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.
TLS and SASL support have been tested extensively with many popular client. The main reason we named this release an alpha version and not a beta version is that we wanted to make these new features available even though we will continue adding new features for the final version. Please post any feedback in the forum.
