Implemented XEP-0054 and XEP-0153 (see Net::XMPP2::Ext::VCard), on top of that a serious bug in split_jid in Net::XMPP2::Util was fixed and a connect_timeout argument can be set now for Net::XMPP2::Connection.
Aside from that a few changes here and there, but nothing serious, see the Changes file.
Mainly a maintenance release. The init method for the connection classes have been made implicit on connect. So you should not call it yourself anymore.
Aside from that there were some documentation fixes in Net::XMPP2::Client.
Other additions were the xmpp_datetime_as_timestamp in Net::XMPP2::Util and the nick collision callback in Net::XMPP2::Ext::MUC, to change the nick when the nick has already been taken when joining a room.
The tests have been tweaked a bit and a Pod::Coverage test has been added.
Fixed some bugs and implemented an old/ancient authentication method used by some very old (jabberd 1.4.2) servers. Also implemented a chat session tracking mechanism to help the users of Net::XMPP2::Client to get their message to the right resource. (See also the method send_tracked_message of Net::XMPP2::IM::Account).

Lots of bugfixes and minor changes you might want to read about in the Changes file. Added some examples which might be useful.
Introduced a character filter on the low XML writer level which will filter out not allowed XML characters to prevent unexpected disconnects. Arguably this is the programmers fault but I hope noone is confuses if this module tries everything to be as reliable as possible.
Also fixed some bugs.
For further details look in the Changes file.
The event API has been changed a bit, its possible to intercept events now, see Net::XMPP2::Event.
Implemented the old legacy XEP-0078 (IQ authentication), see also Net::XMPP2::Ext for some notes about it.
Some bugs with JID preps have been fixed and some functions for JID handling have been added to Net::XMPP2::Util.
Implemented following new XEPs:
- XEP-0082 - XMPP Date and Time Profiles - XEP-0091 - Delayed Delivery (legacy) - XEP-0092 - Software Version - XEP-0203 - Delayed Delivery (new)
For further information about them see Net::XMPP2::Ext.
I also started an implementation of XEP-0045 (Multi User Chats), please consult the test t/z_05_muc.t and the API at Net::XMPP2::Ext::MUC for the already working features. (Very basic MUCing should work, but there are lots of edges still with error reporting and all the other nice features).
Also enhanced the message API a bit see Net::XMPP2::IM::Message and the methods of other classes that generate messages (eg. like make_message).
There has been a considerable efford in test writing. Added instructions about the test suite below in section TEST SUITE.
And another API change: reply_iq_result and reply_iq_error now attach a from attribute themselves (see Net::XMPP2::Connection).
The tests require network access to a jabber server and wont run unless you set the right environment variable. If you want to run these tests yourself you might want to take a look at Net::XMPP2::TestClient.
While implementing in band registration I implemented XEP-0066: Out of Band Data. You can now receive and send URLs from and to others. See also Net::XMPP2::Ext::OOB.
I also fixed some bugs in Net::XMPP2::Ext::Disco.
There are still lots of items on the TODO list (see also the TODO file in the distribution of Net::XMPP2).
If you are a developer and want to test either a server or maybe just whether this module passes some basic tests you might want to run the developer test suite.
This test suite is not enabled by default because it requires some human interaction to set it up, please see Net::XMPP2::TestClient for hints about the setup procedure for the test suite.
I wrote the test suite mostly because I wanted to make sure I didnt break something essential before a release. The tests dont cover everything and I dont plan to write a test for every single function in the API, that would slow down development considerably for me. But I hope that some grave show stopper bugs in releases are prevented with this test suite.
The tests are also useful if you want to test a server implementation. But there are maybe of course conformance issues with Net::XMPP2 itself, so if you find something where Net::XMPP2 doesnt conform to the XMPP RFCs or XEPs consult the BUGS section below.
If you find a server that doesnt handle something correctly but you need to interact with it you are free to implement workarounds and send me a patch, or even ask me whether I might want to look into the issue (I cant gurantee anything here, but I want this module to be as interoperable as possible. But if the implementation of a workaround for some non-conformant software will complicate the code too much Im probably not going to implement it.).
The main outstanding feature of this module in comparison to the other XMPP (aka Jabber) modules out there is the support for AnyEvent. AnyEvent permits you to use this module together with other I/O event based programs and libraries (ie. Gtk2 or Event).
