641 - full documentation via doc strings
643 - some preliminary version
645 - multiple radii (up to two per point) and softnesses
646 - ensurecenter added --- do we always force the creation of a center?

661 - rounding towards zero bugfix in autolinpart
662 - log axis range rating bugfix
664 - addarg bugs (#738724)
666 - fix mixing up of height and width in scale calculation
667 - and various other fixer here and there
671 - fix bug in dvi rule code where width was height
672 - fix preamble attribute checking bug
673 - fix texmessage.load pattern search instead of pattern match bug
674 - renamed vbox to parbox (was done in 0.3 partially only)
676 - allow for tuples in arguments of the data class
677 - convenience: exchanged order of named parameters in data.data
679 - convenience: allow for part=None in _axis (base of linaxis and logaxis)
681 - added a latex example (requested)
682 - added a attributechange example (requested)
683 - added back the integral example (requested; prior PyX 0.3 it was part of the user manual)
684 - small change in vector example (allow for the access to the texrunner)
685 - examples included in source distribution
687 - correct arrow template calculation for very short paths
691 - new easy to use example generation (will hopefully lead to nice examples)
693 - new module for handling of convex polygons (taken out of the graph module)
695 - new module containing a collection of helper functions (taken out of the graph module)
696 - moved the attrlist into helper -- as plain functions; attrlist becomes obsolete
698 - new module: a new and preferable integration of TeX/LaTeX
700 - strip glyphs from pfa/pfb-fonts
701 - there is a C implementation taken from pdftex
702 - fallback solution via an external program (pfb2pfa)
704 - (partial) C binding to libkpathsea
705 - fallback solution via an external program (kpsewhich)
707 - removed some code duplication (various axis painters)
708 - use text module instead of the obsolete tex module
709 - allow for tailing zeros of automatic generated labels
710 - allow for missing data in bar graphs -> skipmissing parameter
711 - remove the support for variables given as keyword arguments in data constructor
712 - use context instead of extern for extern variables and functions
713 - graph keys; titles in data/function/etc.
715 - new classes for visual and width lengths, aliases for user length (u_pt = pt)
716 - all length classes have now by default a quantifier 1 (instead of 0), such that,
717 for instance, 5*unit.t_cm() == unit.t_cm(5)
718 - default_unit now has to be set via unit.set. For instance: unit.set(defaultunit="m").
719 - convert_to is now an internal function, which moreover does not longer accept tuples or lists
721 - new class _bbox (the former bbox) which accepts points in the constructor. This is used
722 for internal purposes.
723 - the bbox constructor now accepts user lengths in the constructor.
724 - new methods height, width, top, bottom, left, right
725 - ll & ur ???, what about ul and lr -> ugly!
726 - enlarge (was enhance) now allows selective enlargement to the left, bottom, right and top
727 - output HiResBoundingBox
728 - never reduce bbox upon output
730 - new constructor signature, more in line with rest of PyX:
731 epsfile(x, y, filename, **additional_args)
733 - removed additional column support in addcolumn; removed _addcolumn
734 - line reduction for datafile like the every parameter in gnuplot
736 - new way of PS prolog generation that writes only necessary parts
737 - added support for patterns
738 - canvas.insert() now supports arguments
739 - bbox of canvas can be specified in writetofile command explicitely
740 - writetofile does not return self anymore
741 - arrow template now uses intersection with circle to get size right
742 (as per a suggestion by Michael Schindler)
745 - changed the handling of extern functions and all variables
747 - gradient renamed to palette
749 - problem with sizefile on windows (tex module)
750 - allow for strings in graphxy's width and height; allow for width only (graph module)
751 - disable rating for labelattrs equals None (graph module)
752 - defaultstyle selection, when a list of data is provided to the plot function (graph module)
753 - traverse when adding functions as arguments of operators (mathtree module)
754 - allow for extern functions in addcolumn (data module)
755 - just one common place for the version number
756 - fix incorrect exception name MathError (path module)
757 - prevent double return of intersections for closed sub paths
762 - allow division of length by numbers
764 - new transformation: slant
765 - renamed all trafo methods to use the participle (i.e translate->translated)
766 - the name of all trafo subclasses are verbs (i.e. translation->translate)
768 - mark class renamed to symbol
769 - (text-)box distance measurement
770 - moved axis partitioning to axis and axis painter
771 - automatic axis partitioning (now officially: general cleanup, distance measurement, documentation)
773 - baraxis, baraxispainter, and bar style
775 - previously named datafile module
776 - class "_datafile" renamed to class "data"
777 - class sectionfile added
780 - extern variables and functions (support in graph.function, graph.paramfunction and data.data)
783 - deferred to Version 0.3
784 - running TeX "on the fly" is basically implemented
786 - transformation bug (#624068, trafo module)
787 - canvas transformations (canvas module???)
788 - textbox alignment (graph module)
789 - return linewidth upon calculation with linewidths (unit module)
790 - allow column number variables with several digits
792 - british and american spellings (color module, graph module)
793 - small logo modifications
