The Mozilla Project has posted
the first alpha of Sea Monkey,
"a community effort to deliver production-quality releases of code derived from the application formerly known as 'Mozilla Application Suite'.
Whereas the main focus of the Mozilla Foundation is on Mozilla Firefox and Mozilla Thunderbird, our group of dedicated volunteers works to ensure that you can have 'everything but the kitchen sink'".
XML support includes SVG, XSLT, CSS, and XHTML.
Opera Software has released version 8.5 of their namesake web browser for Windows, Linux, and the Mac. Opera is now free-beer: no ads, no license fee. Opera supports XML, XHTML, and CSS but not XSLT.
The Mozilla Project has released
version 1.0.7 of Firefox,
the open source web browser that is rapidly gaining on
Internet Explorer. Firefox supports HTML, XHTML, CSS, and XSLT.
MathML and SVG aren't supported out of the box, but can be added.
1.0.7 plugs several security holes and fixes bugs. All users should upgrade.
