656 (as it was in parts of the documentation already)
657 - changeable-gridattrs-become-None-bug fixed
658 - graph style cutting outside lines (double-)fixed
662 - fixes missing install of the graph and axis directories introduced in 0.6
663 - some minor updates to the faq
668 - reorganisation of the graph structure finished (there might be some
669 small pending issues, but the basic restructuring is done with this release):
670 - graph splitted into several modules in pyx/graph and pyx/graph/axis
671 - painters are using the new attribute scheme including changeable
673 - graph styles rewrite
675 - axis zeropath feature has been removed
676 - mergelabels removed; linpart doesn't have a label argument anymore
677 - names and texts removed from baraxis
678 - iteration on graph style, when it is used several times in the same graph
679 - symbols + lines -> symbollines; symbols do not allow setting lineattrs,
680 and lines not symbolattrs
681 - manual line clipping (do not include unneeded line segments when the
682 axis range is set manually etc.)
683 - automatic file key titles
684 - graph.data now also includes the old data module
685 - data.list adds (by default) a line number like data.file
686 (thus regular columns are counted from 1)

689 a list of points and can thus be much more efficient
690 - internal methods return coordinates in pts
691 - arclentoparam returns only parameters not total length
692 - added path.arclength_pt, path.at_pt, path.begin_pt, path.end_pt (and
693 correspondingly for normpath)
694 - complete refactoring of the normpath class: normpaths now consist of
695 normsubpaths which themselves consist of normlines and normcurves This is
696 much more convenient for any routines working with normpaths.
697 - reversing of closed sub paths does not change the first point of the sub
699 - renamed: arclength -> arclen
700 - renamed: lentopar -> arclentoparam
701 - renamed: glue -> joined
702 - normpath now supports join, the in-place version of joined
703 - path and normpath method raise exception instead of returning None
704 when parameter is out of range

706 constructor and no longer in arguments of path and normpath methods

708 - path and normpath methods which accept parameter value param now
709 alternatively accept an arc length
713 - arrow heads are no longer stroked (as suggested by Magnus Lie Hetland)
715 - writeEPSfile deprecates writetofile
716 - internally, write methods are renamed in outputPS
717 - canvas constructor no longer accepts variable argument list but
718 expects a list of attrs as first argument (defaulting to []) and
719 a texrunner as second argument (defaulting to text.defaulttexrunner)
720 - set, draw, stroke and fill no longer return self, i.e., the canvas, but None
722 - added inplace add (__iadd__), enlarge and transform methods
723 - callers use inplace add where possible now (yielding a considerable
725 - "undefined" corners of bounding boxes are no longer supported which makes
726 the bounding box operations much more efficient.
