Signficant updates, changes or corrections to the StRD web pages are listed here in reverse chronological order.



Date Change
July 18, 2006 Added the privacy statement to the main page to comply with NIST standards for web pages.
November 20, 2003 Added the Markov Chain Monte Carlo datasets.
September 1, 2000 Updated the Related Resources page to point to recent articles about StRD and related work by researchers at NPL.
August 18, 1999

Changed the dataset names where necessary so that names would be no more than eight characters long. The names of data files were also changed to be consistent with the new dataset names. The names of the data files will be case sensitive if your operating system is case sensitive. The correspondence between the old and new names is listed below.
