Release notes for 2820 firmware v3.3.4.1 claims "Firmware 3.3.4.1 provides significant improvements and new features for Vigor2820 series owners." However, there are no new features listed and only 2 changes. The previous version 3.3.4 lists 4 new features and 105 changes. That suggests it is version 3.3.4, not version 3.3.4.1, that provides "provides significant improvements and new features", and it further implies that the cautions listed in 3.3.4.1 actually apply to version 3.3.4

Can anyone confirm?
