It was discontinued in 2000. However, the last version (2.0) may still be found on some Web sites for downloading.

Today, the HTML code used is very outdated and may not display more recent Web sites correctly. It does not support PNG images, and this limits its support on many sites where the newer PNG format has been adopted.
