Kalles Fraktaler 2 + development is mostly stopped from my side.

Here are some KF2+:

- FractalShades (Python)
- Fractal Zoomer (Java)
- Fraktaler 3 (C++)

For more details see:
mathr.co.uk/kf/kf.html#future

Important KF bug fixes may still be released from time to time, but I do not have enough time to implement the () optimisation in this project.

BLA is much better than and (which is called NanoMB1 in KF), in terms of efficiency of calculations, generality of applicability, simplicity of implementation, and robustness of results.

github.com/smurfix/kf2/commits
Someone has enthusiastically forked (which I forked from the original in 2017 or so) and started a lot of the boring work to separate the engine from the graphical user interface, opening the door to alternative GUIs on non-Windows operating systems (even though it worked in Wine, that was limited to x86_64).

Unfortunately due to the lack of documentation on my part some of the commits caused problems and I had to revert, but the majority was fine. I started a branch for kf-2.16, because I still want to fix some bugs in the 2.15 series.

I haven't tested the Linux version yet, but the Windows version seems still to work fine in my brief tests.

Important errata notice for kf-2.15.5

There is a severe bug in scaled double rendering in conjunction with the new single reference method which causes bad images: recommended workaround is to disable Rescaled Double in the Number Type Selection dialog accessed from the Advanced menu.

Impact of the workaround: it'll slow down a bit beyond e300 or so, especially for exceedingly deep zooms beyond e4900 or so. (But it will probably still be faster than using the multiple reference methods with glitch correction after the fact.)

kf-2.15.5 released!

full announce: mathr.co.uk/blog/2021-12-05_kf

highlights include single reference implementation for glitch avoidance (as suggested by Zhuoran on fractal forums), and lots of new formulas (mostly from FractalAlex)

this is probably the last kf release from me for the foreseeable future...

What to do about the Examine Zoom Sequence feature of (a explorer)?

It's probably no longer necessary now that Reuse Reference (which saves computation time at the expense of memory) can be used together with Auto Solve Glitches (which is needed for correct images)?

It used to be (in the distant past) that zoom out sequences were full of glitches and you'd have to scroll through and correct them later, but the code rotted and there are loads of bugs (it doesn't support iteration data in EXR, only KFB, it doesn't write out corrected PNGs etc, only JPEGs, minimizing the window can corrupt the whole zoom sequence, ...).

There is also a poll here:
