     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.

     Fixed ARJ to abort on reaching end of file early when using STDIN.

     ARJ 2.10

     ** IMPORTANT NEWS ****************************************************

    ARJ utility developers should refer to UNARJ.DOC in UNARJ.ARJ
    concerning a bug in extended header processing in UNARJ.C and an
    ambiguous source statement in DECODE.C.

    because of an undesirable interaction with TSR DIET 1.02b.  You
    should redo any ARJ SFX type archives with ARJ 2.20.  Here is a
    fast way to do it without recompressing:

    ARJ j newsfx oldsfx.exe -je
