Just got this on the digest; Communigate Pro V5.2.2 has been
released. For the first time there is a 5.2 build for VMS, but the
letter only showed Itanium, not Alpha. They did release this version
for Tru-64 on Alpha though.

I haven't written to ask about the Alpha build yet, but the available
OpenVMS alpha kit is still at V5.1.4. Stalker has not responded to
previous questions about newer VMS builds.

OpenVMS - Itanium

So if you're on an itanic, this is good news.
