WHATSNEW.DOC September 1991
This lists the user visible changes to ARJ from previous versions.
ARJ 2.21
** IMPORTANT NEWS ****************************************************
ARJ now has built-in MS-DOS 3.x international language support.
On a very small number of large files, the use of the option
-jh65535 has resulted in system hangs and file CRC errors. This
only occurs with the number 65535. If you use this option
without the -jt option, you should verify your archived files.
I extend my deepest apologies to everyone so inconvenienced.
This is fixed in ARJ 2.21.
**********************************************************************

letters is properly handled (such as the "u" with umlaut) on
the command line and with the ARJ "w" command.

Speeded up ARJ "w" command.

Slightly revised LICENSE.DOC and ORDERFRM.DOC.
Significantly speeded up self-extraction from diskettes.
Fixed ARJSFXJR (-je1) to send its output to standard output.
