+	dropped the name mapping to Windows font names.
+	- PostScript output had an extraneous '%' character on the first line,
+	which would cause printing to fail.
+	- Text handling, during both sizing and layout, incorrectly handled
+	empty lines such as label="\nabc".
+	- HTML-like tables had been changed to use too much vertical space,
+	to possibly use the wrong font in calculating the height of a line,
+	and to use the wrong offset when moving the baseline from one line to
+	the next.
+November 27, 2006
+	- release 2.10
+	- dot - New pango+cairo renderer plugin (was in separate graphviz-cairo tree).
+	  -- -Tpng now uses cairo   (-Tpng:gd for old gd based renderer)
+	  -- -Tpdf now available
+	  -- -Tps:cairo now available (-Tps is a direct ps renderer not based on cairo)
+	  -- -Tsvg:cairo now available (-Tsvg is a direct svg renderer not based on cairo)

+	  -- -Tgtk now available -- eventually to provide a graph editing capability - not fully working
+	  -- -Tswf "Flash" now available using the ming library. Currently has incomplete font support and not yet in Fedora rpms because ming not yet available as rpm.
+	- remove hard gd dependencies from dot.  gd renderers now provided
+	  as optional plugin.   Deprecated, but required for -Tjpg, -Tgif and -Tvrml.
+	- gvpr - Add kindOf function, plus functions to set and get default values
+	- dot - Implement esep attribute to allow graph to specify room
+	around nodes for spline routing.
+	- neato - add vpsc library and DIGCOLA
+	- neato - add IPSEPCOLA additions from Tim Dwyer
+	- move: -Tps, -Tfig, -Tsvg, -Timap/ismap/cmap/cmapx, -Tdot/xdot,
+	from codegens to a "core" plugin.
+	- dot - new usershape plugin mechanism potentially supporting
+	  a wider range of input shape format -> output format combinations.
+	display on changes
+	- Fixes for builds on Mac OS/X
+	- dot - new -O switch to automatically generate output file
+	names based on the input filename and the -T value.
+	 e.g.  "dot -Tpng -O *.dot"   
+	Also works for case of multiple graphs in a single input file.
+	- add support for "Brewer" color nameset
+	- move reusable .so libraries to $PREFIX/lib per frequent request
+	from Debian community.   Plugin .so's remain in $PREFIX/lib/graphviz.
+	- Fix bugs 882 884 886 896 902 905 906 911 918 919 933 936 938 940

+
+February 3, 2006
+	- release 2.8
+	- (POTENTIAL INCOMPATIBILITY) The default input scaling, in the
+	absence of a "-s" switch, has been changed from inches to points.
+	The new behavior of "neato" is equivalent to "neato -s72".
+	The old behavior can be restored with "neato -s1".
+	The purpose of this change is to avoid a Frequently-Made-Mistake
+	when using "neato -n" to process a previously generated layout.
+	Previously it was necessary to use "neato -n -s72", but with this
+	change the default matches dot's output and the "-s72" is not required.
+	- Added pseudo layout engines: "dot -Knop" and dot -Knop1" equivalent
+	to "neato -n"
+	- Added pseodo layout engine: "dot -Knop2" equivalent to "neato -n2"
+	- Add support for color namespaces; add Brewer color data
+	- Add support for simulated duplex edges using parallel edges:
+	head arrow takes first color, tail arrow takes second color.
+	- source code management moved back to CVS until GIT matures a bit more
+	- distribute separe rpms for binares of language bindings : 
+	- Add a small pad region around graph renderings to allow for finite
+	penwidths at the drawing edges
+	- Add protonode(g) and E=protoedge(g) functions to simplify
+	language bindings.
+	- Add special purpose code to deal with html labels from language
+	bindings.
+	- Various portability fixes for: HPUX, Mac OS/X, Cygwin, Windows.
+	- Fix bugs 784, 786, 787, 788, 789, 790, 791, 793, 795, 796, 798, 799,

+April 27, 2001: graphviz-1.7.6
+
+    NEW FEATURES
+
+    Added a collection of graph processing tools:
+
+    acyclic : a filter that takes a directed graph as input
+    and outputs a copy of the graph with sufficient edges
+    reversed to make the graph acyclic.
+
+    ccomps : decomposes graphs into their connected components,
+    printing the components to standard output.
+
+    colorize : is a filter that sets node colors from initial
+    seed values. Colors flow along edges from tail to head.
+
+    gc : a graph analogue to wc in that it prints to standard
+    output the number of nodes, edges, connected components or
+    clusters contained in the input files.
+
+    gpr : a graph stream editor inspired by awk. It copies
+    input graphs to its output, possibly transforming their
+    structure and attributes, creating new graphs, or
+    printing arbitrary information.
+
+    nop : reads a stream of graphs and prints each in
+    pretty-printed (canonical) format on stdout.
+
+    sccmap : decomposes digraphs into strongly connected components
+    and an auxiliary map of the relationship between components.
+
+    tred : computes the transitive reduction of directed graphs,
+    and prints the resulting graphs to standard output. This
+    removes edges implied by transitivity.
+
+    unflatten : is a preprocessor to dot that is used to improve
+    the aspect ratio of graphs having many leaves or disconnected
+    nodes. The usual layout for such a graph is generally very
+    wide or tall. unflatten inserts invisible edges or adjusts
+    the minlen on edges to improve layout compaction.
+
+
+    FIXES
+
+    Add FAQ
+
+    Change PNG default background color from transparent to white
+    because of the difficulty some viewers have with transparency.

+    Fix broken support for specific capitalized fontnames
+    (Times Helvetica Arial Courier) 
+

+
+    Some bitmap font scaling fixes - we're still not happy with
+    bitmap font scaling as some labels still exceed the area
+    allocated by the layout engines.
+
+    Some -Timap fixes for mouse sensitive graphs on web pages
+
+    Some cluster layout fixes
+
+    Fix for [rankdir=LR] problems when using neato layout engine
