632 - added "connector" to __all__
636 - separate texter out of the axispainter
637 - axis/partitioner/texter/painter/axispos redesign & interfaces
638 - tick.text is renamed to tick.label
639 - ticks and labels are renamed to tickpos/tickdist and labelpos/labeldist in partitioning
640 - ticks can be used in the part to mix a partitioner with some manual ticks
641 -> manualpart and the mix technique is not needed anymore
642 (both things are still available and working, but they will be removed in the future)
643 - _ensurefrac is implemented inside the frac constructor now; initialization is possible by:
644 - a (enum, denom) tuple now (previously there were two arguments)
645 - a string (as before via _ensurefrac)
646 - exponential strings are allowed as well (e.g. "1e10" etc.)
647 - a float (precision is determined by floatprecision -- the number of decimal places)
652 - reset() method for the texrunner
653 - automatic restart of a TeX instance with the same preamble (preamble changes are not possible)
654 - texmessage.loadfd for accepting font description loading
655 - don't bail out on width_index == 0, but mark character invalid instead
657 - support for specials; pyxgraphics flag
658 - support psfonts.map: font names, font encodings
659 - bugfix \def\ProcessPyXBox -> \long\def\ProcessPyXBox
660 - improved lfs handling
662 - full documentation via doc strings
664 - some preliminary version
666 - multiple radii (up to two per point) and softnesses
667 - ensurecenter added --- do we always force the creation of a center?
669 - lentopar methods added including some tests
671 - new parameter bbox allows to override the bounding box of the eps file
675 - derive TFMError and DVIError correctly from exceptions.Exception
676 - close files and pipes, if they are no longer used (thanks to Marcus Mendenhall)
677 - remove DeprecationWarning in Python 2.3 (thanks to Marcus Mendenhall)
679 - correct rounding algorithm (Michael Schindler)
681 - refer to the graphs texrunner instead of the defaulttexrunner (cf. #728209)
682 - rounding towards zero bugfix in autolinpart
683 - log axis range rating bugfix
685 - addarg bugs (#738724)
687 - fix mixing up of height and width in scale calculation
688 - and various other fixer here and there
692 - fix bug in dvi rule code where width was height
693 - fix preamble attribute checking bug
694 - fix texmessage.load pattern search instead of pattern match bug
695 - renamed vbox to parbox (was done in 0.3 partially only)
697 - allow for tuples in arguments of the data class
698 - convenience: exchanged order of named parameters in data.data
700 - convenience: allow for part=None in _axis (base of linaxis and logaxis)
702 - added a latex example (requested)
703 - added a attributechange example (requested)
704 - added back the integral example (requested; prior PyX 0.3 it was part of the user manual)
705 - small change in vector example (allow for the access to the texrunner)
706 - examples included in source distribution
708 - correct arrow template calculation for very short paths
712 - new easy to use example generation (will hopefully lead to nice examples)
714 - new module for handling of convex polygons (taken out of the graph module)
716 - new module containing a collection of helper functions (taken out of the graph module)
717 - moved the attrlist into helper -- as plain functions; attrlist becomes obsolete
719 - new module: a new and preferable integration of TeX/LaTeX
721 - strip glyphs from pfa/pfb-fonts
722 - there is a C implementation taken from pdftex
723 - fallback solution via an external program (pfb2pfa)
725 - (partial) C binding to libkpathsea
726 - fallback solution via an external program (kpsewhich)
728 - removed some code duplication (various axis painters)
729 - use text module instead of the obsolete tex module
730 - allow for tailing zeros of automatic generated labels
731 - allow for missing data in bar graphs -> skipmissing parameter
732 - remove the support for variables given as keyword arguments in data constructor
733 - use context instead of extern for extern variables and functions
734 - graph keys; titles in data/function/etc.
736 - new classes for visual and width lengths, aliases for user length (u_pt = pt)
737 - all length classes have now by default a quantifier 1 (instead of 0), such that,
738 for instance, 5*unit.t_cm() == unit.t_cm(5)
739 - default_unit now has to be set via unit.set. For instance: unit.set(defaultunit="m").
740 - convert_to is now an internal function, which moreover does not longer accept tuples or lists
742 - new class _bbox (the former bbox) which accepts points in the constructor. This is used
743 for internal purposes.
744 - the bbox constructor now accepts user lengths in the constructor.
745 - new methods height, width, top, bottom, left, right
746 - ll & ur ???, what about ul and lr -> ugly!
747 - enlarge (was enhance) now allows selective enlargement to the left, bottom, right and top
748 - output HiResBoundingBox
749 - never reduce bbox upon output
751 - new constructor signature, more in line with rest of PyX:
752 epsfile(x, y, filename, **additional_args)
754 - removed additional column support in addcolumn; removed _addcolumn
755 - line reduction for datafile like the every parameter in gnuplot
757 - new way of PS prolog generation that writes only necessary parts
758 - added support for patterns
759 - canvas.insert() now supports arguments
760 - bbox of canvas can be specified in writetofile command explicitely
761 - writetofile does not return self anymore
762 - arrow template now uses intersection with circle to get size right
763 (as per a suggestion by Michael Schindler)
766 - changed the handling of extern functions and all variables
768 - gradient renamed to palette
770 - problem with sizefile on windows (tex module)
771 - allow for strings in graphxy's width and height; allow for width only (graph module)
772 - disable rating for labelattrs equals None (graph module)
773 - defaultstyle selection, when a list of data is provided to the plot function (graph module)
774 - traverse when adding functions as arguments of operators (mathtree module)
775 - allow for extern functions in addcolumn (data module)
776 - just one common place for the version number
777 - fix incorrect exception name MathError (path module)
778 - prevent double return of intersections for closed sub paths
783 - allow division of length by numbers
785 - new transformation: slant
786 - renamed all trafo methods to use the participle (i.e translate->translated)
787 - the name of all trafo subclasses are verbs (i.e. translation->translate)
789 - mark class renamed to symbol
790 - (text-)box distance measurement
791 - moved axis partitioning to axis and axis painter
792 - automatic axis partitioning (now officially: general cleanup, distance measurement, documentation)
794 - baraxis, baraxispainter, and bar style
796 - previously named datafile module
797 - class "_datafile" renamed to class "data"
798 - class sectionfile added
801 - extern variables and functions (support in graph.function, graph.paramfunction and data.data)
804 - deferred to Version 0.3
805 - running TeX "on the fly" is basically implemented
807 - transformation bug (#624068, trafo module)
808 - canvas transformations (canvas module???)
809 - textbox alignment (graph module)
810 - return linewidth upon calculation with linewidths (unit module)
811 - allow column number variables with several digits
813 - british and american spellings (color module, graph module)
814 - small logo modifications
