M617 Factored

M617 has been completely factored by the Special Number
Field Sieve (SNFS). It was previously known that

Starting at about M13, you see that there are indeed islands:

The Status estimate of the chance that the number you are testing seems to
be off by a factor of e, based on Wagstaff's estimate.

appropriate amount of trial factoring - if you didn't do enough, and
proceed to run the LL test, you lose the credit because you should
This doesn't fit with my understanding of how Prime95 works. I
How large will the exponent be for a 10,000,000 digit prime number?
To be a 10,000,000 digit prime number the exponent must be at least
33,219,281 (which also happens to be a Mersenne candidate).
Has the prime number that was found a week ago been announced on this
list?
I.E. What number was
