you should not skip a major release.
Update to 3.0.4.6 now so you have the best basis for 3.0.5

Why did you not update to 3.0.4.x in the past?
If you are concerned with problems in the first release of a major version step you could wait for a 3.0.5.1 but if the build is as good as I aspect it to be it might take some time until a fix release .1 is released
