Bill, Opera's changes to the Presto rendering engine have been more incremental and the version numbers more meaningful.

Opera 9.0, 9.2, 10.0, 10.5, 11.0, 11.1, 11.5 and 12.0 are examples of versions the past few years in which Opera has done more collectively each version than Mozilla has with any three versions of Firefox after Firefox 4.
