v0.10.0
-------

For breaking changes, see :ref:`migrating-to-async`. The breaking changes listed there will not be enumerated below.

New Features
~~~~~~~~~~~~~

- The library is now fully ``asyncio`` compatible, allowing you to write non-blocking code a lot more easily.
- Two new exception types, :exc:`Forbidden` and :exc:`NotFound` to denote permission errors or 404 errors.
- Added :meth:`Client.delete_invite` to revoke invites.
- Added support for sending voice. Check :class:`VoiceClient` for more details.
- Added :meth:`Client.wait_for_message` coroutine to aid with follow up commands.
- Added :data:`version_info` named tuple to check version info of the library.
- Login credentials are now cached to have a faster login experience. You can disable this by passing in ``cache_auth=False``
  when constructing a :class:`Client`.
- New utility function, :func:`discord.utils.get` to simplify retrieval of items based on attributes.
- All data classes now support ``!=``, ``==`` and ``str(obj)``.
- Added :meth:`Client.get_bans` to get banned members from a server.
- Added :meth:`Client.invites_from` to get currently active invites in a server.
- Added :attr:`Server.me` attribute to get the :class:`Member` version of :attr:`Client.user`.
- Most data classes now support a ``hash(obj)`` function to allow you to use them in ``set`` or ``dict`` classes or subclasses.
- Add :meth:`Message.clean_content` to get a text version of the content with the user and channel mentioned changed into their names.
- Added a way to remove the messages of the user that just got banned in :meth:`Client.ban`.
- Added :meth:`Client.wait_until_ready` to facilitate easy creation of tasks that require the client cache to be ready.
- Added :meth:`Client.wait_until_login` to facilitate easy creation of tasks that require the client to be logged in.
- Add :class:`discord.Game` to represent any game with custom text to send to :meth:`Client.change_status`.
- Add :attr:`Message.nonce` attribute.
- Add :meth:`Member.permissions_in` as another way of doing :meth:`Channel.permissions_for`.
- Add :meth:`Client.move_member` to move a member to another voice channel.
- You can now create a server via :meth:`Client.create_server`.
- Added :meth:`Client.edit_server` to edit existing servers.
- Added :meth:`Client.server_voice_state` to server mute or server deafen a member.
- If you are being rate limited, the library will now handle it for you.
- Add :func:`on_member_ban` and :func:`on_member_unban` events that trigger when a member is banned/unbanned.

Performance Improvements
~~~~~~~~~~~~~~~~~~~~~~~~~

- All data classes now use ``__slots__`` which greatly reduce the memory usage of things kept in cache.
- Due to the usage of ``asyncio``, the CPU usage of the library has gone down significantly.
- A lot of the internal cache lists were changed into dictionaries to change the ``O(n)`` lookup into ``O(1)``.
- Compressed READY is now on by default. This means if you're on a lot of servers (or maybe even a few) you would
  receive performance improvements by having to download and process less data.
- While minor, change regex from ``\d+`` to ``[0-9]+`` to avoid unnecessary unicode character lookups.

Bug Fixes
~~~~~~~~~~

- Fix bug where guilds being updated did not edit the items in cache.
- Fix bug where ``member.roles`` were empty upon joining instead of having the ``@everyone`` role.
- Fix bug where :meth:`Role.is_everyone` was not being set properly when the role was being edited.
- :meth:`Client.logs_from` now handles cases where limit > 100 to sidestep the discord API limitation.
- Fix bug where a role being deleted would trigger a ``ValueError``.
- Fix bug where :meth:`Permissions.kick_members` and :meth:`Permissions.ban_members` were flipped.
- Mentions are now triggered normally. This was changed due to the way discord handles it internally.
- Fix issue when a :class:`Message` would attempt to upgrade a :attr:`Message.server` when the channel is
  a :class:`Object`.
- Unavailable servers were not being added into cache, this has been corrected.
