v14.1.5

Compare Source

Fixed

• The JSON renderer of the core plugin now understands a cluster to be indicated
  by the common rules, including the “cluster” prefix being case insensitive and
  the cluster=true attribute as an alternative. #​2187
• The description of what defines a cluster subgraph in the gc man page has
  been updated. #​2187
• When rendering multiple files at once (e.g.
  dot -Tsvg -O file1.dot file2.dot), page numbering state from previous jobs
  no longer leaks into the current job. This was a regression in
  Graphviz 2.40.0. #​2827
• Logic to determine whether a rendered page is non-first has been corrected.
• gvpr modulo expressions with an out-of-range modulo operand are now detected
  and result in an error message.
• When gvpr dumps switch statements as text, they are now printed as switch
  statements instead of an if-else ladder. This avoids incorrect interpretation
  of break statements in error messages. #​2822
• An out-of-bounds read access during gvpr type checking has been fixed.
• A null pointer dereference when freeing xdot objects has been fixed.

v14.1.4

Compare Source

Changed

• Enable ascii plugin to be built using autotools. #​2828

Fixed

• Processing concentrate=true graphs no longer crashes Graphviz. Processing of
  concentrate=true graphs still often errors out. #​2825

v14.1.3

Compare Source

Changed

• Using long node names in combination with the fdp layout algorithm no longer
  results in truncated generated names.
• Vertical centering of text within HTML-like table cells has been improved.
• The existing ability to provide a numeric parameter to -v
  to specify verbosity level are newly documented in dot --help.

Fixed

• gvmap no longer dereferences a null pointer when reading position-less
  graphs.
• gvmap no longer crashes when adding coordinate data.
• mm2gv no longer accepts input matrices with non-real element type.
  Previously these would be accepted but processed incorrectly leading to
  out-of-bounds memory reads and writes.
• The Tcldot_Init, Tcldot_builtin_Init, and Tcldot_SafeInit symbols in
  tcldot.dll are externally visible on Windows. #​2809
• The Tclpathplan_Init and Tclpathplan_SafeInit symbols in tclpathplan.dll
  are externally visible on Windows. #​2809
• The Autotools build system more consistently uses $PYTHON3 instead of
  python3 when invoking Python. This ensures developers are more easily able
  to control the Python installation in use from the top level.
• The Autotools build system explicitly links against libglu libraries when
  linking against libglut.
• Corrected time formatting in verbose info/debug messages (enabled by -v).
  Previously, minutes was missing, showing HH:SS instead of HH:MM:SS.
• Further parts of the network simplex algorithm have been rewritten in a
  non-recursive style. This allows processing larger graphs that previously
  caused stack overflows. #​2782
• Canonicalizing an empty string or a string entirely made up of characters
  needing escaping no longer triggers an out-of-bounds memory write. This was a
  regression in Graphviz 13.0.1. #​2743
• An off-by-one error in the network simplex algorithm has been corrected. This
  could have led to suboptimal layout in some edge cases. This was a regression
  in Graphviz 13.0.0.
