`aioxmpp`

... is a pure-python XMPP library using the asyncio standard library module from Python 3.4 (and available as a third-party module to Python 3.3).

Features

Native Stream Management (XEP-0198) support for robustness against transient network failures (such as switching between wireless and wired networks).
Powerful declarative-style definition of XEP-based and custom protocols. Most of the time, you will not get in contact with raw XML or character data, even when implementing a new protocol.
Secure by default: TLS is required by default, as well as certificate validation. Certificate or public key pinning can be used, if needed.
Support for RFC 6121 (Instant Messaging and Presence) roster and presence management, along with XEP-0045 (Multi-User Chats) for your human-to-human needs.
Support for XEP-0060 (Publish-Subscribe) and XEP-0050 (Ad-Hoc Commands) for your machine-to-machine needs.
Several other XEPs, such as XEP-0115 (including native support for the reading and writing the capsdb) and XEP-0131.
APIs suitable for both one-shot scripts and long-running multi-account clients.
Well-tested and modular codebase: aioxmpp is developed in test-driven style and in addition to that, many modules are automatedly tested against Prosody and ejabberd, two popular XMPP servers.

There is more and theres yet more to come! Check out the list of supported XEPs in the official documentation and open GitHub issues tagged as enhancement for things which are planned and read on below on how to contribute.
