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

    ARJ 2.21 does NOT correctly garble (-g option) stored (-m0)
    files larger than 32767 bytes.    ARJed GIFs and archives may have
    this problem, since ARJ reverts to storing when unable to
    compress the file.  Archived files with this problem will
    test/extract with a CRC error.    ARJ 2.21a has an option "-h+" to
    correctly extract such files.

     **********************************************************************

     Fixed garble bug with stored files larger than 32767 bytes.
     Fixed slight inefficiency when extracting stored files.


     ARJ 2.21

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

    On a very small number of large files, the use of the option
    -jh65535 has resulted in system hangs and file CRC errors.  This
    occurs with the number 65535 and 65534.  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.

     **********************************************************************
