7 ## [Unreleased (6.0.2)]
11 - Using `aspect` with a custom value in the `packmode` attribute is no longer
13 - Smyrna bounding box computation has been corrected. There was a regression in
14 4.0.0 that resulted in a degenerate bounding box being computed for any input
15 graph. See #2279 for details.
16 - Smyrna warnings about the `on_attrRB0_clicked` and `on_attrSearchBtn_clicked`
17 handlers being not found have been fixed and the buttons to which they are
18 wired should be functional again. This was a regression in 2.50.0 See #2279
20 - Smyrna warnings about the `mAttributesSlot` handler being not found have been
21 fixed and the button to which it is wired should be functional again. This was
22 a regression in 2.49.2 See #2279 for details.

179 struct are now C99 `bool`s instead of Graphviz-specific `boolean`s.

194 - **Breaking**: `pccomps` now takes a C99 `bool` instead of a `boolean` output

1033 - Using system version of libgd if gd-2.0.34 or later. (Fedora 7 and 8 distros)
1034 internal copy of gd updated to gd-2.0.35.
1035 - Updated GVGUI viewer for Windows
1036 - Windows build process now uses GNU autoconf and UWIN

1038 line, polyline, orthogonal, spline
1039 - Added -Tvml support
1042 - Bug fix release for 2.10
1043 - The gd plugin for font handlers was not being used at all if the build
1044 did not use fontconfig, e.g., on Windows. In addition, the code had
1045 dropped the name mapping to Windows font names.
1046 - PostScript output had an extraneous '%' character on the first line,
1047 which would cause printing to fail.
1048 - Text handling, during both sizing and layout, incorrectly handled
1049 empty lines such as label="\nabc".
1050 - HTML-like tables had been changed to use too much vertical space,
1051 to possibly use the wrong font in calculating the height of a line,
1052 and to use the wrong offset when moving the baseline from one line to
1056 - dot - New pango+cairo renderer plugin (was in separate graphviz-cairo tree).
1057 -- -Tpng now uses cairo (-Tpng:gd for old gd based renderer)
1058 -- -Tpdf now available
1059 -- -Tps:cairo now available (-Tps is a direct ps renderer not based on cairo)
1060 -- -Tsvg:cairo now available (-Tsvg is a direct svg renderer not based on cairo)
1061 -- -Txlib now available -- "dot -Tx11 foo.dot" watches foo.dot with inotify and updates
1062 -- -Tgtk now available -- eventually to provide a graph editing capability - not fully working
1063 -- -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.
1064 - remove hard gd dependencies from dot. gd renderers now provided
1065 as optional plugin. Deprecated, but required for -Tjpg, -Tgif and -Tvrml.
1066 - gvpr - Add kindOf function, plus functions to set and get default values
1067 - dot - Implement esep attribute to allow graph to specify room
1068 around nodes for spline routing.

1070 - neato - add IPSEPCOLA additions from Tim Dwyer
1071 - move: -Tps, -Tfig, -Tsvg, -Timap/ismap/cmap/cmapx, -Tdot/xdot,
1072 from codegens to a "core" plugin.
1073 - dot - new usershape plugin mechanism potentially supporting
1074 a wider range of input shape format -> output format combinations.
1076 - Fixes for builds on Mac OS/X
1077 - dot - new -O switch to automatically generate output file
1078 names based on the input filename and the -T value.
1079 e.g. "dot -Tpng -O *.dot"
1080 Also works for case of multiple graphs in a single input file.
1081 - add support for "Brewer" color nameset
1082 - move reusable .so libraries to $PREFIX/lib per frequent request
1083 from Debian community. Plugin .so's remain in $PREFIX/lib/graphviz.

1086 1018 1025 1030 1034 1035 1039 1040 debian#37300
1090 - (POTENTIAL INCOMPATIBILITY) The default input scaling, in the
1091 absence of a "-s" switch, has been changed from inches to points.
1092 The new behavior of "neato" is equivalent to "neato -s72".
1093 The old behavior can be restored with "neato -s1".
1094 The purpose of this change is to avoid a Frequently-Made-Mistake
1095 when using "neato -n" to process a previously generated layout.
1096 Previously it was necessary to use "neato -n -s72", but with this
1097 change the default matches dot's output and the "-s72" is not required.
1098 - Added pseudo layout engines: "dot -Knop" and dot -Knop1" equivalent
1100 - Added pseodo layout engine: "dot -Knop2" equivalent to "neato -n2"
1101 - Add support for color namespaces; add Brewer color data

1105 - distribute separe rpms for binares of language bindings :
1106 - Add a small pad region around graph renderings to allow for finite
1107 penwidths at the drawing edges

1110 - Add special purpose code to deal with html labels from language

1120 - experimentally moved source code management from CVS to GIT
1121 - added iterator functions to script bindings

1188 NB. the fontname attribute in graphs is now a font pattern

1707 April 27, 2001: graphviz-1.7.6
1711 Added a collection of graph processing tools:
1713 acyclic : a filter that takes a directed graph as input
1714 and outputs a copy of the graph with sufficient edges
1715 reversed to make the graph acyclic.
1717 ccomps : decomposes graphs into their connected components,
1718 printing the components to standard output.
1720 colorize : is a filter that sets node colors from initial
1721 seed values. Colors flow along edges from tail to head.
1723 gc : a graph analogue to wc in that it prints to standard
1724 output the number of nodes, edges, connected components or
1725 clusters contained in the input files.
1727 gpr : a graph stream editor inspired by awk. It copies
1728 input graphs to its output, possibly transforming their
1729 structure and attributes, creating new graphs, or
1730 printing arbitrary information.
1732 nop : reads a stream of graphs and prints each in
1733 pretty-printed (canonical) format on stdout.
1735 sccmap : decomposes digraphs into strongly connected components
1736 and an auxiliary map of the relationship between components.
1738 tred : computes the transitive reduction of directed graphs,
1739 and prints the resulting graphs to standard output. This
1740 removes edges implied by transitivity.
1742 unflatten : is a preprocessor to dot that is used to improve
1743 the aspect ratio of graphs having many leaves or disconnected
1744 nodes. The usual layout for such a graph is generally very
1745 wide or tall. unflatten inserts invisible edges or adjusts
1746 the minlen on edges to improve layout compaction.
1753 Change PNG default background color from transparent to white
1754 because of the difficulty some viewers have with transparency.
1756 Add support for [color=transparent]
1758 Fix broken support for specific capitalized fontnames
1759 (Times Helvetica Arial Courier)
1761 Fix broken support for DOTFONTPATH
1763 Some bitmap font scaling fixes - we're still not happy with
1764 bitmap font scaling as some labels still exceed the area
1765 allocated by the layout engines.
1767 Some -Timap fixes for mouse sensitive graphs on web pages
1769 Some cluster layout fixes
1771 Fix for [rankdir=LR] problems when using neato layout engine
