Dear Firedrakers, We have now merged the PyOP2 and COFFEE complex branches too. This means that the only special branches you need for complex are Firedrake and tsfc. The installation instructions have been updated accordingly: https://github.com/firedrakeproject/firedrake/projects/4 Existing firedrake complex installations should be updated with: cd src/COFFEE git checkout master cd ../PyOP2 git checkout master firedrake-update You should run firedrake-status to check that only the firedrake and tsfc components are still on the complex branch. Regards, David
