- update to 2.49.1:
- the CMake build system installs gzipped man pages if `gzip` is available #1883
- CMake projects using Graphviz as a subproject (`add_subdirectory`) can now
link against and use `gvc`.
- various problems in the generation of Javascript bindings
- 2.48.0: test suite is failing #2112
- Ensure correct file-level dependency for generated file in cmake generated
projects #2119
- compile failures with a C++20-compatible toolchain #2122
- compile errors on macOS when using Bison 3.8 #2127
- Make Graphviz buildable as a cmake subproject/subdirectory #1477
- Header not found in Cmake project #2109
- a very basic C++ API for a subset of the functions in lib/cgraph and
lib/gvc, allowing a graph to be rendered from DOT source to a
specified format. The new API is available through two new
libraries: lib/cgraph++ and lib/gvc++. It is experimental, meaning
that it might have breaking changes also in upcoming patch or minor
releases (towards #2001)
- CMake builds now support an `with_expat` option that allows the support for
using HTML-like labels through the optional expat library to be explicitly
enabled (default) or disabled
- CMake builds now support an with_zlib option that allows the support for
raster image compression through the optional zlib library to be explicitly
enabled (default) or disabled
- the CMake build system now enables `-Wextra` when building C++
- some Cgraph functions that take `char*` arguments that they do not modify have
been updated to take `const char*` arguments #634
- incorrectly using the `layout` attribute on anything other than a graph now
results in a warning about this being invalid #2078
- `edgepaint` accepts more standard `--` prefixed command line arguments and
