It is not Nestcape V3, but -- from the read.me:
(From ftp site service2.boulder.ibm.com/software/netscape)
  This release of Netscape Navigator offers you all the features of
  Netscape Navigator 2.02 and more.  Highlights include:
  *  Features of Navigator 3.0 for improved quality
  *  Extended drag and drop support for URL objects
  *  Voice Navigation to surf the Net with Navigator
  *  Native OS/2 multimedia plug-ins, installed through the
     associated OS/2 Plug-In Pack
  *  Support for Windows 3.1 plug-ins, also installed
     through the OS/2 Plug-In Pack
  *  Plug-in toolkit
  *  Command line options
  *  International document encoding support including DBCS
3.1 Drag and Drop
-----------------
  The following drag and drop operations are available on
  all versions of OS/2 Warp:
  - Support for Images dragged to a folder and back into the HTML
    window.
  - Support for drag and drop pages to a printer object.
  - Support for drag and drop mail items into folders.
  - Support for drag and drop news and mail items to the Desktop
    from the item itself, not from the list boxes.

3.2 Voice Navigation
--------------------
  A new menu item named 'Links' has been added to the menu
  bar that lists links from the most recently seen parts of
  a page. In OS/2 Warp version 4, users can use voice
  navigation to surf the net and interact with Netscape
  Navigator for OS/2.
3.3 Java
--------
  By default Java support is enabled during installation. You
  can turn the Java support off by checking the Disable Java
  check box on the General page of the Security Preferences.

( I know, this is old news now, but reading through all the previous messages
about this version, I didn't see much about what was new in the OS2EN202 )
PS
My experience in upgrading was that some of the "bullet" items in lists
appeared as a strange character - like a lower case b or p.
It was fixed after I took the Option - Document Encoding.