The other modules could often only be integrated in those applications or libraries by using threads. I decided to write this module because I think CPAN lacks an event based XMPP module. Threads are unfortunately not an alternative in Perl at the moment due the limited threading functionality they provide and the global speed hit. I also think that a simple event based I/O framework might be a bit easier to handle than threads.
Another thing was that I didnt like the APIs of the other modules. In Net::XMPP2 I try to provide low level modules for speaking XMPP as defined in RFC 3920 and RFC 3921 (see also Net::XMPP2::Connection and Net::XMPP2::IM::Connection). But I also try to provide a high level API for easier usage for instant messaging tasks and clients (eg. Net::XMPP2::Client).
This module also supports TLS, as the specification of XMPP requires an implementation to support TLS.
Maybe there are still some bugs in the handling of TLS in Net::XMPP2::Connection. So keep an eye on TLS with this module. If you encounter any problems it would be very helpful if you could debug them or at least send me a detailed report on how to reproduce the problem.
(As I use this module myself I dont expect TLS to be completly broken, but it might break under different circumstances than I have here. Those circumstances might be a different load of data pumped through the TLS connection.)
I mainly expect problems where available data isnt properly read from the socket or written to it. You might want to take a look at the debug_send and debug_recv events in Net::XMPP2::Connection.
See Net::XMPP2::Ext for a list.
Following examples are included in this distribution:
For others, which the author might forgot or didnt want to list here see the samples/ directory.
<B>samples/simple_example_1B> This example script just connects to a server and sends a message and also displays incoming messages on stdout. <B>samples/devcl/devclB> This is a more advanced example. It requires you to have Gtk2 installed. Its mostly used by the author to implement proof-of-concepts. Currently you start the client like this:
../Net-XMPP2/samples/devcl/# perl ./devcl <jid> <password>
The clients main window displays a protocol dump and there is currently a service discovery browser implemented.
This might be a valuable source if you look for more real-world applications of Net::XMPP2.
<B>samples/conference_listerB> See below. <B>samples/room_listerB> See below. <B>samples/room_lister_statB> These three scripts implements a global room scan. conference_lister takes a list of servers (the file is called servers.xml which has the same format as the xml file at <http://www.jabber.org/servers.xml>). It then scans all servers for chat room services and lists them into a file conferences.stor, which is a Storable dump.
room_lister then reads that file and queries all services for rooms, and then all rooms for their occupants. The output file is room_data.stor, also a Storable dump, which in turn can be read with room_lister_stat, which transform the data structures into something human readable.
These scripts are a bit hacky and quite complicated, but maybe its of any value for someone. You might note EVQ.pm in samples which is a module that handles request-throttling (You dont want to flood the server and risk getting the admins attention :).
<B>samples/simple_componentB> This is a (basic) skeleton for a jabber component. <B>samples/simple_oob_retrieverB> This is a simple out of band file transfer receiver bot. It uses curl to fetch the files and also has the sample functionality of sending a file url for someone who sends the bot a send <filename> message. <B>samples/simple_register_exampleB> This is a example script which allows you to register, unregister and change your password for accounts. Execute it without arguments for more details. <B>samples/disco_infoB> This is a small example tool that allows you to fetch the software version, disco info and disco items information about a JID. <B>samples/talkbotB> This is a simple bot that will read lines from a file and recite them when you send it a message. It will also automatically allow you to subscribe to it. Start it without commandline arguments to be informed about the usage. <B>samples/retrieve_rosterB> This is a simple example script that will retrieve the roster for an account and print it to stdout. You start it like this:
samples/# ./retrieve_roster <jid> <password>
<B>samples/display_avatarB> This is just a small example which should display the avatar of the account you connect to. It can be used like this:
samples/# ./display_avatar <jid> <password>
More examples will be included in later releases, please feel free to ask the AUTHOR if you have any questions about the API. There is also an IRC channel, see SUPPORT.

Thanks to the XSF for the development of an open instant messaging protocol (even though it uses XML).
And thanks to all people who had to listen to my desperate curses about the brokenness/braindeadness of XMPP. Without you I wouldve never brought this module to a usable state.
