I was just reading a run down by Dennis of all the new features in the new version of Opera Mini now that it is finally out of beta. With the Beta of 4.0 dragging out through versions 1, 2, and 3 we are finally seeing the results of all that testing. The most notable of the upgrades in the new 4.0 version were the much touted OperaLink and Desktop Rendering which have been improved in the final release.
