In order to allow more specific listings of changes within MAST,
the user may now select both the mission and time period for
which to view changes. Once these options are choosen, clicking
GO will generate and display the requested list of changes.
By default, the What's New link from the top MAST page
will display news entries for all MAST missions which occurred
in the past 6 months.
The What's New links available from the individual
mission pages access the same master list of changes, but only
news items for that particular mission are displayed.
This entry specifies the mission for which to view changes.
Besides the current MAST-supported missions (i.e.,
BEFS, COPERNICUS, DSS, EUVE, FIRST, FUSE, HST, HUT, IUE, IMAPS,
ROSAT, UIT, and WUPPE), one may also select ALL (the default selection)
or OTHER, which describes general changes not related to a particular
mission (note ALL includes OTHER).
The period of time over which to view MAST-related changes, starting
from the day the list is generated. The current options include:
last month, last 3 months (the default), last 6 months, last year, and all.
