With a growing project, it's difficult to keep track of all the "special" milestones. However, many hands make light work. Therefore, please feel free, if you see something extra special, to post in this thread or PM me. I'll use the PG Milestones & Significant Primes thread as a main collection center. Thanks for your help!

EDIT: As for individual milestones, please see Free-DC Stats: PrimeGrid. Bok has done some excellent work with cobblestone and badge milestones.

2009 July - PS3 support added to AP26 application

2009 December - CUDA support added to AP26 application
