634 - axis/partitioner/texter/painter/axispos redesign & interfaces
635 - tick.text is renamed to tick.label
636 - ticks and labels are renamed to tickpos/tickdist and labelpos/labeldist in partitioning
637 - ticks can be used in the part to mix a partitioner with some manual ticks
638 -> manualpart and the mix technique is not needed anymore
639 (both things are still available and working, but they will be removed in the future)
640 - _ensurefrac is implemented inside the frac constructor now; initialization is possible by:
641 - a (enum, denom) tuple now (previously there were two arguments)
642 - a string (as before via _ensurefrac)
643 - exponential strings are allowed as well (e.g. "1e10" etc.)
644 - a float (precision is determined by floatprecision -- the number of decimal places)
649 - reset() method for the texrunner
650 - automatic restart of a TeX instance with the same preamble (preamble changes are not possible)
651 - texmessage.loadfd for accepting font description loading
652 - don't bail out on width_index == 0, but mark character invalid instead
654 - support for specials; pyxgraphics flag
655 - support psfonts.map: font names, font encodings
656 - bugfix \def\ProcessPyXBox -> \long\def\ProcessPyXBox
657 - improved lfs handling
659 - full documentation via doc strings
661 - some preliminary version
663 - multiple radii (up to two per point) and softnesses
664 - ensurecenter added --- do we always force the creation of a center?
666 - lentopar methods added including some tests
668 - new parameter bbox allows to override the bounding box of the eps file
672 - derive TFMError and DVIError correctly from exceptions.Exception

674 - remove DeprecationWarning in Python 2.3 (thanks to Marcus Mendenhall)
676 - correct rounding algorithm (Michael Schindler)
678 - refer to the graphs texrunner instead of the defaulttexrunner (cf. #728209)
679 - rounding towards zero bugfix in autolinpart
680 - log axis range rating bugfix
682 - addarg bugs (#738724)
684 - fix mixing up of height and width in scale calculation
685 - and various other fixer here and there
689 - fix bug in dvi rule code where width was height
690 - fix preamble attribute checking bug
691 - fix texmessage.load pattern search instead of pattern match bug
692 - renamed vbox to parbox (was done in 0.3 partially only)
694 - allow for tuples in arguments of the data class
695 - convenience: exchanged order of named parameters in data.data
697 - convenience: allow for part=None in _axis (base of linaxis and logaxis)
699 - added a latex example (requested)
700 - added a attributechange example (requested)

702 - small change in vector example (allow for the access to the texrunner)
703 - examples included in source distribution
705 - correct arrow template calculation for very short paths
709 - new easy to use example generation (will hopefully lead to nice examples)
711 - new module for handling of convex polygons (taken out of the graph module)
713 - new module containing a collection of helper functions (taken out of the graph module)
714 - moved the attrlist into helper -- as plain functions; attrlist becomes obsolete
716 - new module: a new and preferable integration of TeX/LaTeX
718 - strip glyphs from pfa/pfb-fonts
719 - there is a C implementation taken from pdftex
720 - fallback solution via an external program (pfb2pfa)
722 - (partial) C binding to libkpathsea
723 - fallback solution via an external program (kpsewhich)
725 - removed some code duplication (various axis painters)
726 - use text module instead of the obsolete tex module
727 - allow for tailing zeros of automatic generated labels
728 - allow for missing data in bar graphs -> skipmissing parameter
729 - remove the support for variables given as keyword arguments in data constructor
730 - use context instead of extern for extern variables and functions
731 - graph keys; titles in data/function/etc.
733 - new classes for visual and width lengths, aliases for user length (u_pt = pt)
734 - all length classes have now by default a quantifier 1 (instead of 0), such that,
735 for instance, 5*unit.t_cm() == unit.t_cm(5)
736 - default_unit now has to be set via unit.set. For instance: unit.set(defaultunit="m").
737 - convert_to is now an internal function, which moreover does not longer accept tuples or lists
739 - new class _bbox (the former bbox) which accepts points in the constructor. This is used
740 for internal purposes.
741 - the bbox constructor now accepts user lengths in the constructor.
742 - new methods height, width, top, bottom, left, right
743 - ll & ur ???, what about ul and lr -> ugly!
744 - enlarge (was enhance) now allows selective enlargement to the left, bottom, right and top
745 - output HiResBoundingBox
746 - never reduce bbox upon output
748 - new constructor signature, more in line with rest of PyX:
749 epsfile(x, y, filename, **additional_args)
751 - removed additional column support in addcolumn; removed _addcolumn
752 - line reduction for datafile like the every parameter in gnuplot
754 - new way of PS prolog generation that writes only necessary parts
755 - added support for patterns
756 - canvas.insert() now supports arguments
757 - bbox of canvas can be specified in writetofile command explicitely
758 - writetofile does not return self anymore

760 (as per a suggestion by Michael Schindler)
763 - changed the handling of extern functions and all variables
765 - gradient renamed to palette
767 - problem with sizefile on windows (tex module)
768 - allow for strings in graphxy's width and height; allow for width only (graph module)
769 - disable rating for labelattrs equals None (graph module)
770 - defaultstyle selection, when a list of data is provided to the plot function (graph module)
771 - traverse when adding functions as arguments of operators (mathtree module)
772 - allow for extern functions in addcolumn (data module)
773 - just one common place for the version number
774 - fix incorrect exception name MathError (path module)
775 - prevent double return of intersections for closed sub paths
780 - allow division of length by numbers
782 - new transformation: slant
783 - renamed all trafo methods to use the participle (i.e translate->translated)
784 - the name of all trafo subclasses are verbs (i.e. translation->translate)
786 - mark class renamed to symbol
787 - (text-)box distance measurement
788 - moved axis partitioning to axis and axis painter
789 - automatic axis partitioning (now officially: general cleanup, distance measurement, documentation)
791 - baraxis, baraxispainter, and bar style
793 - previously named datafile module
794 - class "_datafile" renamed to class "data"
795 - class sectionfile added
798 - extern variables and functions (support in graph.function, graph.paramfunction and data.data)
801 - deferred to Version 0.3
802 - running TeX "on the fly" is basically implemented
804 - transformation bug (#624068, trafo module)
805 - canvas transformations (canvas module???)
806 - textbox alignment (graph module)
807 - return linewidth upon calculation with linewidths (unit module)
808 - allow column number variables with several digits
810 - british and american spellings (color module, graph module)
811 - small logo modifications
