Message.timestamp is replaced with Message.created_at. This commit
also affects how MESSAGE_UPDATE is handled by only assuming that two
keys are provided rather than overwriting data with missing keys.
If a command or a group raised a CommandError derived exception it
would be wrapped into CommandInvokeError. This fixes this case so it
raises the original exception instead.
This is to support people who want to clean up some external resource
that the extension is maintaining outside of a cog, where __unload
should be used instead.
The callable is the antipode of 'setup' and takes the same sole
parameter, the bot, after all commands, events, and cogs have been
unloaded.
Fixes#405.
Sometimes the bot would keep waiting for chunks that somehow finished
before getting to the `wait` call. This is more so a temporary fix
rather than a fully correct one.
Help formatter was not checking global bot-level checks, resulting in
showing commands a user did not have permission for with
show_check_failure disabled.
This is to allow people to set temporary local variables by injecting
them directly into the context via some decorator or some other
mechanism. Contexts are not kept alive long enough to warrant being
slotted.
Allow for easier use when trying to "reuse" the same discord.Embed
object by providing new methods such as Embed.clear_fields,
Embed.set_field_at, and allowing you to set things to Embed.Empty to
clear out an attribute.
For ease of use, things are automatically casted to ``str`` to prevent
the user from having HTTP 400 errors if they forgot to do so. The new
embed builder also supports "fluent-style" interface to allow you to
chain methods in a single line if necessary.
Certain parameters were removed since they were ignored by Discord
anyway such as `width` and `height` in Embed.set_image and
Embed.set_thumbnail.
