Sametime 12Beta Sametime 11 Sametime 9
HCL Sametime 12 2026 server & desktop plug-in previews Beta Preview, not a supported production release. These beta packages are intended for isolated testing, not mission-critical deployment. The desktop plug-in supports HCL Sametime 12 and has been verified working in internal testing; its build target remains HCL Sametime Connect 11.5 for Windows (32-bit). The server JAR requires an existing configured server runtime; see its release notes before replacing a file.
Installing the desktop plug-in upgrades the existing ITS plug-in; the old and new versions cannot run side by side in one client. Keep your previous packages and back up your settings.
