New features (July 2013)
Graphviz now supports the star node shape and a variation of linear
gradient fill with no gradient (thus, two solid colors) where the
user can specify the proportion using a colorList type for fillcolor.
New Release 2.30 (January-February 2013)
The 2.30 Release marks the switch over from the original Graphviz
graph library to the new cgraph library. If this works as planned,
the user should see no differences. The advantage of the library
is that it is much more flexible for the programmer, with a cleaner
API and support for dynamic data structures. This latter, in addition
to allowing easier mixing of algorithms, has the potential to
greatly reduce memory use in Graphviz.
One side-effect of the new library is a new level ranking algorithm
for dot. This algorithm has fewer constraints, so it is now possible
for a node to be in a cluster and be involved in a rank=same
constraint.
New features (November 2012)
We have provided Graphviz with some additional graphics, which can
be used to provide more semantic information in a graph or enhance
its aesthetics. These include gradient fill for nodes and graphs;
striped and wedged fills, so the amount of each color can be used
to represent some percentage; new node shapes pertinent to the
synthetic biology community (Thanks to Jenny Cheng); and curved
edge routing.
New features (September 2011)
We added lightweight edge labels (xlabel) and tapered edges (as a
style). There was a recent paper by Holten et al about a study of
the readability of various edge styles. We're working on some
examples and documentation. Here are some examples. (We need a
better example for xlabels, because they can float, and aren't
stuck to the upper left of the node.)
New Release 2.28 (Summer 2011)
The 2.28 release of Graphviz incorporates GvMap (formerly GMap, or
"graphs as maps"), an invention by Emden Gansner, Yifan Hu, and
Stephen Kobourov. Try the cool interactive demos showing maps of
music, TV, books, and more.
For people (like us) that care about such matters, we worked pretty
hard to tweak the font rendering code, to eliminate glitches causing
off-center labels or the ransom-note effect.
John Ellson finished porting Graphviz to Solaris OpenCSW.
We changed our license to the EPL (Eclipse Public License). (A
wikipedia article attempts to explain the differences, which we
believe to be fairly limited but the change may help some commercial
licensees.)
to address issues with NetBSD-6(and earlier)'s fontconfig not being
new enough for pango.
While doing that, also bump freetype2 dependency to current pkgsrc
version.
Suggested by tron in PR 47882
a) refer 'perl' in their Makefile, or
b) have a directory name of p5-*, or
c) have any dependency on any p5-* package
Like last time, where this caused no complaints.
cairo revbump earlier this month and was probably meant to be part of a
yet-uncommitted update. It doesn't appear to be correct with the current
version.
PLIST of doxygen varies depending on graphviz configuration.
Say, graphviz configured with PKG_OPTIONS.pangocairo yes or no.
Graphviz/buildlink3.mk will set PKG_BUILD_OPTIONS.graphviz
for use with doxygen PLIST variation.
Thanks Ian McWilliam for reporting and testing the problem.
alternative from mk/jpeg.buildlink3.mk
This allows selection of an alternative jpeg library (namely the x86 MMX,
SSE, SSE2 accelerated libjpeg-turbo) via JPEG_DEFAULT=libjpeg-turbo, and
follows the current standard model for alternatives (fam, motif, fuse etc).
The mechanical edits were applied via the following script:
#!/bin/sh
for d in */*; do
[ -d "$d" ] || continue
for i in "$d/"Makefile* "$d/"*.mk; do
case "$i" in *.orig|*"*"*) continue;; esac
out="$d/x"
sed -e 's;graphics/jpeg/buildlink3\.mk;mk/jpeg.buildlink3.mk;g' \
-e 's;BUILDLINK_PREFIX\.jpeg;JPEGBASE;g' \
< "$i" > "$out"
if cmp -s "$i" "$out"; then
rm -f "$out"
else
echo "Edited $i"
mv -f "$i" "$i.orig" && mv "$out" "$i"
fi

pkgsrc changes: fix a bit of pkglint. Todo: add an option to enable smyrna.
