A couple of days ago we changed how we use GitHub for igraph development. Our goal is to make igraph development more accessible, and our build process simpler. Instead of using a common repository for everything, we now use separate repos for the igraph C library, the R package and the Python extension. The igraph.org website was already in a separate repository, and we will also break up the R package, by putting loosely coupled parts in their own packages and repositories.

Main igraph repositories now:

• igraph C library: https://github.com/igraph/igraph
• igraph R package: https://github.com/igraph/rigraph
• python-igraph: https://github.com/igraph/python-igraph
• igraphdata R package: https://github.com/igraph/igraphdata
• igraph.org homepage: https://github.com/igraph/igraph.org
