The engineers will most likely have it fixed by the first service release. For those needing higher resolutions, I suggested (until the fix is ready) to do what I usually do out of habit: multiply the desired height or width in inches by the desired dpi to figure out what my dimensions would be.

Let's say I want an image that's 11 inches tall and 14 inches wide at 300 dpi. So the equivalent  would be 11x300 =3300 and 14x300=4200 which means I'd render out at 3300x4200x72 dpi to get the same resolution.
