According to a report by webmonkey, the final version of Firefox 3.5 will be released on June 30.
Firefox 3.5 is the first major revision since 3.0 was released about a year ago. The new version sports a faster rendering engine, stability enhancements and a new javascript engine. It will also include support for the most widely-used elements of HTML 5 that allows for offline data access, enhanced web graphics and multimedia playback without plug-ins. The Firefox logo has also had a small revision as well.
Mozilla has been showing different 3.5 features within a 35 day period, and has also shown the new tools developers can take advantage of in the new version.
The new version was originally going to be 3.1, but was renamed to 3.5 later to reflect a greater scope of changes than what has originally been planned.
