Here is a summary of the changes since the last update in October:

edu/wisc/ssec/mcidas/AreaDirectoryList.java  revision 1.12  date:
2008/11/17 18:05:00   author: tomw
 Remove check of first int coming back from an ADDE request -- turns out
 that this can be any random number, and cannot be used as a "sanity
check" word....inspite of the doc.

2008/11/15 16:39:09   author: donm

 the default like it should

 fix for merge1DSet

edu/wisc/ssec/mcidas/AreaFile.java  revision 1.35  date: 2008/11/11
17:58:50   author: tomw
 Fix long-standing issue with ADDE servers sending un-signed 1- and 2-byte
 data values.....it took until now, when someone started looking at fires,
 to uncover this issue...I guess temperatures of -413K were just too cold...

author: donm
 play God and convert mass/area to length
