-Remove the Type field from the variations tree and instead just put the type indicator icon next to the variation name.
-Double clicking to toggle variation parameter spinners now resets the value to the default if there is one, else it uses zero. If it is already using the default, it is toggled to 0.
-Add a new button to toggle xaos on and off.
-When duplicating a flame, insert it immediately after the one being duplicated instead of at the end of the file.
-When switching between flames in a file, keep the same xform index selected rather than resetting it to the first xform each time.
-Create a threaded writer for the final render and EmberAnimate so the rendering process does not get delayed by file saving which may take a long time.
-Remove warning which said "Frames per rot cannot be greater than one while Rotations is zero" when generating a sequence.
-Add the Circle_Rand variation from Chaotica.
-Add tool tips to clarify the following items:
--Auto Unique Filenames checkbox in the options dialog.
--Xaos table headers.
--Bug fixes
-Generating sequences using the following variations would be done incorrectly: circletrans1, collideoscope, crob, curlsp, glynnsim1, glynnsim2, hypercrop, julian, julian, mobiusn, nblur, waves2, wavesn.
-Adding/removing nodes from the color curve had accidentally been disabled.
-The applied xaos weight table was not showing normalized weight values.
-Changing the size of a flame was not observing the Apply To All checkbox.
-Do not clamp the Rotate field to +/-180, because this causes the rotation to switch from CW to CCW during sequence generation. Instead, leave it exactly as the user entered it so the rotations proceed in the same direction.
-Add new preset dimensions to the right click menu of the width and height fields in the editor.
-Change QSS stylesheets to properly handle tabs.
-Make tabs rectangular by default. For some reason, they had always been triangular.
--Bug fixes
-Incremental rendering times in the editor were wrong.
--Code changes
-Migrate to Qt6. There is probably more work to be done here.
-Migrate to VS2022.
-Migrate to Wix 4 installer.
-Change installer to install to program files for all users.
-Fix many VS2022 code analysis warnings.
-No longer use byte typedef, because std::byte is now a type. Revert all back to unsigned char.
-Upgrade OpenCL headers to version 3.0 and keep locally now rather than trying to look for system files.
-No longer link to Nvidia or AMD specific OpenCL libraries. Use the generic installer located at OCL_ROOT too.
-Add the ability to change OpenCL grid dimensions. This was attempted for investigating possible performance improvments, but made no difference.
This has not been verified on Linux or Mac yet.
-Add a new option to EmberAnimate --ignore-existing which makes it skip rendering a frame if the files from all of the requested extensions for that frame already exist.
--Code changes
-Migrate to VS2022 and no longer use a version specific folder for the VS solution and project files. It is now under a version agnostic folder called Solution.
--User changes
-Allow users to set the Exp value when using the Exp temporal filter type.
-Set the default temporal filter type to be Box, which does not alter the palette values at all during animation. This is done to avoid confusion when using Gaussian or Exp which can produce darkened images.
--Bug fixes
-Sending a sequence to the final render dialog when the keyframes had non zero rotate and center Y values would produce off center animations when rendered.
-Temporal filters were being unnecessarily recreated many times when rendering or generating sequences.
-Exp filter was always treated like a Box filter.
--Code changes
-Add a new member function SaveCurrentAsXml(QString filename = "") to the controllers which is only used for testing.
-Modernize some C++ code.
-Allow for specifying linear or smooth interpolation when generating a sequence in the Library tab (was formerly hardcoded to smooth). This has the effect of exposing the --unsmoother option used in EmberGenome in the GUI.
-Clarify tool tips of the sequence interpolation fields in the animation group on the Flame tab.
-Change caption of the Bounds tab to be Bounds & Log.
-Entering xaos cells will always select the entire cell to make editing easier.
-Add radio buttons on the xaos tab to specify how pasting or duplicating xforms should preserve xaos.
--Bug fixes
-The left header column in the xaos visualization table had somehow disappeared.
--Code changes
-DoubleSpinBox now has a boolean which specifies whether it clears its selection on enter. Default true.
-Make AddXformsWithXaos() be a static member of FractoriumEmberController for quicker build times.
-Add new exmaple flames to package_linux.sh
-Allow dragging in folders which will be recursively traversed for flame files.
-Allow for adjusting scale via keyboard with the < and > keys.
-Show the count of opened flames on the header of the library tree.
--Bug fixes
-Attempt to preserve xaos when pasting xforms.
--Code changes
-Default flam3 compatibility mode to true.
-Add backward compatibility option for the following variations: cos, cosh, cot, coth, csc, csch, sec, sech, sin, sinh, tan, tanh.
-Add the ability to re-order variations by dragging them in the Info tab.
-Optimization and correction for hexaplay3D and hexnix3D.
-Major optimization on the GPU for flames which only have one xform, by skipping all random xform selection code.
-Changes to how xaos is "preserved" when adding new xforms, copying xforms and duplicating xforms.
--Duplicating xforms when no xaos is present in the flame now maintains not using xaos, and keeps all values as one.
--Duplicating xforms when xaos is present, will result in xaos rows and columns that are the same as the xforms being duplicated, with the new row and column area having values of 1.
--Duplicating xforms when xaos is present, while Control is pressed, will result in xaos rows and columns that have values of 0, with the new row and column area having values of 1.
---Copying xforms has the same behavior as duplicating with Control pressed.
--Bug fixes
-hexaplay3D, hexnix3D and post_smartcrop were wrong on the GPU because they are the rare variations which preserve state between iterations.
-Changing the sub batch size would improperly wrong the wrong number of iterations.
--Code changes
-Some functions in Affine2D made const.
-Change in the index at which points and variation state are preserved between kernel calls.
-Some arguments in some member functions of GLEmberController made const.
-Allow for saving EXR as full 31-bit float per component per pixel.
-Allow for saving the output from the final render dialog as a different image format without starting the rendering process over.
--Code changes:
-Make StripsRender() handle memsetting the final output image so calling code no longer has to.
-Make FinalRenderEmberController<T>::SaveCurrentRender() return the path that the image was actually saved to.
-Allow the user to resume a finished render in the final render dialog with a higher quality. This only applies to rendering a single image with no strips.
-Make clear xaos apply to all when Apply All is checked.
-Fix some potential OpenCL compilation bugs on circlecrop, circlecrop2, oscilloscope2, Truchet_hex_crop.
-Prevent the minus key from changing the current xform when being pressed in a textbox.
--Code changes
-Cleanup some casting in depth_blur, depth_blur2.
-Show common folder locations such as documents, downloads, pictures in the sidebar in all file dialogs.
-Warning message about exceeding memory in final render dialog now suggests strips as the solution to the problem.
-Strips now has a tooltip explaining what it does.
-Allow more digits in the spinners on the color section the flame tab.
-Add manually adjustable size spinners in the final render dialog. Percentage scale and absolute size are fully synced.
-Default prefix in final render is now the filename when doing animations (coming from sequence section of the library tab).
-Changed the elliptic variation back to using a less precise version for float, and a more precise version for double. The last release had it always using double.
-New applied xaos table that shows a read-only view of actual weights by taking the base xform weights and multiplying them by the xaos values.
-New table in the xaos tab that gives a graphical representation of the probability that each xform is chosen, with and without xaos.
-Add button to transpose the xaos rows and columns.
-Add support for importing .chaos files from Chaotica.
--Pasting back to Chaotica will work for most, but not all, variations due to incompatible parameter names in some.
-Curves are now splines instead of Bezier. This adds compatibility with Chaotica, but breaks it for Apophysis. Xmls are still pastable, but the color curves will look different.
--The curve editor on the palette tab can now add points by clicking on the lines and remove points by clicking on the points themselves, just like Chaotica.
