graphviz-12.0.0

[Bruce Dubbs]

New major version.

[Xi Ruoyao]

Added

• Support for building the Graphviz TCL bindings has been integrated into the CMake build system. This is controllable by the -Denable_tcl={AUTO|ON|OFF} option.
• Support for building the SWIG-generated TCL language bindings has been integrated into the CMake build system. This is controllable by the -Denable_swig={AUTO|ON|OFF} option.
• Support for building the SWIG-generated C# language bindings has been integrated into the CMake build system. This is controllable by the -Denable_sharp={AUTO|ON|OFF} option.

Changed

• The Catch2-based test suite in the CMake build system has been ported from Catch2 v2 to Catch2 v3. Support for Catch2 v2 has been removed. #2465
• The Windows release artifacts are now built on Windows 2022 and Visual Studio 2022 17 and toolset v143.
• The macOS release artifacts are now built on macOS 13 (Ventura).
• The CMake build system no longer links dot_builtins against libsocket.
• The CMake build system now only compiles dot_builtins if building shared libraries (-DBUILD_SHARED_LIBS=ON).
• Breaking: the polygon_t.style member is now a struct.
• Breaking: the LEN and MAXDOUBLE constants have been removed.
• Accuracy in processing compass points has been improved.
• Breaking: the CMYK_BYTE member of the color_type_t enum and the corresponding gvolor_t.u.cmyk field have been removed. The color format this mapped to was neither documented nor implemented correctly.
• The Windows releases available for download on graphviz.org now only include CMake-produced packages, not MS Build-produced packages. The MS Build packages are available in the ​Gitlab package registry if needed.
• The CMake build system more pervasively sets rpaths of compiled binaries, libraries, and plugins, which should result in them more reliably finding their supporting components. without $LD_LIBRARY_PATH/$DYLD_LIBRARY_PATH tricks.
• Breaking: the Agraph_t.n_id field is now an opaque pointer.
• Breaking: the libpack functions putGraphs, putRects, and shiftGraphs now operate on floating-point points (pointf) instead of integer points (point).
• Breaking: the BF2B macro has been removed.
• Breaking: the undocumented -Tmp output format has been removed.
• Breaking: the arith.h header defines neither _GNU_SOURCE nor sincos any more. None of the build systems attempt to discover sincos any more.
• The FIG output format (-Tfig) supports up to 512 custom colors. The previous limit was 256, after which it would crash (see note in the “Fixed” section).
• Breaking: The TCL binding’s tcldot_layout function no longer tries to fallback to the dot layout engine if the requested engine is unavailable but instead fails with an error message.
• The TCL binding’s graph render command no longer ignores layout errors.
• The TCL binding’s graph write command now does layout unconditionally, regardless of what output renderer is selected.
• The CMake build system builds cgraph++ and gvc++ as either shared or static libraries, respecting the BUILD_SHARED_LIBS setting.
• Discovery of the fcntl.h header has been removed from all build systems. This header is now unconditionally assumed to exist.
• Breaking: obj_state_t.gradient_frac is now a double.
• Breaking: path.nbox is now a size_t.
• The change described as “Some routesplines miscalculations that led to lost edges and fatal errors have been avoided” in 11.0.0 has been reverted. The fix for this caused other problems.
• Breaking: the d and disc parameters have been removed from Dtcompar_f.
• CentOS packages are no longer provided.
• In the CMake build system, the minimum required CMake version has been increased to 3.14.1.
• Breaking: the disc parameter has been removed from Dtfree_f.
• Gvedit no longer depends on the getopt library.

Fixed

• The CMake build system now uses absolute paths to PangoCairo libraries during linking, resolving build problems on macOS.
• The CMake build system’s path for third-party headers for the DevIL plugin has been corrected.
• Edges not rendering properly when using ports and the crow arrowhead/tail with Windows Release builds. #2490
• A duplicate prototype of aghtmlstr has been removed.
• agrelabel_node (or equivalently, agrename when operating on a node) no longer corrupts the node-by-id set, causing a crash. This bug was preventing gxl2gv from processing inputs that used node name attributes. #2300
• Accuracy improvements have fixed an assertion failure on macOS. #2538
• The FIG output format (-Tfig) no longer crashes when handling more than 256 colors.
• The scale operation implemented by the TCL binding’s tclpathplan scales relative to the center of the points being scaled instead of reading uninitialized memory.
• The xlib plugin sets “close-on-exec” on the file descriptors it creates, preventing them leaking into either web browsers it starts or other processes created by the hosting application.
• A sign confusion issue in neatogen’s weighting calculations was fixed. This was a regression in Graphviz 11.0.0.
• The CMake build system no longer attaches dllimport/dllexport annotations when compiling static libraries on Windows and MinGW.
• An issue with linking gvpack when building static libraries in the CMake build system was fixed.
• An sfdp use-after-free issue was fixed. #2556
• Using concentrate=true once again works. This was a regression in Graphviz 11.0.0. #2559
• overlap="scale" no longer causes nodes to be placed on top of one another. This was a regression in Graphviz 7.0.5. #2564
• libpack code 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, #2555

Note that the awk command can be removed.

I suspect this will break 1 or 2 packages but we'll deal with it as updates roll in
