 Note that due to a mistake during the release process, version `3.12.0` was not
 published to opam and should not be used.
+
+This version contains many fixes but we would like to highlight the following
+features:
+
+- `dune ocaml doc` is a new command that will build the docs of your package,
+  and open them in a web browser directly.
+- a new set of odoc rules will build documentation for the whole switch. It can
+  be invoked by `dune build @doc-new`. Note that this is still experimental.
+- Dune can now be built and installed on Haiku.
