Changelog:
==========
### Changed
- Internal timing operations now use 'clock()' on all platforms (previously this
was only used on Windows). This should result in more accurate timing in
verbose informational messages.
- Building Graphviz with expat < 2.2.8 is no longer supported on MinGW.
### Fixed
- 'diffimg' now notices failures when calling Ghostscript to convert PS images
to PNG and exits instead of continuing.
- 'dtstat' no longer reads/writes out of bounds memory on platforms where
'sizeof(int) < sizeof(size_t)'. This was a regression in Graphviz 7.0.1.
- Some incorrect variable types in the libcdt man page have been corrected.
- 'gvgen' no longer triggers Undefined Behavior when asked to generate a binary
tree with depth >= 32 (e.g. 'gvgen -t32').
- 'gvgen' no longer triggers Undefined Behavior when asked to generate a
hypercube with depth >= 32 (e.g. 'gvgen -h32').
- A null pointer dereference in edge pair analysis within the circo algorithm
has been fixed.
