Subject says all - the next beta of KDE 3.0 is out, after a short delay. You can find the downloads at this announcement. Click below to read more details about this version.One of the most important things that the Konqueror teams wants from people are test cases of your regulary visited pages, where Konqueror either fails to render or render things incorrectly, and submit it using KDE's Bug Tracking system. URL's will not be helpful as it takes lots of time to strip a page from all the HTML code in order to find the actual problematic part of the web page.
Just to save the search for some people: Mandrake, SuSE, Slackware and Tru-64 binary packages are available now. Others will be available soon. Source code is of course available also.
