Mozilla foundation has decided to increase the version number of the next major release to 1.5 from 1.1, reflecting the sheer number of bug fixes and features that have been worked into the next version of the browser.

We are planning for a Firefox 2.0 and 3.0, but will divide the planned work over (at this point) three major Milestones, 1.5 (September 2005), 2.0 (unscheduled) and 3.0 (unscheduled). All major development work will be done on the Mozilla trunk, and these releases will coincide with Gecko version revs.
