Anyone know the status of vol 4 and "ultimate edition" of vol 1-3?
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-...
This https://cs.stanford.edu/~uno/taocp.html seems up to date.
> All of the MIX programs in Volumes 1--3 will need to be rewritten in MMIX, before I finish the ``ultimate'' edition of those volumes that I plan to write after Volume 5 is completed. The current target date for the ultimate volumes is the year 2020, so there is plenty of time to do the conversion. But I think it will be an instructive undertaking if different groups of students from around the world try to do the necessary translations first, perhaps in friendly competitions, long before I get into the act.
As to the ultimate versions (or even finishing until volume 5): not to be morbid, but the date there has been continually pushed back, and Dr. Knuth is not a young man.
