Netscape decided to forgo releasing Netscape 5 in favor of waiting and releasing Netscape 6. Netscape 6 came out today, 5 April 2000. I downloaded it and tried it out and it is impressive.
The interface is different than you might be used to if you've used the Netscape browser in the past, but it's nice. For one thing it's small (356K for the program on Windows 98) as opposed to 5,434K for Netscape 4.7.
Here is the same screen shot on the three browsers, Netscape 4.7, Internet Explorer 5, and Netscape 6.
Look closely at how the fonts are rendered.
