bare-metal” API wrapper.

+    Instead, you can manually call the methods listed below to start and shut down the application

+Stability Policy
+================
+
+.. important::
+
+    This stability policy is in place since version 20.3.
+    While earlier versions of ``python-telegram-bot`` also had stable interfaces, they had no explicit stability policy and hence did not follow the rules outlined below in all detail.
+    Please also refer to the :ref:`changelog <ptb-changelog>`.
+
+.. caution::
+
+    Large parts of the :mod:`telegram` package are the Python representations of the Telegram Bot API, whose stability policy PTB can not influence.
+    This policy hence includes some special cases for those parts.
+
+What does this policy cover?
+----------------------------
+
+This policy includes any API or behavior that is covered in this documentation.
+This covers both the :mod:`telegram` package and the :mod:`telegram.ext` package.
+
+What doesn't this policy cover?
+-------------------------------
+
+Introduction of new features or changes of flavors of comparable behavior (e.g. the default for the HTTP protocol version being used) are not covered by this policy.
+
+The internal structure of classes in PTB, i.e. things like the result of ``dir(obj))`` or the contents of ``obj.__dict__``, is not covered by this policy.
+
+Objects are in general not guaranteed to be pickleable (unless stated otherwise) and pickled objects from one version of PTB may not be loadable in future versions.
+We may provide a way to convert pickled objects from one version to another, but this is not guaranteed.
+
+Functionality that is part of PTBs API but is explicitly documented as not being intended to be used directly by users (e.g. :meth:`telegram.request.BaseRequest.do_request`) may change.
+This also applies to functions or attributes marked as final in the sense of `PEP 591 <https://peps.python.org/pep-0591/>`__.
+
+PTB has dependencies to third-party packages.
+The versions that PTB uses of these third-party packages may change if that does not affect PTBs public API.
+
+PTB does not give guarantees about which Python versions are supported.
+In general, we will try to support all Python versions that have not yet reached their end of life, but we reserve ourselves the option to drop support for Python versions earlier if that benefits the advancement of the library.
+
+PTB provides static type hints for all public attributes, parameters, return values and generic classes.
+These type hints are not covered by this policy and may change at any time under the condition that these changes have no impact on the runtime behavior of PTB.
+
+.. _bot-api-functionality-1:
+
+Bot API Functionality
+~~~~~~~~~~~~~~~~~~~~~
+
+Comparison of equality of instances of the classes in the :mod:`telegram` package is subject to change and the PTB team will update the behavior to best reflect updates in the Bot API.
+Changes in this regard will be documented in the affected classes.
+Note that equality comparison with objects that where serialized by an older version of PTB may hence give unexpected results.
+
+When the order of arguments of the Bot API methods changes or they become optional/mandatory due to changes in the Bot API, PTB will always try to reflect these changes.
+While we try to make such changes backward compatible, this is not always possible or only with significant effort.
+In such cases we will find a trade-off between backward compatibility and fully complying with the Bot API, which may result in breaking changes.
+We highly recommend using keyword arguments, which can help make such changes non-breaking on your end.
+
+..
+    We have documented a few common cases and possible backwards compatible solutions in the wiki as a reference for the dev team: https://github.com/python-telegram-bot/python-telegram-bot/wiki/Bot-API-Backward-Compatibility
+
+When the Bot API changes attributes of classes, the method :meth:`telegram.TelegramObject.to_dict` will change as necessary to reflect these changes.
+In particular, attributes deprecated by Telegram will be removed from the returned dictionary.
+Deprecated attributes that are still passed by Telegram will be available in the :attr:`~telegram.TelegramObject.api_kwargs` dictionary as long as PTB can support that with feasible effort.
+Since attributes of the classes in the :mod:`telegram` package are not writable, we may change them to properties where appropriate.
+
+Development Versions
+~~~~~~~~~~~~~~~~~~~~
+
+Pre-releases marked as alpha, beta or release candidate are not covered by this policy.
+Before a feature is in a stable release, i.e. the feature was merged into the ``master`` branch but not released yet (or only in a pre-release), it is not covered by this policy either and may change.
+
+Security
+~~~~~~~~
+
+We make exceptions from our stability policy for security.
+We will violate this policy as necessary in order to resolve a security issue or harden PTB against a possible attack.
+
+Versioning
+----------
+
+PTB uses a versioning scheme that roughly follows `https://semver.org/ <https://semver.org/>`_, although it may not be quite as strict.
+
+Given a version of PTB X.Y.Z,
+
+-  X indicates the major version number.
+   This is incremented when backward incompatible changes are introduced.
+-  Y indicates the minor version number.
+   This is incremented when new functionality or backward compatible changes are introduced by PTB.
+   *This is also incremented when PTB adds support for a new Bot API version, which may include backward incompatible changes in some cases as outlined* :ref:`below <bot-api-versioning>`.
+-  Z is the patch version.
+   This is incremented if backward compatible bug fixes or smaller changes are introduced.
+   If this number is 0, it can be omitted, i.e. we just write X.Y instead of X.Y.0.
+
+Deprecation
+~~~~~~~~~~~
+
+From time to time we will want to change the behavior of an API or remove it entirely, or we do so to comply with changes in the Telegram Bot API.
+In those cases, we follow a deprecation schedule as detailed below.
+
+Functionality is marked as deprecated by a corresponding note in the release notes and the documentation.
+Where possible, a :class:`~telegram.warnings.PTBDeprecationWarning` is issued when deprecated functionality is used, but this is not mandatory.
+
+From time to time, we may decide to deprecate an API that is particularly widely used.
+In these cases, we may decide to provide an extended deprecation period, at our discretion.
+
+With version 20.0.0, PTB introduced major structural breaking changes without the above deprecation period.
+Should a similarly big change ever be deemed necessary again by the development team and should a deprecation period prove too much additional effort, this violation of the stability policy will be announced well ahead of the release in our channel, `as was done for v20 <https://t.me/pythontelegrambotchannel/94>`_.
+
+Non-Bot API Functionality
+#########################
+
+Starting with version 20.3, deprecated functionality will stay available for the current and the next major version.
+For example:
+
+-  In PTB v20.1.1 the feature exists
+-  In PTB v20.1.2 or v20.2.0 the feature is marked as deprecated
+-  In PTB v21.*.* the feature is marked as deprecated
+-  In PTB v22.0 the feature is removed or changed
+
+.. _bot-api-versioning:
+
+Bot API Functionality
+#####################
+
+As PTB has no control over deprecations introduced by Telegram and the schedule of these deprecations rarely coincides with PTBs deprecation schedule, we have a special policy for Bot API functionality.
+
+Starting with 20.3, deprecated Bot API functionality will stay available for the current and the next major version of PTB *or* until the next version of the Bot API.
+More precisely, two cases are possible, for which we show examples below.
+
+Case 1
+^^^^^^
+
+-  In PTB v20.1 the feature exists
+-  Bot API version 6.6 is released and deprecates the feature
+-  PTB v20.2 adds support for Bot API 6.6 and the feature is
+   marked as deprecated
+-  In PTB v21.0 the feature is removed or changed
+
+Case 2
+^^^^^^
+
+-  In PTB v20.1 the feature exists
+-  Bot API version 6.6 is released and deprecates the feature
+-  PTB v20.2 adds support for Bot API version 6.6 and the feature is marked as deprecated
+-  In PTB v20.2.* and v20.3.* the feature is marked as deprecated
+-  Bot API version 6.7 is released
+-  PTB v20.4 adds support for Bot API version 6.7 and the feature is removed or changed
