Smack 4.2 is the current stable release of Smack. The full list of fixed issue and improvements can be found in the JIRA release notes for Smack 4.2.

Experimental support for DNSSEC was added. For more information, have a look at the documentation.

Methods invoking network operations and awaiting responses are now interruptible. This means you can interrupt the thread performing them in case they are take too long to complete.

JXMPP's JID types provide an powerful yet simply to use abstraction over an XMPP address (also called "JID"). This helps to minimize problems caused by using the wrong JID type or by the normalization applied to JIDs. To create a JID from a CharSequence (this includes String) simply use JidCreate.from(charSequence).

The MUC API was improved allowing easy creation of rooms and joining them.

Smack now supports SASL authzid.

Warning: This list may not be complete

In previous versions of Smack, ConnectionConfiguration.setHost(String) could be used to set the XMPP service's host IP address. This is no longer possible due to the added DNSSEC support. You have to use the new connection configuration ConnectionConfiguration.setHostAddress(InetAddress) instead.

Use ConnectionConfiguration.performSaslAnonymousAuthentication() instead. Then simply call the zero argument variant of login().

• Rewrote the PEP API to use the existing PubSub API
• Renamed processPacket(Stanza) to processStanza(Stanza)
• Renamed PacketCollector to StanzaCollector

Smack 4.2 provides two artifacts as entry points that you can refer to when including Smack in your project: smack-java7 and smack-android. A typical Smack setup may also want to additional declare dependencies on smack-tcp, smack-extensions and smack-experimental

getMavenArtifactsNg.py -f artifacts.csv -p <projectdir>

to let the script download and install the artifacts into your Android Ant project.
