15 Jul 2022

  • #196: In irc.bot, avoid hanging idle when the first connection attempt fails.


01 Jan 2022

  • SingleServerIRCBot no longer accepts reconnection_interval as a parameter.

  • Added server support for NOTICE commands.

  • Require Python 3.7 or later.


08 Sep 2020

  • #176: Fix issues with version number reporting. Restored version version number reporting in bot and client.


17 Jul 2020

  • irc.client no longer exposes a VERSION or VERSION_STRING. To get the version, call importlib.metadata.version('irc') directly.


19 Dec 2019

  • Require Python 3.6 or later.


29 Mar 2019

  • Rely on importlib_metadata for loading version from metadata. Removes implicit dependency on setuptools and pkg_resources.

  • #158: The AsyncIO server now accepts a connection factory to enable features like SSL and IPv6 support.

  • #155: SimpleIRCClient now has a dcc method for initiating and associating a DCCConnection object with the client. DCCConnection.listen now accepts a address parameter. Deprecated SimpleIRCClient.dcc_listen and SimpleIRCClient.dcc_connect in favor of the better separation of concerns. Clients should replace:

    client.dcc_connect(addr, port, type)


    client.dcc(type).connect(addr, port)


21 Oct 2018

  • Removed irc.buffer module, deprecated in 14.2.

  • #153: Drop support for Python 3.3 and 2.7.


01 Aug 2018

  • Long Term Service release for Python 2.7.

  • #149: AioConnection.connect moved to coroutine, added disconnect handling for AsyncIO.


20 May 2018

  • #140: Methods now use ‘connection’ and ‘event’ for parameter names.

  • #135 via #144: Added AsyncIO implementation.


06 Mar 2018

  • Package refresh and cleanup.


16 Dec 2017

  • #133: In irc.server, add support for ISON.


29 Oct 2017

  • #131: Add Connection.encode and Connection.transmit_encoding to enable encodings other than UTF-8 to be used when transmitting text.


23 Jun 2017

  • Removed deprecated execute_* methods on Connection and Reactor as introduced in 15.0.

  • Fixed link in README.


19 Apr 2017

  • New send_items method takes star args for simplicity in the syntax and usage.


19 Apr 2017

  • Introduce ServerConnection.send_items, consolidating common behavior across many methods previously calling send_raw.


20 Dec 2016


15 Nov 2016

  • #119: Handle broken pipe exception in IRCClient _send() (server.py).


28 Oct 2016

  • #116: Correct invocation of execute_every.


07 Oct 2016

  • #115: Fix AttributeError in execute_at in scheduling support.


28 Sep 2016

  • #113: Use preferred scheduler in the bot implementation.


12 Sep 2016

  • Deprecated calls to Connection.execute_* and Reactor.execute_*. Instead, call the equivalently-named methods on the reactor’s scheduler.


12 Sep 2016

  • The event scheduling functionality has been decoupled from the client.Reactor object. Now the reactor will construct a Scheduler from the scheduler_class property, which must be an instance of irc.schedule.IScheduler.

    The _on_schedule parameter is no longer accepted to the Reactor class. Implementations requiring a signal during scheduling should hook into the add method of the relevant scheduler class.

  • Moved the underlying scheduler implementation to tempora, allowing it to be re-used for other purposes.


11 Jun 2016

  • Issue #98: Add an ugly hack to force build_sphinx command to have the requisite libraries to build module documentation.


11 Jun 2016

  • Issue #97: Restore irc.buffer module for compatibility.

  • Issue #95: Update docs to remove missing or deprecated modules.

  • Issue #96: Declare Gitter support as a badge in the docs.


16 Apr 2016

  • Moved buffer module to jaraco.stream for use in other packages.


28 Feb 2016

  • SingleServerIRCBot now accepts a recon parameter implementing a ReconnectStrategy. The new default strategy is ExponentialBackoff, implementing an exponential backoff with jitter. The reconnection_interval parameter is now deprecated but retained for compatibility. To customize the minimum time before reconnect, create a custom ExponentialBackoff instance or create another ReconnectStrategy object and pass that as the recon parameter. The reconnection_interval parameter will be removed in future versions.

  • Issue #82: The ExponentialBackoff implementation now protects from multiple scheduled reconnects, avoiding the issue where reconnect attempts accumulate exponentially when the bot is immediately disconnected by the server.


15 Feb 2016

  • Dropped deprecated constructor connection.Factory.from_legacy_params. Use the natural constructor instead.

  • Issue #83: connection.Factory no longer attempts to bind before connect unless a bind address is specified.


31 Dec 2015

  • Now remove mode for owners, halfops, and admins when the user is removed from a channel.

  • Refactored the Channel class implementation for cleaner, less repetitive code.

  • Expanded tests coverage for Channel class.


