Bug Fixes

• Fix issue with speaking state being cast to int when it was invalid.

v1.0.0

The changeset for this version are too big to be listed here, for more information please see :ref:`the migrating page <migrating_1_0>`.

v0.16.6

Bug Fixes

• Fix issue with :meth:`Client.create_server` that made it stop working.
• Fix main thread being blocked upon calling StreamPlayer.stop.

v0.16.0

New Features

• Add :attr:`Channel.overwrites` to get all the permission overwrites of a channel.
• Add :attr:`Server.features` to get information about partnered servers.

Bug Fixes

• Timeout when waiting for offline members while triggering :func:`on_ready`.

  • The fact that we did not timeout caused a gigantic memory leak in the library that caused thousands of duplicate :class:`Member` instances causing big memory spikes.

• Discard null sequences in the gateway.

  • The fact these were not discarded meant that :func:`on_ready` kept being called instead of :func:`on_resumed`. Since this has been corrected, in most cases :func:`on_ready` will be called once or twice with :func:`on_resumed` being called much more often.

v0.15.1

• Fix crash on duplicate or out of order reactions.

v0.15.0

• Add support for MESSAGE_REACTION_REMOVE_ALL event, under :func:`on_reaction_clear`.

• Add :meth:`Permissions.update` and :meth:`PermissionOverwrite.update` for bulk permission updates.

  • This allows you to use e.g. p.update(read_messages=True, send_messages=False) in a single line.

• Add :meth:`PermissionOverwrite.is_empty` to check if the overwrite is empty (i.e. has no overwrites set explicitly as true or false).

For the command extension, the following changed:

• Context is no longer slotted to facilitate setting dynamic attributes.

v0.14.3

Bug Fixes

• Fix crash when dealing with MESSAGE_REACTION_REMOVE
• Fix incorrect buckets for reactions.

v0.14.2

New Features

• :meth:`Client.wait_for_reaction` now returns a namedtuple with reaction and user attributes.

  • This is for better support in the case that None is returned since tuple unpacking can lead to issues.

Bug Fixes

• Fix bug that disallowed None to be passed for emoji parameter in :meth:`Client.wait_for_reaction`.

v0.14.1

  • This applies for :class:`PermissionOverwrite` as well.

• Add new statuses for :class:`Status`.

  • :attr:`Status.dnd` (aliased with :attr:`Status.do_not_disturb`) for Do Not Disturb.
  • :attr:`Status.invisible` for setting your status to invisible (please see the docs for a caveat).

• Deprecate :meth:`Client.change_status`

  • Use :meth:`Client.change_presence` instead for better more up to date functionality.

• Add :attr:`Server.role_hierarchy` to get the server's role hierarchy.

• Add :attr:`Member.server_permissions` to get a member's server permissions without their channel specific overwrites.

• Add :meth:`Client.get_user_info` to retrieve a user's info from their ID.

• Add a new Player property, Player.error to fetch the error that stopped the player.

  • To help with this change, a player's after function can now take a single parameter denoting the current player.

• Add support for server verification levels.

• Command names are no longer forced to be lower().
• Fix a bug where Member and User converters failed to work in private message contexts.
• HelpFormatter now ignores hidden commands when deciding the maximum width.

v0.10.0

For breaking changes, see :ref:`migrating-to-async`. The breaking changes listed there will not be enumerated below. Since this version is rather a big departure from v0.9.2, this change log will be non-exhaustive.

New Features

• The library is now fully asyncio compatible, allowing you to write non-blocking code a lot more easily.
• The library now fully handles 429s and unconditionally retries on 502s.
• A new command extension module was added but is currently undocumented. Figuring it out is left as an exercise to the reader.
• 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 !=, ==, hash(obj) 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.
