From the GTE rules (

Quote:
Except for safety or reliability reasons, only one evolution per period of 2 years is permitted before the first event of the season in which the homologated model is entered. This evolution will have the current year of the manufacture and will not be allowed on the cars from previous periods if a competitor wants to run in LMGTE-AM.
The period of restriction will begin for 2013 models for LMGTE-PRO cars, it will be the same for every car.

So, you can only do one update within two years. The rule came in starting from 2013, and obviously all cars were updated in 2013. That sounds to me like an effective development freeze for 2014 (although probably badly translated from French
). New cars for 2014 like the C7R aren't affected because they aren't homologated yet. The Porsches were upgraded because of this sentence:

For the new cars homologated, 1 evolution during the season will be allowed the first year.
