Several new features have been added to PKZIP/PKUNZIP/PKSFX
version 4.1V.  Read the file ADDENDUM.DOC for a complete
description of these changes and enhancements.  Highlights
of PKZIP/PKUNZIP/PKSFX etc. version 4.1V include:

- PKZIP 4.1V's X-XTRA is up to 11X faster and 3X more compression,
  particularly on large spreadsheet, database type files, and multiple
  small data files such as a 1k to 2k files, where PKZIP 2.04g would run
  relatively slowly and PKZIP 3.05 relatively faster but with possible data
  corruption.  Most 'typical' types of files should compress with X-XTRA 
  20% to 55% faster.  In addition, compression has been improved over version
  3.05 as well.

- Authenticity Verification.  Using the BIOS type match up found in the 
  system, an automatically serial number will be created and use only for
  that system.

- A 500 byte "mini" PKSFX self-extracting module from the 1,221 byte
  in pervious PKZIP 3.05

- ZIP2EXE & PKZIPFIX utility have been implanted into PKZIP for ease.

- PUTAV have also been implanted into the PKZIP EXE file.
