The upgrades form part of what the company calls a "feature release", as distinguished from a platform release, which sees more substantial changes to the architecture of the software. Citrix is using the designations to ease user anxiety over recurring software upgrades in what it calls a "modular software delivery approach".
Metaframe XP for Windows, Metaframe for Unix, Citrix Nfuse and Citrix Extranet all have new features.
Feature Release 1 for Metaframe XP includes Secure Sockets Layer (SSL) 128-bit encryption for users passing content through the company firewall.
Connection Control ensures that application licences are not exceeded by limiting the number of users operating specific software at any given time.
As the name implies, CPU Prioritisation ensures that processing power is dedicated to mission-critical applications.
Other features in the release include a universal printer driver and support for Computer Associates' Unicenter and Novell Directory Services.
Metaframe for Unix includes support for up to 16 million colours for users connecting to high-resolution devices - such as Cad applications in engineering - from any location. Client drive mapping has been added, which allows files stored on Unix servers to be moved to client devices more easily.
The company's virtual private network software, Extranet 2.5, has had SSL encryption added.
Nfuse 1.6, Citrix's portal software, will be given away free to customers. It allows a single view to be built from numerous applications on local and wide area networks and now supports the Metaframe Unix and Windows versions.
Subscription Advantage, an annual fee system, entitles users to feature and platform releases free of charge.
