Microsoft is continuing to stuff more features into version 5.0 of Windows NT, making further delays to the operating system likely.
Microsoft had said in July (see Newswire 2 July) that beta 2 of the product would be "feature complete", but now plans to include an updated version of the COM+ software framework, which is due to ship in September, and the Valence Research clustering technology that it acquired last week.
The Convoy Cluster Software for NT provides load balancing over a TCP/IP network and will be incorporated into the Enterprise Edition of NT 5.0. It will also ship as an add-on pack to NT 4.0.
As a result, the latest feature complete beta falls somewhere between 2 and 3 and will be made available at the Professional Developers' Conference in Denver in October, according to US reports.
It will also include changes to the kernel of the operating system with alterations to quantum controls and table entries, which determine how long a thread should take to access the CPU before the scheduler allows another thread to access the system.
This provides greater control over thread execution and system resources, but means that users need to rewrite their applications to take advantage of the new features.
