- (Qt4 related) keyboard shortcuts rationalized
many removed, ctrl-modifiers dropped
- (Qt4 related) image displays now have a frame around them
- (Qt4 related) Remove non-standard Qt animated PNG support
- evolvotron_match removed
- Platform specific code (e.g number of processors identification)
isolated in libevolvotron/platform_specific.[h|cpp]
and selected by PLATFORM_LINUX or PLATFORM_BSD
(Fink Qt's __DARWIN_X11__ also detected and used to select PLATFORM_BSD).
- Repository migrated to svn
From release 0.5.0:
- Version to 0.5.1
- Replace not often used frontside heating/cooling buttons with autocooling mechanism.
- Separate tabs for info & license on "About" dialog.
- Better formatting of function properties dialog, and also shows XML function tree.
- Dialog with rendering controls
- Multisampling (antialiasing) options
- -a/-j/-s command line options for autocool/jitter/multisample
- evolvotron_render adds -j/-s to control jitter & multisampling
- Option (-E) of separate thread pool (with different nices: -n/-N) for enlargements.
Task totals for each reported separately.
- Enlargement and solo renderings are fragmented into multiple smaller
jobs to better utilize multiprocessor systems.
- Generally better use of ref-counted QImage and QPixmap.
- Middle-mouse drag adjustments flicker less.
From release 0.4.0:
- Version to 0.5.0
- Lists of functions in alphabetic order.
- New FunctionTop always at top level.
- New functions: Frieze groups.
- Constantness of functions more conservative (less overrides) and hopefully less buggy.
- Final colour space transform range more constrained to keep colours sane.
- More sensible mutation of top level spatial transform (less arbitrary shearing).
- Note that above changes mean old saved functions will appear different.
- New mutation parameter: probability of a function's parameters being reset.
- Code clean up:
- More std::auto_ptr, boost::shared_ptr, boost::ptr_vector. Code is now delete free.
- Get rid of hacked static function registration; uses auto-generated register_all_functions.
- Compute threads use QWaitCondition, not polling.
- Default number of threads is number of processors.
- Compute threads run at lower priority.
- -n <niceness> command line option to control compute thread priority.
(NB assumes Linux NPTL's non-Posix compliant behaviour of threads NOT sharing a common nice value;
see "man pthreads" on Linux.)
- About dialog displays number of threads.
- Use precompiled headers (build time 2m45s down to 1m45s).
- code_review script
- Set an icon on various dialogs and main frame.
- Add -D (function debug) massively weighting in favour of FunctionNoiseOneChannel. Useful with -x/-X.
- Believed to fix Debian bug #436231 and gentoo #144160

- Fix broken FunctionGradient.
Replace with GradientOfMagnitude, DivergenceOfMagnitude, Divergence, Curl

- Add not-very-useful .qt-mng image file output format
- Add function stats to Properties dialog
- Add function simplification (more useful for debugging than anything)

- Add pkg/debian .deb builder script (still under development)
- Fix buggy Y rotation matrix
- Eliminate template-tastic Tuple and Matrix classes.
Fix XYZ and Transform to not require them.

- Change default grid to 6x5 (would sooner have fat than thin images)
From release 0.2.0:
- Bump version to 0.2.1
- Display (not compute) priority to higher resolution images
(saves time enlarging low res images unnecessarily)
- Blank images on replacement (above change makes this more necessary)
- Round-robin dispatch of done tasks to displays means redisplay more balanced.
- -x and -X command line options to specify specifc top level function types.
- FunctionKaleidoscope*, FunctionWindmill*, FunctionSeparateZ added.
- More iterative functions also added: FunctionStreak Function*Ring
- Added -f <frames> option to evolvotron_render
- Internals: function framework changed (avoids FunctionNodeUsing::evaluate wrapper), speed improvement ?
- Internals: Type of top-level node can mutate, MutatableImage more sane.
- "Undo" keyboard accelerator works
- Per-image display "Properties" dialog added (placeholder)
From release 0.1.4:
- Bump version to 0.2.0
- Filenames converted to/from QString using Qt's "local8Bit" codec.
- -f option specifies number of frames (default 1, which is the non-animated behaviour of previous versions)
- -r option specifies framerate of full-resolution animation (default 8, about the minimum to look smooth)
- Animations save to multiple files
From release 0.1.3:
- Bump version to 0.1.4
- Function tree growth rate restored to pre-0.1.2 rates
- Both multiscale noise types counted as iterative as originally intended.

into instance-get methods.
From release 0.1.0:

- More functions!
From release 0.0.5:
- Bump version to 0.1.0
- Fix nasty bug in computers where a task could be delivered and deleted while
the compute thread was still setting state in it
(timing related so it never happened with ccmalloc and valgrind).

(also makes adding functions easier)
- Save/load individual functions to XML

- More interesting start up functions
- More functions (e.g rotation and spirals, geometric inverse, iterated fns, fractals...)

- Move Cool/Shield buttons to be adjacent (commonly used together).
- "is_constant" query method used to eliminate boring constant images.
- x&y co-ordinate alignment fixed (not something users would notice)
- Spawn warped made less messy: just generates translate/scale/rotate... no shearing.
