No history information is provided for these components prior to the First Release. Note: The use of the dates 29, 30 and 31 of January 2002 is somewhat arbitrary. However, the chronological order of these dates is significant as it ensures that if Component History Table rows are applied in ReleaseVersion (i.e. date) order, the most recent change will be applied last.
