Ferret
Version v6.08 Release Notes
16-Nov-2007
Version 6.08 is required for users who wish to install the LAS (Live
Access Server) software, release Armstrong 1.1. It also has a few bug
fixes and additions for non-LAS users.
If you will be installing LAS Armstrong 1.1, please note that you need
to download and install the datasets that are included with this Ferret
release. The new datasets tar file includes a 4D ocean dataset used for
demonstrating new capabilities in LAS. It also includes
topography/bathemetry data on finer grids than previously included.
Follow the "Ferret datasets" link on the downloads page for
your operating system.
This Ferret release includes executables for Linux 32-bit and 64-bit;
Altix ia-64; and a statically-linked linux executable, for other Unix
systems. A Solaris 8 version is also included, however it is linked
with an older OPeNDAP library. Further Solaris builds are being built
and will be released shortly.
Enhancements and Bug fixes in Version 6.08
o A new set of symbols STAT* give access to the output of the STAT
command for use in scripts. The symbols contain results from the most
recent call to STAT.

o Two new symbols are defined after any plot of a 2D field.
AX_HORIZ and AZ_VERT each take on a value X, Y, Z, or T, representing
the direction of the axis that was plotted in the horizontal or
vertical direction. This information is used by LAS when zooming in or
out on a plot.
yes?
USE levitus_climatology
yes?
SHADE/Y=0 temp
yes?
SHOW SYMBOL ax*
AX_HORIZ
= "X"
AX_VERT

o In metafile batch mode (start ferret with "ferret -batch"),
previously all commands SET MODE metafile were ignored. Now, SET MODE
metafile newname.plt may be used to change the name of the metafile.
>
ferret -batch
yes?
shade/i=1:5/j=1:5 i+j ! This is in metafile.plt
yes?
set mode meta newname.plt
***
NOTE: in batch mode: SET MODE METAFILE only changes the name of the
metafile
yes?
! The following will be in newname.plt
yes?
plot/i=1:150 sin(i/20)
yes?
! Now newname.plt will be renamed to newname.plt.~1~
yes?
! and the next plot will be in newname.plt
yes?
plot/i=1:150 cos(i/20)
o A memory leak has been fixed - it was present in Ferret v6.0
through v6.07 and was seen when defining and redefining variables many
times.
o In Ferret v6.07, when drawing 2-D contour lines, all of the
contours for levels less than one are dark; Only the contour at 0
should be dark. This has been fixed.
o SHOW VARIABLE/XML, used by LAS, is fixed in order to write
correct XML output when the definition of the variable includes quotes.
This happens when there is a time interval given by dates in quotation
marks.
o Internal storage for some strings which contain URLs was too
short for the very-long F-TDS urls used by LAS Armstrong 1.1. This has
been fixed.
