Vol 4A was published in 2011: https://www.amazon.com/Art-Computer-Programming-Combinatoria...

Vol 4B was partially published in fascicles: https://www.amazon.com/Art-Computer-Programming-Fascicle-Pre... and https://www.amazon.com/Art-Computer-Programming-Fascicle-Sat...

Instead of the ultimate edition of vols 1-3, so far we've got a "patch" by Martin Ruckert who coordinated the volunteers: https://www.amazon.com/MMIX-Supplement-Computer-Programming-...

While we're posting Amazon links,

http://www.amazon.com/Art-Computer-Programming-Combinatorial...

has a fascinating 200+ page section on Boolean and bitwise tricks and techniques (Knuth: "A trick is a clever idea that can be used once, while a technique is a trick that can be used at least twice.").
