Fixed Wounded Cubic and Blaschke Triple Product formula critical point detection when using Abs modes.
Fixed a bug in numeric controls for formula parameters, where integer values allowed typing decimal places, although the actual values were rounded to the nearest integer.
Disabled Period testing for early bailout in Mandelbrots for Alternator and Coupling Loops formulas, as it could cause wrong results.
In the Help, added a Minibrot types topic in the Formula forays section.
Faster calculation for some Mandelbrot fractals with no lighting and In Set using Solid Color, if many pixels are In Set.
In the Julia panel, changed the default value of C real to 0.
Choosing any Chaotic formula now automatically changes to Julia mode and custom default coloring.
In the Formula panel, the Open Parameter File Using Formula dialog now has an option to Include Subdirectories.
Changed the Hypertile formula defaults from 2 3 6 to 2 4 5.
Improved sampling used for anti-aliasing, and increased maximum samples to 113.
Removed 97 sharper anti-aliasing option and added a Sharper Sampling button, that works with all anti-aliasing options.
Fixed a bug where renders taking less than a second did not update the Time in the status bar from the previous render.
Added Wounded Cubic formula in the Integer Powers category.
Added Real Expo formula in the Real Powers category.
Added Power Swap formula in the Hybrid category.
Fixed a bug in analysing critical points for Julia mode or explorer, which could result in Floating Point division by zero errors in rare circumstances.
Added Mean loglog option in the In Set color curve control.
Added 97 sharper option to the Anti-aliasing control. If the Render With Alpha Mask option is on then 97 samples is used instead.
Fixed bugs when importing Map files. The Gradient Category dialog would still import gradients if the Cancel button was clicked, and did not check for a blank category.
In the Help, added a Formula forays section with two topics on fractal types.
Fixed a bug where environment map files and preset files would not open if the extension was upper case.
