Default Prime95 version 29.6/29.7/29.8

Prime95 version 29.8 build 6 is available.

From whatsnew.txt:

Code:
1)  Support added for AVX-512 FFTs.
2)  FMA3 FFTs now have slightly higher FFT crossover points.  Soft crossovers are
    no longer used by default.  See undoc.txt.
3)  Torture test dialog box options now based on cache sizes.  Options for performing
    a weaker torture test are available.  Torture tests that use all RAM are now more
    stressful.  In-place vs. not in-place memory accesses now displayed on screen.
    On machines with more than 4GB of memory, blend defaults to 1/16th of RAM.
4)  Add & subtract operations for AVX-512 FFTs are now multithreaded.  This should
    improve performance for P-1 and ECM when using multiple threads.
5)  Benchmark results are now written to results.bench.txt.
6)  JSON results are now available for all work performed.  JSON results are
    written to results.json.txt.
7)  PRP tests with Gerbicz error checking are more immune to hardware errors.
This is a release candidate version. If no serious bugs are reported this will become the official release on the mersenne.org download page.

There are no known serious bugs. There should be no problem with replacing your existing prime95/mprime executable with the new one (the Gerbicz PRP changes will in rare situations cause a save file to be discarded and a previous save file used).

Thanks to all that helped reporting bugs during the AVX-512 development in the 29.5 thread.
