class ChatPermissions(TelegramObject):
    """Describes actions that a non-administrator user is allowed to take in a chat.

    Objects of this class are comparable in terms of equality. Two objects of this class are
    considered equal, if their :attr:`can_send_messages`, :attr:`can_send_media_messages`,
    :attr:`can_send_polls`, :attr:`can_send_other_messages`, :attr:`can_add_web_page_previews`,
    :attr:`can_change_info`, :attr:`can_invite_users`, :attr:`can_pin_messages`, and
    :attr:`can_manage_topics` are equal.

    .. versionchanged:: 20.0
        :attr:`can_manage_topics` is considered as well when comparing objects of
        this type in terms of equality.
    .. deprecated:: 20.1
        :attr:`can_send_audios`, :attr:`can_send_documents`, :attr:`can_send_photos`,
        :attr:`can_send_videos`, :attr:`can_send_video_notes` and :attr:`can_send_voice_notes`
        will be considered as well when comparing objects of this type in terms of equality in
        V21.

    Note:
        Though not stated explicitly in the official docs, Telegram changes not only the
        permissions that are set, but also sets all the others to :obj:`False`. However, since not
        documented, this behavior may change unbeknown to PTB.

    Args:
        can_send_messages (:obj:`bool`, optional): :obj:`True`, if the user is allowed to send text
            messages, contacts, locations and venues.

            send audios, documents, photos, videos, video notes and voice notes, implies
            :attr:`can_send_messages`.

            .. deprecated:: 20.1
               Bot API 6.5 replaced this argument with granular media settings.
        can_send_polls (:obj:`bool`, optional): :obj:`True`, if the user is allowed to send polls,
            implies :attr:`can_send_messages`.
        can_send_other_messages (:obj:`bool`, optional): :obj:`True`, if the user is allowed to
            send animations, games, stickers and use inline bots, implies

        can_add_web_page_previews (:obj:`bool`, optional): :obj:`True`, if the user is allowed to
            add web page previews to their messages, implies :attr:`can_send_media_messages`.
        can_change_info (:obj:`bool`, optional): :obj:`True`, if the user is allowed to change the
            chat title, photo and other settings. Ignored in public supergroups.
