Version Differences 
With all the new browser versions out from Netscape, I had gotten somewhat confused by their terminology so I set out to find out what the terms all mean and to try to give an explanation here. This is ALL dependent on the original file NOT having been tampered with or renamed. 

Version 3 terms 

1. If the filename begins with the letter "n" the package contains a browser, mail, news and "Cool Talk" voice communication clients.
2. If the filename begins with the letter "g" the package is designated the "Gold" version and in addition to the above, it also has a graphical html editor built-in.

Version 4 terms 

1. If the filename begins with the letter "c" the package contains a browser, email, news, and editor

• Contains Navigator, Composer, Messenger, Collabra, Netcaster, Cosmo Player (32bit) or Live 3D(16bit) and Conference.

2. If the filename begins with the letter "p" the package contains all of the above and:

• Calendar- a dayplanner type applet
• IBM Host on demand- 3270 client application
• AutoAdmin containing AutoUpdate which allows System Administrators to securely and automatically update plugins, and Communicator components and AutoConfig which allows centralized configuration and automatic scheduled updating of client preferences and user interface. To take advantage of the AutoAdmin component, you must have the Netscape Administration Kit

3. I am awaiting word from Netscape Communications as to what the significance of "n" filename is in Communicator, though I believe it to be a one-time thing for the distribution of "Netcaster".
