This note is particularly intended for echelle observers.  Others may
not be affected.

The official version of Remark is still 2.62, as announced every time
you open a Remark connection.  A more recent version of Remark, 2.75,
is available, and includes several tempting features for echelle
observers such as autoguiding.  However, we have discovered some bugs
with this version and it will NOT be made official until those bugs
have been fixed in a later version (which may be more than a month
from now, due to unavailability of the programmer).  Any echelle
observer who chooses to run version 2.75 rather than 2.62 should be
aware that time lost due to bugs in the newer version will not be
accounted to equipment failure; it is the observer's choice whether or
not to take this risk.  Version 2.62 is not entirely innocent of
problems either; it's simply that the problems with that version are
better known and so more easily avoided.  Those observers who have
loaded version 2.75 onto your observing Macs, please ensure that 2.62
is also available for anyone who doesn't wish to try the experimental
version.

I'd also like to note that, in addition to the bugs, the autoguiding
algorithms are not fully tested yet.  I would welcome comments from
any observer who does choose to try out the autoguiding as to whether
it is really any better than guiding by hand.  If you're going to try
the newer Remark version anyway, please help us to find and work out
its shortcomings.

For instruments other than the echelle, there is no difference between
version 2.62 and 2.75.

				Russet.
