- Patch for lefty on OpenBSD removed (lefty is not installed anymore). - Patch for configure.ac modified (list Github Issue #370 and remove hunk for OCaml that does no longer work). - Patch for version.m4 removed (no longer required). - Explicit dependency for urw-fonts added. - Warning suppression for GCC 2 removed. - swig is now a tool dependency (as documented by upstream). - Guile option removed (already broken with older package versions). - OCaml option removed (already broken with older package versions). - Lua, Perl and Tcl language extension options are now disabled by default (to reduce expensive dependencies). 5.0.0 - 2022-07-07 ================== Changed ------- - `use_sanitizers` option has been removed from the CMake build system. Fixed ----- - *Breaking*: The 4.0.0 change replacing the `Agiodisc_t` struct member `putstr` by `printf` has been reverted - graphviz-4.0.0: build error: cmd/tools/gvcolor.c:159: undefined reference to `fmax` #2246 - Failed assertion in `chkSgraph` for twopi layout and ortho splines. #14 - Failed assertion in `chkSgraph` for dot layout and ortho splines. #1408 - Failed assertion in `chkSgraph` for circo layout and ortho splines. #1990 - Segmentation Fault with splines="ortho". #1658 - Transparent Label appear in SVG output #146 - Binary tcl modules should compile with -module #1285 - b15.gv crashes dot #827 - heap overflow in function startElementHandler in gxl2gv.c #2093 - Crash on assertion #121 - `xdotversion` attribute is no longer misparsed. This was a regression in Graphviz 2.47.2. #358 4.0.0 - 2022-05-29 ================== Changed ------- - *Breaking*: The `mark` field of the `Agnodeinfo_t` struct is now a `size_t` instead of a `char`. - *Breaking*: The unused `shape_t` struct has been removed from the public header `types.h` - *Breaking*: The `Agiodisc_t` struct member `putstr` that was previously an `fputs` analog is replaced by `printf` that is required to behave similar to `fprintf`. - the `mingle`, `diffimg`, `gvmap`, and `edgepaint` binaries are now included in the CMake build system - the `gvmap.sh` and `vimdot` scripts are now installed by the CMake build system on operating systems other than Windows - a brief note about the (previously undocumented) behavior of Graphviz when sent `SIGUSR1` is now mentioned in the man page - build system support for `dotty`, `lefty`, and `lneato` has been removed - the CMake build system now includes the DevIL, GDK, GhostScript, GTK, LASi, Poppler, Quartz, Rsvg, Visio, WebP, and Xlib plugins - `awk` is no longer a build-time dependency #2118 Fixed ----- - `agcanon`, `agcanonStr`, and `agwrite` now return error values on memory allocation failures instead of crashing or corrupting data - `gvpr` programs can now pass dynamically allocated arguments to user-defined functions without corrupting their content. Some cases of this were a regression in Graphviz 2.46.0. Other cases have existed since the first release of `gvpr`. #2185 - spurious "no hard-coded metrics" warnings on labels with empty lines #2179 - fixed corruption of user shape characteristics during EPSF initialization - output formats canon, dot, and xdot are not completely faithful to input #2184 - gvpr index function produces wrong results #2211.

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 `bool`s instead of Graphviz-specific `boolean`s. Similarly the `ignoreSwap` and `isOrtho` members of this struct must now be C99 `bool`s instead of a Graphviz-specific `boolean`s. - *Breaking*: The `defined`, `constrained`, `clip`, and `dyna` fields of the `port` struct are now C99 `bool`s instead of Graphviz-specific `boolean`s. - *Breaking*: The `set` and `html` fields of the `textlabel_t` struct are now C99 `bool`s instead of Graphviz-specific `boolean`s. - *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 `bool`s instead of Graphviz-specific `boolean`s. - *Breaking*: The `filled`, `landscape`, and `centered` fields of the `layout_t` struct are now C99 `bool`s instead of Graphviz-specific `boolean`s. - *Breaking*: The `has_images`, `has_flat_edges`, `has_sourcerank`, `has_sinkrank`, `expanded`, and `exact_ranksep` fields of the `Agraphinfo_t` struct are now C99 `bool`s instead of Graphviz-specific `boolean`s. - *Breaking*: The `clustnode` and `has_port` fields of the `Agnodeinfo_t` struct are now C99 `bool`s instead of Graphviz-specific `boolean`s. - *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 `bool`s instead of Graphviz-specific `boolean`s. - *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 `bool`s instead of Graphviz-specific `boolean`s. - *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 `bool`s instead of Graphviz-specific `boolean`s. - *Breaking*: The `fixed` member of the `pack_info` struct is now an array of C99 `bool`s instead of an array of Graphviz-specific `boolean`s. 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](https://clang.llvm.org/docs/LeakSanitizer.html) 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.
