# CC: R Version VS CC: T Version # CC: R Version VS CC: T Version
CC: R Strives to maintain perfect pairity with CC: T, however in some cases this is not possible, so CC: R might have a "newer" version than what CC: T has, these newer versions will be primarily bugfixes and the like because fabric is "weird" when porting a forge mod.
