[newbie] Netscape

[Herman Christiani]

Hi All,
Can somebody tell me what is the latest 4.7x version of Netscape?
I'm running 4.73, after trying to find a later version I was told
by Netscape that I was already running the latest version for my 
platform (MD 7.1), afaik the latest is 4.76, will this not run on
MD 7.1?
TIA, Herman
