Welcome to PKZIP for Windows, Version 2.70!


New features available in this release
----------------------------------------

PKZIP 2.70 for Windows 9x/NT 4.0 has many new and useful features.

  * Create Self-Extracting Patch Files (Professional Distribution 
    Licensed version only)
          
          PKZIP for Windows allows you to create self-extracting 
          patch files. Patch files can be an ideal solution for 
          distributing software updates. Please refer to the User's
          Manual or online help (PKZIPW.HLP) for further information
          on creating patch files. 

  * Email MAPI (i.e. Send To) Support
          
          PKZIP for Windows allows you to Email archive files right 
          from the main application window. 

  * Embed Authenticity Verification (AV) Information (Registered and 
    Distribution Licensed versions only)

          You may embed an electronic signature with files stored in 
          a .ZIP archive and subsequently authenticate those files 
          upon extraction. PKWARE Authenticity Verification (AV) 
          information allows you to detect whether a .ZIP file's 
          integrity has been compromised. The putav.bat file will
          configure PKZIP for Windows for Authenticity Verification.
          Please refer to the User's Manual for further information
          on configuring and using AV.
 
  * Self-Extractors for Several New Platforms (Professional 
    Distribution Licensed version only)

          You may create self-extractors for several new platforms
          (e.g. UNIX) with the PKSFXS.DAT file. This file is on the 
          diskette labeled Additional Self-Extractors. Copy this file
          from the diskette and place in the installation directory. 
          The available self-extractors will appear in the Save As 
          dialog in the Save as type drop down list. Please refer to 
          the User's Manual for further information on configuring
          and using the pksfxs.dat file.

  * Enhanced 32-bit Windows Self-Extractor (Registered and 
    Distribution Licensed versions only)
    
          PKZIP for Windows includes the ability to create 32-bit 
          self-extracting (Explorer enabled) Windows archives to run
          on Windows 9x and Windows NT.

  * Extended configuration options for Windows self-extractors 
    created with the Registered version of PKZIP for Windows
  
          Self-extracting .ZIP files created with the Registered 
          version of PKZIP for Windows now feature several 
          configuration options (e.g. Customizable Title Bar) 
          previously only available in the Professional Distribution 
          Licensed version of PKZIP for Windows.    

  * Improved Self-Extractor Run After Extraction Functionality 
    (Registered and Distribution Licensed versions only)

          This extended functionality allows you to do such things as
          run an installation script (i.e. .INF file) after 
          extraction. Please refer to the User's Manual for detailed
          information.


Program Updates from version 2.6x to 2.70
-------------------------------------------

  * Certain users reported that it took somewhat longer to open .ZIP 
    files in PKZIP 2.60 for Windows than in previous versions.
    Latest Version fixes logic that may have caused such behavior.

  * Fixed problem related to selecting the Overwrite:Never option 
    when creating/running Windows self-extractors.
    
  * File attributes are now restored with the files upon extraction 
    from Windows self-extractors.

  * Resolved performance issues when compressing files on network 
    file systems.
    
  * Fixed problem with certain files (Compression Method=Normal)
    reporting warning (e.g. '...bad compression block type') or error
    messages on extraction.
    
  * Fixed problem on certain NT systems where PKZIP didn't recognize
    the first diskette from a spanned set even if there was seemingly
    no problems with the diskette itself or the data written on that
    diskette.
    
  * PKZIP now properly extracts .TAR.GZ files as well as UUEncoded 
    .ZIP and .TAR files to the specified temporary extraction 
    directory.
    
  * Added Help button to the View Preferences dialog.
  
  * Modified the output format of Authenticity Verification warnings
    so they are easier to view and/or interpret.
    
  * Fixed problems and added functionality in the Wizard related to 
    accessing network file systems.

  * Fixed incorrect date/version information specified (via Explorer) 
    in the pkzipw.exe Properties dialog.
