Dear Firedrakers, As of today, Firedrake integrates with Zenodo. What this means for you is that there is a streamlined mechanism for generating a set of DOIs which record the precise version of Firedrake and its dependencies which you used in a publication. We think this is a big step towards best practice reproducible computational science. The instructions on how to use this are documented at: http://firedrakeproject.org/zenodo.html One side effect of this is that Firedrake's forks of FIAT, UFL, PETSc and PETSc4py are now on GitHub rather than Bitbucket. Your Firedrake install should automatically pick up the new repositories next time you run firedrake-update. If you are using your own branches of any component, these will also automatically repoint at the GitHub repo rather than Bitbucket, so future changes and pull requests will happen on GitHub. Regards, David