--Splines are saved in four new xml fields: overall_curve, red_curve, green_curve and blue_curve.
-Allow for specifying the percentage of a sub batch each thread should iterate through per kernel call when running with OpenCL. This gives a roughly 1% performance increase due to having to make less kernel calls while iterating.
--This field is present for interactive editing (where it's not very useful) and in the final render dialog.
--On the command line, this is specified as --sbpctth for EmberRender and EmberAnimate.
-Allow double clicking to toggle the supersample field in the flame tab between 1 and 2 for easily checking the effect of the field.
-When showing affine values as polar coordinates, show angles normalized to 360 to match Chaotica.
-Fuse Count spinner now toggles between 15 and 100 when double clicking for easily checking the effect of the field.
-Added field for limiting the range in the x and y direction that the initial points are chosen from.
-Added a field called K2 which is an alternative way to set brightness, ignored when zero.
--This has no effect for many variations, but hs a noticeable effect for some.
-Added new variations:

--Bug fixes:
-Bounds sign was flipped for x coordinate of world space when center was not zero.
-Right clicking and dragging spinner showed menu on mouse up, even if it was very far away.
-Text boxes for size in final render dialog were hard to type in. Same bug as xform weight used to be so fix the same way.
-Fix spelling to be plural in toggle color speed box.
-Stop using the blank user palette to generate flames. Either put colored palettes in it, or exclude it from randoms.
-Clicking the random palette button for a palette file with only one palette in it would freeze the program.
-Clicking none scale in final render did not re-render the preview.
-Use less precision on random xaos. No need for 12 decimal places.
-The term sub batch is overloaded in the options dialog. Change the naming and tooltip of those settings for cpu and opencl.
--Also made clear in the tooltip for the default opencl quality setting that the value is per device.
-The arrows spinner in palette editor appears like a read-only label. Made it look like a spinner.
-Fix border colors for various spin boxes and table headers in the style sheet. Requires reload.
-Fix a bug in the bwraps variation which would produce different results than Chaotica and Apophysis.
-Synth was allowed to be selected for random flame generation when using an Nvidia card but it shouldn't have been because Nvidia has a hard time compiling synth.
-A casting bug in the OpenCL kernels for log scaling and density filtering was preventing successful compilations on Intel iGPUs. Fixed even though we don't support anything other than AMD and Nvidia.
-Palette rotation (click and drag) position was not being reset when loading a new flame.
-When the xform circles were hidden, opening and closing the options dialog would improperly reshow them.
-Double click toggle was broken on integer spin boxes.
-Fixed tab order of some controls.
-Creating a palette from a jpg in the palette editor only produced a single color.
--Needed to package imageformats/qjpeg.dll with the Windows installer.
-The basic memory benchmark test flame was not really testing memory. Make it more spread out.
-Remove the temporal samples field from the flame tab, it was never used because it's only an animation parameter which is specified in the final render dialog or on the command line with EmberAnimate.
--Code changes:
-Add IsEmpty() to Palette to determine if a palette is all black.
-Attempt to avoid selecting a blank palette in PaletteList::GetRandomPalette().
-Add function ScanForChaosNodes() and some associated helper functions in XmlToEmber.
-Make variation param name correction be case insensitive in XmlToEmber.
-Report error when assigning a variation param value in XmlToEmber.
-Add SubBatchPercentPerThread() method to RendererCL.
-Override enterEvent() and leaveEvent() in DoubleSpinBox and SpinBox to prevent the context menu from showing up on right mouse up after already leaving the spinner.
-Filtering the mouse wheel event in TableWidget no longer appears to be needed. It was probably an old Qt bug that has been fixed.
-Gui/ember syncing code in the final render dialog needed to be reworked to accommodate absolute sizes.
-Attempt to preserve xaos when adding xforms. Note this is not an exact copy, but just a preservation of some values based on position.
-Add some acceleration to the changing of spinner values when dragging the right mouse button to adjust.