31 Dec 2015

  • Issue #75: In irc.bot, add support for tracking admin status (mode ‘a’) in channels. Use channel.is_admin or channel.admins to identify admin users for a channel.

  • Removed deprecated irc.logging module.


20 Nov 2015

  • Moved hosting to github.


04 Oct 2015

  • Issue #67: Fix infinite recursion for irc.strings.IRCFoldedCase and irc.strings.lower.


23 Aug 2015

  • Issue #64: ISUPPORT PREFIX now retains the order of permissions for each prefix.


21 Aug 2015

  • Updated schedule module to properly support timezone aware times and use them by default. Clients that rely on the timezone naïve datetimes may restore the old behavior by overriding the schedule.now and schedule.from_timestamp functions like so:

    schedule.from_timestamp = datetime.datetime.fromtimestamp schedule.now = datetime.datetime.now

    Clients that were previously patching schedule.DelayedCommand.now will need to instead patch the aforementioned module-global methods. The classmethod technique was a poor interface for effectively controlling timezone awareness, so was likely unused. Please file a ticket with the project for support with your client as needed.


01 Jul 2015

  • Bump to jaraco.functools 1.5 to throttler failures in Python 2.


01 Jul 2015


25 Jun 2015

  • Pull Request #33: Fix apparent escaping issue with IRCv3 tags.


25 May 2015

  • Pull Request #32: Add numeric for WHOX reply.

  • Issue #62 and Pull Request #34: Add support for tags in message processing and Event class.


25 Apr 2015

  • Issue #60: Fix broken initialization of irc.server.IRCClient on Python 2.


10 Mar 2015

  • Issue #57: Better handling of Python 3 in testbot.py script.


28 Feb 2015

  • Remove changelog from package metadata.


25 Feb 2015

  • Remove dependency on jaraco.util. Instead depend on surgical packages.

  • Deprecated irc.logging in favor of jaraco.logging.

  • Dropped support for Python 3.2.


19 Feb 2015

  • Issue #55: Correct import error on Python 2.7.


18 Feb 2015

  • Decoding errors now log a warning giving a reference to the Decoding Input section of the readme.


15 Nov 2014

  • Renamed irc.client.Manifold to irc.client.Reactor. Reactor better reflects the implementation as a reactor pattern <. This name makes it’s function much more clear and inline with standard terminology.

  • Removed deprecated manifold and irclibobj properties from Connection. Use reactor instead.

  • Removed deprecated ircobj from SimpleIRCClient. Use reactor instead.


13 Nov 2014

  • Added ServerConnection.as_nick, a context manager to set a nick for the duration of the context.


27 Oct 2014

  • Dropped support for Python 2.6.

  • Dropped irc.client.LineBuffer and irc.client.DecodingBuffer (available in irc.client.buffer).

  • Renamed irc.client.IRC to irc.client.Manifold to provide a clearer name for that object. Clients supporting 8.6 and later can use the Manifold name. Latest clients must use the Manifold name.

  • Renamed irc.client.Connection.irclibobj property to manifold. The property is still exposed as irclibobj for compatibility but will be removed in a future version.

  • Removed unused irc.client.mask_matches function.

  • Removed unused irc.client.nick_characters.

  • Added extra numerics for ‘whoisaccount’ and ‘cannotknock’.


22 Oct 2014


26 Apr 2014

Documentation is now published at https://pythonhosted.org/irc.


25 Apr 2014

  • Issue #35: Removed the mutex during process_once.

  • Issue #37: Deprecated buffer.LineBuffer for Python 3.


24 Apr 2014

  • Issue #34: Introduced buffer.LenientDecodingLineBuffer for handling input in a more lenient way, preferring UTF-8 but falling back to latin-1 if the content cannot be decoded as UTF-8. To enable it by default for your application, set it as the default decoder:

    irc.client.ServerConnection.buffer_class = irc.buffer.LenientDecodingLineBuffer


21 Apr 2014

  • Introduced ‘Manifold’ as an alias for irc.client.IRC. This better name will replace the IRC name in a future version.

  • Introduced the ‘manifold’ property of SimpleIRCClient as an alias for ircobj.

  • Added ‘manifold_class’ property to the client.SimpleIRCClient to allow consumers to provide a customized Manifold.


17 Nov 2013

  • Issue #32: Add logging around large DCC messages to facilitate troubleshooting.

  • Issue #31: Fix error in connection wrapper for SSL example.


22 Sep 2013

  • Issue #28: Fix TypeError in version calculation in irc.bot CTCP version.


22 Sep 2013

  • Updated DCC send and receive scripts (Issue #27).


16 Aug 2013

  • Fix timestamp support in schedule.DelayedCommand construction.


10 Aug 2013

  • irc.client.NickMask is now a Unicode object on Python 2. Fixes issue reported in pull request #19.

