Dune 2.6.0 has finally been released. You can download the tarballs, checkout the v2.6.0 tag via Git, or hopefully soon get prebuilt packages from Debian unstable.

Included in the release are the core modules (dune-common, dune-geometry, dune-grid, dune-grid-howto, dune-istl, dune-localfunctions) and at this point in time the dune-alugrid module. Others soon to follow. Details on the changes can be found in the release notes.
