Patch 5 to Fractint version 20.4 is now available on the Fractint Developer's web sites: www.fractint.org or www.fractint.net This is unrelated to Rich's port. What's new: Changed help screen to show just two main authors - decided better not to show inactive authors. Added commented out bf version of Mandelbrot in fractalp.c. Giving thought to offering bfmath as an option to bnmath, but if we fix the current bignum problems, this may be moot. Added interation to <tab> screen. Fixed the logic for calculating when to switch from using a grid to using the on-the-fly calculation of an image's pixels. The logic was not handling disk video images sized above 2048x2048 with floating point enabled. Added the savename to the disk video status screen. Fixed bug in the compare routine of bn_math that fixes long standing problem with periodicity checking in deep zoomed images. Added code to force periodicity=0 when the inside=atan feature is used.
