SegWit was the hard fork, where it broke away from the original whitepaper. OP_CAT did exist, then was disabled on BTC then after BCH did a ticker fork from BTC after BTC protocol forked, OP_CAT was re-enabled, which carried onto BSV. BTC has done other forks since then, but SegWit and Taproot were the 2 big hard forks that truly changed it
