OpenVMS remains the operating environment of choice for enterprises that require mission critical business continuity, scalability, high availability, and uncompromising security.

The current release of OpenVMS, version 8.4-2L1 "Hudson Release," supports the latest OpenSSL standards and continues a long history of unmatched, granular security (see security details below)

All releases of VSI's OpenVMS are binary compatible with prior OpenVMS Itanium versions, allowing customers to upgrade without having to recompile or relink their applications, providing best in class total cost of ownership benefits.

See detailed QuickSpecs of VSI's versions of OpenVMS.

What's New

This new release is identical to the last Maynard release of OpenVMS, except for one major difference: all components of OpenVMS that rely on OpenSSL have been upgraded to use the latest VSI SSL release, VSI SSL1 V1.0, which is an implementation of the OpenSSL V1.0.2 standard. OpenSSL is used by many operating system functions, networking products, OpenVMS layered products, and open source applications.

The prevalence of OpenSSL usage required that we release OpenVMS V8.4-2L1 in a default installation, where OpenSSL V1.0.2 is released in coordination with all software components that use it. This delivery strategy simplifies release packaging and testing—rather than burdening users with the potential complications of multiple patch kit updates.

These SSL-related software components are updated in VSI OpenVMS V8.4-2L1:

   • OpenVMS V8.4-2L1 with updates to ENCRYPT, ACME, ACMELDAP

   • VSI SSL1 V1.0


   • VMS Notary

   • CSWS (Apache)

   • Enterprise Directory (X.500)

   • WBEM

VMS Software is committed to continuing improvements to security. This release is a major step in that direction. SSL is a critical tool that processes or applications use to encrypt files and communications. The prior version of SSL used by OpenVMS was based on OpenSSL 0.9.8, an outdated standard that is rejected by a growing number of hosts, applications, and other operating systems. This update brings OpenVMS into compliance with the latest OpenSSL standard.

One more thing...

VSI is pleased to provide a new VSI-supported version of Secure Web Server (SWS) for OpenVMS based on Apache HTTP Server Version 2.4-12 from the Apache Software Foundation.

SWS V2.4-3 represents a significant update from previous versions, providing many new features and numerous enhancements including reduced memory utilization and more flexible configuration. New loadable modules provide new and enhanced functionality in areas such as session management, request filtering, rate limiting, and proxying. SWS V2.4-3 also provides improved support for the development of custom loadable modules. See details in the V8.4-2L1 Release Notes.
