New major version.

Changed

• Breaking: Using Graphviz as a library on Windows now requires the GVDLL symbol to be set to ensure correct linking.
• Breaking: Graphviz headers no longer define the boolean type. A replacement is C99 bool in the C standard library’s stdbool.h.
• Breaking: The insidefn member of the shape_functions struct must now be a pointer to a function returning a C99 bool instead of a Graphviz-specific boolean.
• Breaking: The swapEnds and splineMerge members of the splineInfo struct must now be pointers to functions returning a C99 bools instead of Graphviz-specific booleans. Similarly the ignoreSwap and isOrtho members of this struct must now be C99 bools instead of a Graphviz-specific booleans.
• Breaking: The defined, constrained, clip, and dyna fields of the port struct are now C99 bools instead of Graphviz-specific booleans.
• Breaking: The set and html fields of the textlabel_t struct are now C99 bools instead of Graphviz-specific booleans.
• Breaking: The usershape field of the shape_desc struct is now a C99 bool instead of a Graphviz-specific boolean.
• Breaking: The candidate and valid fields of the rank_t struct are now C99 bools instead of Graphviz-specific booleans.
• Breaking: The filled, landscape, and centered fields of the layout_t struct are now C99 bools instead of Graphviz-specific booleans.
• Breaking: The has_images, has_flat_edges, has_sourcerank, has_sinkrank, expanded, and exact_ranksep fields of the Agraphinfo_t struct are now C99 bools instead of Graphviz-specific booleans.
• Breaking: The clustnode and has_port fields of the Agnodeinfo_t struct are now C99 bools instead of Graphviz-specific booleans.
• Breaking: The conc_opp_flag field of the Agedgeinfo_t struct is now a C99 bool instead of a Graphviz-specific boolean.
• Breaking: The must_inline and nocache fields of the usershape_t struct are now C99 bools instead of Graphviz-specific booleans.
• Breaking: The device_sets_dpi, external_context, fit_mode, needs_refresh, click, has_grown, and has_been_rendered fields of the GVJ_t struct are now C99 bools instead of Graphviz-specific booleans.
• Breaking: The loadimage member of the gvloadimage_engine_t struct must now accept a C99 bool parameter instead of a former Graphviz-specific boolean parameter.
• Breaking: The textlayout member of the gvtextlayout_engine_t struct must now return a C99 bool instead of a Graphviz-specific boolean.
• Breaking: The config and auto_outfile_names members of the GVC_common_s struct are now C99 bools instead of Graphviz-specific booleans.
• Breaking: The fixed member of the pack_info struct is now an array of C99 bools instead of an array of Graphviz-specific booleans. Similarly, pack_graph now takes a bool array instead of a boolean array.
• Breaking: pccomps now takes a C99 bool instead of a boolean output parameter.
• Breaking: gvusershape_file_access now returns a C99 bool instead of a Graphviz-specific boolean.
• Breaking: 1-bit fields of the obj_state_s struct are now unsigned instead of signed.
• Breaking: Graphviz headers no longer define the constant MAXSHORT. A drop-in replacement is SHRT_MAX in the C standard library’s limits.h.
• Breaking: Graphviz headers no lnger define NIL macros. A drop-in replacement is NULL in the C standard library’s stddef.h.
• Breaking: Graphviz headers no longer define the NOT macro. A drop-in replacement is the C/C++ operator !.
• Breaking: Graphviz headers no longer (re-)define the C constants INT_MIN and INT_MAX. Replacements can be found in the C standard library’s limits.h.
• Breaking: Graphviz headers no longer define the constant _DUMMY_ELEM.
• Breaking: The -m memory test option to Graphviz command-line programs has been deprecated. Tools such as Leak Sanitizer are a more effective modern way of diagnosing memory safety issues.
• Breaking: Graphviz headers no longer define the constant MAXFLOAT. A replacement is FLT_MAX in the C standard library’s float.h.
• The Ming plugin that produced Shockwave files has been removed. This format was EOLed by Adobe in April 2019. #2160
• CentOS 7 packages now include libmingle and the mingle program.
• The tclpkg Makefile no longer suppresses -fstack-clash-protection nor other compiler options containing -x
• Lefty is no longer enabled in the portable source tarball.
• on Linux, the CMake build system uses the standard GNUInstallDirs to locate target installation paths

Fixed

• Breaking: GVPR now typedefs ssize_t as SSIZE_T on Windows instead of int #1804
• Breaking: vgpanecmd in the TCL tclpathplan library no longer accepts abbreviated commands (e.g. r for rotate) and commands must be given in full #1961
• fix detection of unavailable output format
• SVG layout doesn't always respect requested size #1855
• mismatched format string in mingle
• Building from scratch with Visual Studio fails #2175
• Plugins are not configured on MinGW #2176
• gvpr on MinGW does not support absolute paths #1780
• PNG format not available in CMake builds with MinGW
• tclpkg Makefile corrupts CFLAGS #2177
• lneato -? sometimes fails with STATUS_STACK_BUFFER_OVERRUN on Windows #1934
• expr misinterprets << and >> #2103
• stdout and stderr are not flushed at exit on MinGW #2178
• Gvedit on macOS now understands the -? help command line argument
• CMAKE_LIBRARY_PATH is not honored #1973
• assert failure with nslimit1=0 #1902
• gvpr usage output has been restored. This was a regression in Graphviz 2.46.0.
• C++ API not usable after install #2196