-Make the pivot be the center of the viewable area when doing drag/rotate/scale with the right mouse button.
--Clamp minimum scale to 10
--Draw a line from the mouse position to the pivot.
-Keep a cache of the last added final xform with each flame so that it can be quickly added, removed, then added back for testing its effect.
--This is not saved with the xml file and is solely for interactive editing.
--Bug fixes
-File filtering in open and save dialogs were broken.
-Right clicking on integer spin boxes was causing the context menu to pop up, when it should be supressed just like double spin boxes.
-Deleting xforms was still broken.
--Code changes
-Refactor the code for adding and pasting xforms into a single global static function called AddXformsWithXaos().
-Allow running from outside of the folder the executable is in on Windows, by adding the install folder to the PATH variable. This was needed to properly find the palette file (even though it's mostly unneeded).
--Bug fixes
-Strips renders crashed.
-Better handling of large memory allocations by forcing a free of previous allocations.
-Final render dialog did not properly save last used extension setting.
-Density filtering progress bar in final render dialog did not update if only log scaling was being used.
--Add support for Exr files which use 32-bit floats for each RGBA channel. Seems to come out too washed out.
--Allow for clearing an individual color curve.
--Allow for saving multiple image types in EmberRender and EmberAnimate. All writes are threaded.
--Remove --bpc command line argument. Add format png16 as a replacement.
--Remove --enable_jpg_comments and --enable_png_comments command line arguments, and replace them with --enable_comments which applies to jpg, png and exr.
--Add menu items to variations and affine spinners which allow for easy entry of specific numeric values like pi.
--Make final render dialog be wider rather than so tall.
Bug fixes:
--Fix some OpenCL compile errors on Mac.
--Remove ability to save bitmap files on all platforms but Windows.
Code changes:
--New dependency on OpenEXR.
--Allow Curves class to interact with objects of a different template type.
--Make m_Curves member of Ember always use float as template type.
--Set the length of the curves array to always be 2^17 which should offer enough precision with new 32-bit float pixel types.
--Set pixel types to always be 32-bit float. This results in a major reduction of code in the final accumulation part of Renderer.h/cpp.
--Remove corresponding code from RendererCL and FinalAccumOpenCLKernelCreator.
--Remove Transparency, NumChannels and BytesPerPixel setters from Renderer.h/cpp.
--Add new global functions to format final image buffers and place all alpha calculation and scaling code in them.
--Blending is no longer needed in OpenGLWidget because of the new pixel type.
--Make new class, AffineDoubleSpinBox.
--Attempt to make file save dialog code work the same on all OSes.
--Remove some unused functions.
--User changes
-Add support for adjusting xform color indices in the palette editor. Fixed palettes can now be displayed there, but they will have no color arrows as they are not editable.
-Add support for independent dimension scaling in the EmberRender and EmberAnimate programs to bring them in line with the final render dialog Fractorium.
--Bug fixes
-File paths with a space in them did not work in the command line programs.
-Any Xml file in the search paths would erroneously be treated as a palette file.
--Code changes
-Change some for loops to while loops when iterating through xforms.
-Allow FractoriumEmberController<T>::UpdateXform() to be able to apply the action to an xform at a specific index.
-Remove old code blocks build files that were never used.
-Make GetPath() return empty string if no path is present in the passed in file path.

-Add a palette editor.
-Add support for reading .ugr/.gradient/.gradients palette files.
-Allow toggling on spinners whose minimum value is not zero.
-Allow toggling display of image, affines and grid.
-Add new variations: cylinder2, circlesplit, tile_log, truchet_fill, waves2_radial.
--Bug fixes
-cpow2 was wrong.
-Palettes with rapid changes in color would produce slightly different outputs from Apo/Chaotica. This was due to a long standing bug from flam3.
-Use exec() on Apple and show() on all other OSes for dialog boxes.
-Trying to render a sequence with no frames would crash.
