+
+ 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.

+
+ 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.
+
+ Add support for [color=transparent]
+
+ Fix broken support for specific capitalized fontnames
+ (Times Helvetica Arial Courier)
+
+ Fix broken support for DOTFONTPATH
+
+ 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
+
+ Some neato layout fixes
+
+ Updates to unix.dot
