# NEW FEATURES IN VERSION 12.x of PRIME95.EXE

## New Features in Version 12.4 of Prime95

1. A minor bug in the Pentium factoring code has been fixed.
2. When creating an intermediate file, instead of deleting the previous intermediate file it is renamed just in case there is a machine crash before the new intermediate file is written to disk.
3. Factoring is now 6% faster.
4. The program is now "network-enabled". See network.txt for more details.
5. A bug in stopping and continuing when factoring in Version 8 has been fixed.

## New Features in Version 12.3 of Prime95

1. The -h command line argument is now available.
2. Save files are generated every half-hour when factoring.

## New features in Version 12.2 of Prime95

1. A minor bug in the factoring code has been fixed.

## New features in Version 12.1 of Prime95

1. Command line arguments are now available to help you run the program on your co-worker's machines!

## New features in Version 12 of Prime95

1. The program is faster! Expect to see improvements of 8 to 15%. The faster your CPU, the more improvement you should notice. The program also uses less memory.
2. There are now 5 separate hour-long self tests - one for each possible FFT length. You will run one of the new one-hour self tests even if you passed the self test in the previous version.
3. The program can now test exponents as high as 2,630,000!
4. The user interface has changed.
   1. You no longer enter a 3 or 4 digit range. Rather you enter an explicit starting and stopping point. For example, in the previous version you would enter 1234 for the range. In this version you enter a starting point of 1234000 and an ending point of 1234999. This makes it much easier to "check out" just part of a range. It also makes it easier to split a range among two or more machines.
   2. The "Only Find Factors" checkbox has been replaced. Use the Range / Factor menu choice instead.
   3. The Range / Double Check menu choice has been added for those of you who are double checking previously checked exponents.
   4. The Advanced / Password menu choice is now used to activate the rest of the Advanced menu.
5. The program now performs two new error checks every iteration! These will help guard against memory errors or "cosmic ray" errors. These new checks will not catch all such problems but should catch the vast majority.
