Smack is an Open Source XMPP (Jabber) client library for instant messaging and presence. A pure Java library, it can be embedded into your applications to create anything from a full XMPP client to simple XMPP integrations such as sending notification messages and presence-enabling devices.
A critical security vulnerability has been found in Smack. Please upgrade immediately to Smack 4.1.9. Like all Smack releases with the same major and minor version numbers, 4.1.9 is a drop in replacement for all Smack 4.1 releases. Smack 4.1.9 is available on Maven Central.
The Ignite Realtime community would like to thank Sylvain Sarméjeanne for discovering and reporting the vulnerability to firstname.lastname@example.org.
I've just uploaded Smack 4.1.8 and 4.2.0-beta2 to Maven Central.
Smack 4.1.8 fixes a few minor issues and is expected to be the last release of the 4.1 branch. As always, Smack releases with the same major and minor version numbers are drop in replacements. Ideally you just need to change a single variable somewhere in your build system.
Smack 4.2.0-beta2 is the latest beta of Smack's current development branch. Notable additions include support for XEP-0313: Message Archive Management (MAM) and the IoT XEP series.
Starting with b91978dcc4ae partial support for the IoT XEPs was added to Smack. The XEPs consists, amongst other XEPs, of
The XEPs are in experimental state, which means changes to them are possible.
Smack does currently only support a partial set of the mechanisms specified, especially when it comes to Data and Control. For example only boolean and integer values can be read and written But support for more data types can be easily added.
The development of the API was sponsored by Clayster.
Clayster creates technology to secure trust in the transactions between physical and digital entities, and strives to be that generic foundation for your physical assets digital life.
Clayster has an IoT discovery and provisioning platform supporting XEP-0347 and XEP-0324. The platform is available for those who are interested to explore XMPP and IoT further. If you don't want to run your own infrastructure, Clayster is able to provide an XMPP Server and the discovery/provisioning platform for you.

Two new releases of Smack have just been pushed to Maven Central.
Smack 4.1.7 fixes a few bugs. One noteworthy bug is that on certain platforms Smack's setEnabledSSL(Protocols|Ciphers) had no effect. More information about the fixed bugs can be found in the Release Notes.
The careful reader may noticed that this is the first beta release of Smack 4.2. Which means that Smack 4.2 just entered the beta phase. My rough timeplan is to release Smack 4.2 in 6 months: starting with 3 months long beta period now, followed by 3 months of release candidates. But as all schedules in the software industry, take it with a grain of salt.
I've just released and uploaded Smack 4.1.6 and 4.2.0-alpha3 to Maven Central.
Smack 4.1.6 contains a few important bug fixes for Smack's stable branch: 4.1. The changelog can be found here: Smack Changelog
The third alpha version of Smack's upcoming development branch contains a ton of fixes and new features. Adventurous users are encouraged to explore the API improvements. But, as the version name suggests, don't use an alpha version for production deployments. A provisional and incomplete list of Smack 4.2's highlights can be found at Smack 4.2 Readme and Upgrade Guide · igniterealtime/Smack Wiki · GitHub
