About igraph releases and other things

C/igraph 0.9.0

Release 0.9.0 of igraph’s C core has arrived, almost exactly one year after the latest minor release, 0.8.0. This release brings several new features and improvements, and also a complete switch from the old autotools-based build system to a new one based on CMake. This results in faster build times and the opportunity to use alternative build tools instead of make; in particular, igraph now support ninja and can also make use of a locally installed ccache compiler cache for even faster builds.

We gratefully acknowledge support from CZI for the development of igraph. In addition, we would like to thank everyone who reported issues, contributed features or fixes, or edited the documentation. igraph is an open-source project run by volunteers. As always, your contributions are very welcome!

Most people use igraph through its high-level interfaces for R, Python or Mathematica. A new release of the Python interface, based on 0.9.0, is expected to be released in a few days. The R and Mathematica interfaces already include some of the improvements, and will continue to integrate more.
