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.
We just released (a)Smack 4.0.7. This is a bugfix only release.
It was found that the passed "hostname" argument to the configured HostnameVerifier in Smack 4.0 was server controllable, which could allow a malicious attacker to circumvention hostname verification. Hostname verification is disabled by default in Smack 4.0, but enabled by default in Smack 4.1. The faulty code was long ago removed in the Smack 4.1 branch, so most Smack 4.1 (pre-)releases are not affected.
As a reminder: The second release candidate of Smack 4.1 is available. Consider updating when possible, but please refer to the Smack 4.1 Readme and Upgrade Guide · igniterealtime/Smack Wiki · GitHub first.
The Ignite Realtime community is happy to announce the first release candidate of the upcoming Smack version 4.1. Smack is an open source XMPP client library written in Java with multi-runtime support. It can be used with Java SE and Android runtimes. If you haven't done already now is the ideal time to grab Smack 4.1.0-rc1 and try it out. A '4.1' branch has been created, that will track the further development of Smack 4.1. The API of Smack 4.1 is now officially stable and will not change in an incompatible way between further 4.1 releases.
I'd like to thank everyone at FOSDEM 2015 and XMPP Summit for such a nice time and interesting talks. I sure haven't talk to all people at the XMPP Summit, but hope that we'll meet again soon. You can find my slides of my lightning talk "XMPP and Android" at http://geekplace.eu/files/xmpp_and_android.pdf
While travelling home from Brussels in the ICE, I was able to prepare and upload beta2 of Smack 4.1. Please update your build setups and report any issues in the forum.
The Ignite Realtime community is happy to announce the first beta version of the upcoming Smack version 4.1. Smack is an open source XMPP client library written in Java with multi-runtime support. It can be used with Java SE and Android runtimes. If you haven't done already now is the ideal time to grab Smack 4.1.0-beta1 and try it out. Compared to the alpha versions of 4.1 the API is considered stable and API changes are unlikely to happen.
Everyone is invited to test beta1 in his projects. The community forum awaits your feedback and bug reports. Although the beta version has proven reliable so far, please only use it productive after intensive testing.
An incomplete list of API changes can be found in the Smack 4.1 Readme and Upgrade Guide. Please consult the Readme before using Smack 4.1.
After months of hard work it's at the time to release the first alpha version of Smack 4.1, the open source Java XMPP client library, for testing purposes.
Smack 4.1 marks a milestone in the development history of Smack, as it's the first version that runs native on Android. This means that aSmack is no longer required and will be phased out in the future. Future aSmack releases will be solely form the stable 4.0 branch.
Together with support for Android, Smack 4.1 also adds support for XEP-198 "Stream Management" in smack-tcp. XMPP connections with enabled Stream Management provide acknowledgments of sent stanzas (and acknowledges received stanzas to the server) and allow transparent stream resumption in case of a network outage (for example because of a WiFi ↔ GSM switch on Android).
Smack 4.1.0-alpha1 is now available from Maven Central and we would welcome interested and adventurous users to try this early alpha release and provide feedback. For more information about using Smack 4.1 and how to include it in your Android project, consult the "Smack 4.1 Readme and Upgrade Guide".
