Hi,

It is my pleasure to announce a new release of [OCamlGraph](https://github.com/backtracking/ocamlgraph), a graph library for OCaml. It is already available in opam and it is documented [here](http://backtracking.github.io/ocamlgraph/).

Among other things, this release fixes an embarrassing bug in functions `Dfs.fold` and `Dfs.fold_component`, which were actually not implementing a depth-first traversal (yet a graph traversal). See the excellent post [Stack-based DFS is tricky to get right](https://11011110.github.io/blog/2013/12/17/stack-based-graph-traversal.html) for an explanation.

Note: We have deprecated the support of package `ocamlgraph_gtk`, a tool to display graphs using GTK. If you are using this package, please [make an issue](https://github.com/backtracking/ocamlgraph/issues) and we’ll discuss the options.

Jean-Christophe
