python-igraph 0.11.8, the seventh bugfix release of the 0.11 series, has arrived. The primary reason for this release is to update the C core of igraph to 0.10.14, which brings a few bugfixes and also a few new functions to the Python interface. This release also adds support for Python 3.13. Please refer to the changelog for more details.

The preferred way of installing the Python interface is via pip; typing pip install igraph should install a pre-compiled Python wheel on most supported platforms (Windows, Linux and macOS). The pre-compiled wheels and the source code are also available from the Python Package Index page.

Read on for more details about the changes in version 0.11.8.
