-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
-Move build system to Visual Studio 2015 and Qt 5.6.
-SSE used during addition of points to the histogram.
-Remove last remnants of old flam3 C code and replace with C++.
-Remove unused code involving tbb::task_group.
-Make settings object a global shared_ptr singleton, so it doesn't have to be passed around.
-Remove the option --intpalette to format the palette in the xml as ints. If they are not hex formatted, then they should always be float. This option was pointless.
-Cleanup some options text for the command line programs.
-Allow for dragging around flames in the library tab. This is useful for setting up the order of an animation.
-Make the opening of large files in Fractorium much more efficient when not-appending.
-Make the opening of large files in all EmberRender and EmberAnimate more efficient.
-Better error reporting when opening files.
--Bug fixes
-Get rid of leftover artifacts that would appear on preview thumbnails when either switching SP/DP or re-rendering previews.
-Filename extension was not being appended on Linux when saving as Xml, thus making it impossible to drag that file back in becase drop is filtered on extension.
--Code changes
-Move GCC compiler spec to C++14. Building with 5.3 now on linux.
-Use inline member data initializers.
-Make a #define for static for use in Utils.h to make things a little cleaner.
-Make various functions able to take arbitrary collections as their parameters rather than just vectors.
-Make library collection a list rather than vector. This alleviates the need to re-sync pointers whenever the collection changes.
-Subclass QTreeWidget for the library tree. Two new files added for this.
-Remove all usage of #ifdef ROW_ONLY_DE in DEOpenCLKernelCreator, it was never used.
-Add move constructor and assignment operator to EmberFile.
-Add the ability to use a pointer to outside memory in the renderer for the vector of Ember<T>.
-Make a lot more functions const where they should be.
-Add variations changes to the list of functionality that can be applied to all xforms using the Select tab.
-Allow for graphical affine adjustments to apply to multiple selected xforms.
-Slight optimization of the pie variation.
-Undo state is only saved when the render completes and the mouse buttons are released. This helps avoid intermediate steps for quickly completing renders while dragging.
-Add some keyboard shortcuts for toolbar and menu items.
-Make info tab tree always expanded.
--Bug fixes
-Make precalcs for all hypertile variations safer by using Zeps() for denominators.
-Changing the current xform with more than one selected would set all xform's color index value that of the current one.
-Use hard found palette path information for randoms as well.
-OpenCL build and assignment errors for Z value in epispiral variation.
-Unitialized local variables in hexaplay3D, crob, pRose3D.
--Code changes
-Change static member variables from m_ to s_.
-Get rid of excessive endl and replace with "\n".
-Remove old IMAGEGL2D define from before Nvidia supported OpenCL 1.2.
-Remove old CriticalSection code and use std::recursive_mutex.
-Make Affine2D Rotate() and RotateTrans() take radians instead of angles.
-More C++11 work.
-General cleanup.
