Not that recent. The 8008 used carry lookahead for example. And several 74181 (a 4-bit ALU chip which you can use multiple of in a group to build a wider ALU) could be combined with the 74182 (lookahead carry generator) to build an ALU with carry lookahead. These things are ancient (70's era tech).

That does not mean that carry lookahead addition was always used everywhere, some chips were really trying to save on transistors and didn't use it. But anything modern, probably has some sort of fast adder. Ripple carry adders do not scale well (imagine a 64-bit ripple carry adder, yikes) and transistors are significantly cheaper than a dime a dozen.
