The Mozilla Organization open-source project is putting the final touches on the long-awaited version 1.0 of the Mozilla Web browser – four years after Netscape Communications released the source code. Mozilla.org's says it's "very close to the finish line for 1.0 – we look forward to celebrating Mozilla 1.0 shortly". The release candidate of version 1.0, which isn't yet finalized, will soon be available for download to allow wider testing and feedback before a final version 1.0 release or a second release candidate is ready, according to the group. Mitchell Baker, a spokesperson for Mozilla.org, says no date has been set for a final release. Last month, America Online said it was testing several open-source software products to run various parts of its Internet service, a move that could presage a shift from Microsoft 's Web-browsing software. The company, a subsidiary of AOL Time Warner, began testing software to run the Web browser bundled with its AOL Internet service software. The test version of the AOL software is powered by what is known as the Gecko rendering engine, which is the technology responsible for allowing Web pages to be displayed in a browser. Gecko powers the latest versions of the Netscape browser and is at the core of Mozilla.