  • Issue #24: Added DCCConnection.send_bytes for transmitting binary data. privmsg remains to support transmitting text.


19 Jul 2013

  • Code base now runs natively on Python 2 and Python 3, but requires six to be installed.

  • Issue #25: Rate-limiting has been updated to be finer grained (preventing bursts exceeding the limit following idle periods).


17 Jul 2013

  • Issue #22: Catch error in bot.py on NAMREPLY when nick is not in any visible channel.


04 Jul 2013

  • Fixed encoding errors in server on Python 3.


22 Apr 2013

  • Added a set_keepalive method to the ServerConnection. Sends a periodic PING message every indicated interval.


14 Apr 2013

  • Added support for throttling send_raw messages via the ServerConnection object. For example, on any connection object:


    That would set the rate limit to 30 Hz (30 per second). Thanks to Jason Kendall for the suggestion and bug fixes.


12 Apr 2013

  • Fix typo in client.NickMask.


04 Apr 2013

  • Fix typo in bot.py.


02 Apr 2013

  • Issue #15: Added client support for ISUPPORT directives on server connections. Now, each ServerConnection has a features attribute which reflects the features supported by the server. See the docs for irc.features for details about the implementation.


11 Feb 2013

  • Issue #14: Fix errors when handlers of the same priority are added under Python 3. This also fixes the unintended behavior of allowing handlers of the same priority to compare as unequal.


12 Jan 2013

This release brings several backward-incompatible changes to the scheduled commands.

  • Refactored implementation of schedule classes. No longer do they override the datetime constructor, but now only provide suitable classmethods for construction in various forms.

  • Removed backward-compatible references from irc.client.

  • Remove ‘arguments’ parameter from scheduled commands.

Clients that reference the schedule classes from irc.client or that construct them from the basic constructor will need to update to use the new class methods:

- DelayedCommand -> DelayedCommand.after
- PeriodicCommand -> PeriodicCommand.after

Arguments may no longer be passed to the ‘function’ callback, but one is encouraged instead to use functools.partial to attach parameters to the callback. For example:

DelayedCommand.after(3, func, ('a', 10))


func = functools.partial(func, 'a', 10)
DelayedCommand.after(3, func)

This mode puts less constraints on the both the handler and the caller. For example, a caller can now pass keyword arguments instead:

func = functools.partial(func, name='a', quantity=10)
DelayedCommand.after(3, func)

Readability, maintainability, and usability go up.


12 Jan 2013

  • Issue #13: TypeError on Python 3 when constructing PeriodicCommand (and thus execute_every).


05 Jan 2013

  • Fixed regression created in 7.0 where PeriodicCommandFixedDelay would only cause the first command to be scheduled, but not subsequent ones.


04 Jan 2013

  • Moved scheduled command classes to irc.schedule module. Kept references for backwards-compatibility.


01 Jan 2013

  • PeriodicCommand now raises a ValueError if it’s created with a negative or zero delay (meaning all subsequent commands are immediately due). This fixes #12.

  • Renamed the parameters to the IRC object. If you use a custom event loop and your code constructs the IRC object with keyword parameters, you will need to update your code to use the new names, so:

    IRC(fn_to_add_socket=adder, fn_to_remove_socket=remover, fn_to_add_timeout=timeout)


    IRC(on_connect=adder, on_disconnect=remover, on_schedule=timeout)

    If you don’t use a custom event loop or you pass the parameters positionally, no change is necessary.


29 Dec 2012

  • Fixed some unhandled exceptions in server client connections when the client would disconnect in response to messages sent after select was called.


28 Dec 2012

  • Moved LineBuffer and DecodingLineBuffer from client to buffer module. Backward-compatible references have been kept for now.

  • Removed daemon mode and log-to-file options for server.

  • Miscellaneous bugfixes in server.


27 Dec 2012

  • Fix error in 2to3 conversion on irc/server.py (issue #11).


25 Dec 2012

The IRC library is now licensed under the MIT license.

  • Added irc/server.py, based on hircd by Ferry Boender.

  • Added support for CAP command (pull request #10), thanks to Danneh Oaks.


15 Nov 2012

Another backward-incompatible change. In irc 5.0, many of the unnecessary getter functions have been removed and replaced with simple attributes. This change addresses issue #2. In particular:

  • Connection._get_socket() -> Connection.socket (including subclasses)

  • Event.eventtype() -> Event.type

  • Event.source() -> Event.source

  • Event.target() -> Event.target

  • Event.arguments() -> Event.arguments

The nm_to_* functions were removed. Instead, use the NickMask class attributes.

These deprecated function aliases were removed from irc.client:

- parse_nick_modes -> modes.parse_nick_modes
- parse_channel_modes -> modes.parse_channel_modes
- generated_events -> events.generated
- protocol_events -> events.protocol
- numeric_events -> events.numeric
- all_events -> events.all
- irc_lower -> strings.lower

Also, the parameter name when constructing an event was renamed from eventtype to simply type.


