The code hasn't changed much. If your ead the docs carefully the
changes should be obvious.
Please find attached a patch (against 1.38.3-22Dec05) which does a
bit more: I wanted to be able to have a direct mapping between a
"magazine name" and volume names. For example, when I insert the
magazine labeled "X" I run the command
/etc/bacula/set_maginfo X
and in bacula I can just do a "update slots". The mapping between
magazine name, slot number and volume name is done using a simple
text file "/etc/bacula/Magazines.conf". [There is also a small script
"get_maginfo" to display the name of the current magazine.]

While we are at it: on another box where we have a drive with a
barcode reader I got sick of the cryptic barcode ID's. The following
patch can be used to use text file "/etc/bacula/Barcodes.conf" to map
a barcode ID of "AIH917" into the corresponding volume name "K-C-4".
