636 - tick.text is renamed to tick.label
637 - ticks and labels are renamed to tickpos/tickdist and labelpos/labeldist in partitioning

639 -> manualpart and the mix technique is not needed anymore
640 (both things are still available and working, but they will be removed in the future)
641 - _ensurefrac is implemented inside the frac constructor now; initialization is possible by:
642 - a (enum, denom) tuple now (previously there were two arguments)
643 - a string (as before via _ensurefrac)

704 - examples included in source distribution
706 - correct arrow template calculation for very short paths
710 - new easy to use example generation (will hopefully lead to nice examples)
712 - new module for handling of convex polygons (taken out of the graph module)
714 - new module containing a collection of helper functions (taken out of the graph module)
715 - moved the attrlist into helper -- as plain functions; attrlist becomes obsolete
717 - new module: a new and preferable integration of TeX/LaTeX
719 - strip glyphs from pfa/pfb-fonts
720 - there is a C implementation taken from pdftex
721 - fallback solution via an external program (pfb2pfa)
723 - (partial) C binding to libkpathsea
724 - fallback solution via an external program (kpsewhich)
726 - removed some code duplication (various axis painters)
727 - use text module instead of the obsolete tex module
728 - allow for tailing zeros of automatic generated labels
729 - allow for missing data in bar graphs -> skipmissing parameter
730 - remove the support for variables given as keyword arguments in data constructor
731 - use context instead of extern for extern variables and functions
732 - graph keys; titles in data/function/etc.
734 - new classes for visual and width lengths, aliases for user length (u_pt = pt)
735 - all length classes have now by default a quantifier 1 (instead of 0), such that,
736 for instance, 5*unit.t_cm() == unit.t_cm(5)
737 - default_unit now has to be set via unit.set. For instance: unit.set(defaultunit="m").
738 - convert_to is now an internal function, which moreover does not longer accept tuples or lists
740 - new class _bbox (the former bbox) which accepts points in the constructor. This is used
741 for internal purposes.
742 - the bbox constructor now accepts user lengths in the constructor.
743 - new methods height, width, top, bottom, left, right
744 - ll & ur ???, what about ul and lr -> ugly!

747 - never reduce bbox upon output
749 - new constructor signature, more in line with rest of PyX:
750 epsfile(x, y, filename, **additional_args)
752 - removed additional column support in addcolumn; removed _addcolumn
753 - line reduction for datafile like the every parameter in gnuplot
755 - new way of PS prolog generation that writes only necessary parts
756 - added support for patterns
757 - canvas.insert() now supports arguments
758 - bbox of canvas can be specified in writetofile command explicitely
759 - writetofile does not return self anymore

761 (as per a suggestion by Michael Schindler)
764 - changed the handling of extern functions and all variables
766 - gradient renamed to palette
768 - problem with sizefile on windows (tex module)
769 - allow for strings in graphxy's width and height; allow for width only (graph module)
770 - disable rating for labelattrs equals None (graph module)
771 - defaultstyle selection, when a list of data is provided to the plot function (graph module)
772 - traverse when adding functions as arguments of operators (mathtree module)
773 - allow for extern functions in addcolumn (data module)
774 - just one common place for the version number
775 - fix incorrect exception name MathError (path module)
776 - prevent double return of intersections for closed sub paths
781 - allow division of length by numbers
783 - new transformation: slant
784 - renamed all trafo methods to use the participle (i.e translate->translated)
785 - the name of all trafo subclasses are verbs (i.e. translation->translate)
787 - mark class renamed to symbol
788 - (text-)box distance measurement
789 - moved axis partitioning to axis and axis painter
790 - automatic axis partitioning (now officially: general cleanup, distance measurement, documentation)
792 - baraxis, baraxispainter, and bar style
794 - previously named datafile module
795 - class "_datafile" renamed to class "data"

803 - running TeX "on the fly" is basically implemented
805 - transformation bug (#624068, trafo module)
806 - canvas transformations (canvas module???)
807 - textbox alignment (graph module)
808 - return linewidth upon calculation with linewidths (unit module)
809 - allow column number variables with several digits
811 - british and american spellings (color module, graph module)
812 - small logo modifications
