Irc

=====

* Fix some issues with bytes/unicode on Python 3

===

* Distribute using setuptools rather than paver.
* Minor tweaks for Python 3 support. Now installs on Python 3.

=====

* Added error checking when sending a message - for both message length and
embedded carriage returns. Fixes 4.
* Updated README.

===

* Improved Unicode support. Fixes failing tests and errors lowering Unicode
channel names.
* Sourceforge 18 - The ServerConnection and DCCConnection now encode any
strings as UTF-8 before transmitting.
* Sourceforge 17 - Updated strings.FoldedCase to support comparison against
objects of other types.
* Shutdown the sockets before closing.

Applications that are currently encoding unicode as UTF-8 before passing the
strings to `ServerConnection.send_raw` need to be updated to send Unicode
or ASCII.

=====

This release officially deprecates 2.0.1-2.0.3 in favor of 3.0.

* Re-release of irc 2.0 (without the changes from 2.0.1-2.0.3) for
correct compatibility indication.

===

* DelayedCommands now use the local time for calculating 'at' and 'due'
times. This will be more friendly for simple servers. Servers that expect
UTC times should either run in UTC or override DelayedCommand.now to
return an appropriate time object for 'now'. For example::

def startup_bot():
irc.client.DelayedCommand.now = irc.client.DelayedCommand.utcnow
