The alpha 1 release of Jive Messenger 2.3.0 is url=http://www.jivesoftware.org/downloads.jspnow available[/url]. Although the changelog is quite small, this release represents an important step forward for the project with TLS (c2s), SASL (c2s) and PAM authentication support.
This is an alpha release not because the code is in alpha state but because we will continue adding new features for the final version. Please post beta feedback in the support forum.
Enjoy!
