SVG implementations

I'm trying to find information on the various implementations of viewers, 
editors, and toolkits for SVG. The page on w3c.org seems out of date.
For instance, the listing for Amaya claims the last update was in 
October, 2001, version 5.2. The Amaya release history documents 
version 6.4 from a couple weeks ago.

Are there other sites listing the various tools/apps and their progress
on supporting the recommendation?

 Thanks,

 Joe
