Yet another new binary release, based on revision 31, is now
available. New in this build are some bug fixes, and a working
implementation of the three-column hex view. This part is neat; if you
select a range in the hex view, the corresponding selection is made in
the "visible" character view. Next, if you select parts of a packet in
the detail tree view (the middle pane) the corresponding parts in the
hex and visible character views; copy and copy-as-hex will copy the
selected parts.

Happy hacking.
