No changes, other than the max multiplier is now 14 rather than 12. For example, the maximum stat contribution from virtues for which a stat is the primary benefit is now 42 (14 x 3), up from 36 (12 x 3).
EDIT: I just double-checked on Bullroarer, and compared the multipliers for each benefit to the Lotro virtue wiki. It looks as if there are no appreciable changes to the multipliers; all benefits will improve equally.
Of course, this may change when the update goes live.
The bottom line is that there is no change in the benefits from each virtue; the ones you like now at 12 you will like even better at 14!
