New features in Version 17.1 of prime95.exe

 

1.        The -T command line switch has been deleted.

 

2.        You can now fine tune your control of the program by adding Time= lines to your prime.ini file - see the readme.txt file.

 

3.        ECM factoring for 2^N+1 is now available.

 

4.        By default, ECM factoring stops if a factor is found for exponents above 5825 and continues (if the cofactor is composite) for exponents below 5825.  You can override this behavior by setting ContinueECM=0 or 1 in prime.ini.