-Selecting multiple xforms and rotating them would produce the wrong rotation.
-Better handling when parsing flames using different encoding, such as unicode and UTF-8.
-Switching between SP/DP didn't reselect the selected flame in the Library tab.
--Code changes
-Make all types concerning palettes be floats, including PaletteTableWidgetItem.
-PaletteTableWidgetItem is no longer templated because all palettes are float.
-Include the source colors for user created gradients.
-Change parallel_for() calls to work with very old versions of TBB which are lingering on some systems.
-Split conditional out of accumulation loop on the CPU for better performance.
-Vectorize summing when doing density filter for better performance.
-Make all usage of palettes be of type float, double is pointless.
-Allow palettes to reside in multiple folders, while ensuring only one of each name is added.
-Refactor some palette path searching code.
-Make ReadFile() throw and catch an exception if the file operation fails.
-A little extra safety in foci and foci3D with a call to Zeps().
-Cast to (real_t) in the OpenCL string for the w variation, which was having trouble compiling on Mac.
-Fixing missing comma between paths in InitPaletteList().
-Move Xml and PaletteList classes into cpp to shorten build times when working on them.
-Remove default param values for IterOpenCLKernelCreator<T>::SharedDataIndexDefines in cpp file.
-Change more NULL to nullptr.
--User changes
-Add many tooltips to help clarify functionality.
-Select multiple flames in library for del/move. Still only one allowed to be set as the current.
-Show checkbox for current flame. Remember this is not necessarily what's selected.
-User can now drag a square to select xforms, which keeps in sync with checkboxes.
-Remove --nframes from command line. Replace with new params: --loopframes, --interpframes, --interploops.
-Add two new options to EmberGenome: --cwloops --cwinterploops to specify whether rotation should go clockwise instead of the default counter clockwise.
-Add these to Fractorium as checkboxes.
-Apply All now also works for toggling animate flag on xforms.
-Options dialog now allows user to set whether double click toggles spinners, or right click does.
--Bug fixes
-Selecting final and non-final xforms, and then dragging the non-final did not drag the final with it.
-Selecting all xforms when a final was present, then deleting crashed the program.
-Remove support for ppm files in the command line programs, it's an outdated format.
-Switching between SP and DP kept reapplying the palette adjustments.
--Code changes

-Add animation sequence creation to Fractorium.
-Add two new options to EmberGenome which are used when generating an animation sequence.:
--startcount: Add this number to the filename of each flame.
--padding: Override the automatically calculated amount of padding zeroes added to each filename.
--Bug fixes
-Prevent filenames in command line programs from using scientific notation when rendering a large number of frames.
-Fix tab orders to match newer GUI items which were overlooked in previous releases.
-Re-render previews if transparency value in the options dialog was changed. Re-rendering was previously only done if early clip or y axis up was changed.
-Use transparency when rendering thumbnail previews.
--Code changes
-Wrap EmberCommon.h in a namespace called EmberCommon.
-Move FormatName() from EmberGenome to EmberCommon.h/cpp
-Add a prefix parameter to EmberFile::DefaultFilename() to allow for creating a default filename for sequences.
-When showing the final render dialog, allow specifying where it came from: the toolbar or the render sequence button.
-Refactor all preview rendering code out into its own class hierarchy with overrides for the main window and the final render dialog.
-Remove all preview render cancelling functions, they are now built into the new class hierarchy and a new render will not start until the previous one is stopped.
-Add two new function ConstrainLow() and ConstrainHigh() which wrap constraining two min/max spinboxes to each others' values.
-Add a bool to FractoriumEmberControllerBase::CopyEmberFile() to specify whether to copy the main file or the sequence file. This is somewhat of a hack and was done in a rush.
-Add a bool to FractoriumEmberControllerBase::SetEmberFile() to specify whether to move the file rather than copy. This is used in FinalRenderEmberController and improves efficiency.
-Add wrapper functions for variations filter dialog settings.
