-This BIP reintroduces OP_CAT in the form of a new tapscript opcode which allows the concatenation of two values on the stack. This opcode would be activated via a soft fork by redefining the opcode OP_SUCCESS126 (the opcode 0x7e).
+This BIP reintroduces OP_CAT in the form of a new tapscript opcode which allows the concatenation of two values on the stack.

 When evaluated the OP_CAT instruction:
 # Pops the top two values off the stack,