15 Nov 2012

  • Removed deprecated arguments to ServerConnection.connect. See notes on the 3.3 release on how to use the connect_factory parameter if your application requires ssl, ipv6, or other connection customization.


15 Nov 2012

  • Filter out disconnected sockets when processing input.


08 Nov 2012

  • Created two new exceptions in irc.client: MessageTooLong and InvalidCharacters.

  • Use explicit exceptions instead of ValueError when sending data.


06 Nov 2012

  • SingleServerIRCBot now accepts keyword arguments which are passed through to the ServerConnection.connect method. One can use this to use SSL for connections:

    factory = irc.connection.Factory(wrapper=ssl.wrap_socket)
    bot = irc.bot.SingleServerIRCBot(..., connect_factory = factory)


25 Oct 2012

  • Issue #6: Fix AttributeError when legacy parameters are passed to ServerConnection.connect.

  • Issue #7: Fix TypeError on iter(LineBuffer).


22 Oct 2012

3.4 never worked - the decoding customization feature was improperly implemented and never tested.

  • The ServerConnection now allows custom classes to be supplied to customize the decoding of incoming lines. For example, to disable the decoding of incoming lines, replace the buffer_class on the ServerConnection with a version that passes through the lines directly:

    irc.client.ServerConnection.buffer_class = irc.client.LineBuffer

    This fixes #5.


18 Oct 2012

Broken Release


17 Oct 2012

  • Added connection module with a Factory for creating socket connections.

  • Added connect_factory parameter to the ServerConnection.

It’s now possible to create connections with custom SSL parameters or other socket wrappers. For example, to create a connection with a custom SSL cert:

import ssl
import irc.client
import irc.connection
import functools

irc = irc.client.IRC()
server = irc.server()
wrapper = functools.partial(ssl.wrap_socket, ssl_cert=my_cert())
server.connect(connect_factory = irc.connection.Factory(wrapper=wrapper))

With this release, many of the parameters to ServerConnection.connect are now deprecated:

  • localaddress

  • localport

  • ssl

  • ipv6

Instead, one should pass the appropriate values to a connection.Factory instance and pass that factory to the .connect method. Backwards-compatibility will be maintained for these parameters until the release of irc 4.0.


14 Oct 2012

  • Restore Python 2.6 compatibility.


11 Oct 2012

  • Protect from UnicodeDecodeError when decoding data on the wire when data is not properly encoded in ASCII or UTF-8.


11 Oct 2012

  • Additional branch protected by mutex.


09 Oct 2012

  • Implemented thread safety via a reentrant lock guarding shared state in IRC objects.


07 Oct 2012

  • Fix some issues with bytes/unicode on Python 3


07 Oct 2012

  • Distribute using setuptools rather than paver.

  • Minor tweaks for Python 3 support. Now installs on Python 3.


29 Sep 2012

  • Added error checking when sending a message - for both message length and embedded carriage returns. Fixes #4.

  • Updated README.


05 Sep 2012

  • 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.


05 Sep 2012

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.


22 May 2012

  • 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


11 May 2012

  • Added irc.client.PeriodicCommandFixedDelay. Schedule this command to have a function executed at a specific time and then at periodic intervals thereafter.


10 May 2012

  • Removed irclib and ircbot legacy modules.


02 May 2012

  • Fix file saving using dccreceive.py on Windows. Fixes Sourceforge 6.

  • Created NickMask class from nm_to_* functions. Now if a source is a NickMask, one can access the .nick, .host, and .user attributes.

  • Use correct attribute for saved connect args. Fixes Sourceforge 16.


24 Apr 2012


24 Apr 2012


18 Apr 2012

  • Moved functionality from irclib module to irc.client module.

  • Moved functionality from ircbot module to irc.bot module.

  • Retained irclib and ircbot modules for backward-compatibility. These will be removed in 1.0.

  • Renamed project to simply ‘irc’.

To support the new module structure, simply replace references to the irclib module with irc.client and ircbot module with irc.bot. This project will support that interface through all versions of irc 1.x, so if you’ve made these changes, you can safely depend on irc >= 0.7, <2.0dev.


16 Apr 2012

  • Fixed failing test where DelayedCommands weren’t being sorted properly. DelayedCommand a now subclass of the DateTime object, where the command’s due time is the datetime. Fixed issue Sourceforge 15.


15 Apr 2012

  • Fixed incorrect usage of Connection.execute_delayed (again).


  • Minimum Python requirement is now Python 2.6. Python 2.3 and earlier should use 0.5.0 or earlier.

  • Removed incorrect usage of Connection.execute_delayed. Added Connection.execute_every. Fixed Sourceforge 8.

  • Use new-style classes.
