It happened @ 07:54 UTC on 2010-07-11, when I finished the DC of M20425091, proving that M20996011 really is the 40th Mersenne prime.

The line to add to the Milestones page is:

July 11, 2010: All exponents under 21 million have been doublechecked.

My mistake. The "All exponents below..." just changed, and I thought the previous one was 20.7M, but it was 21.07M.
