Hi everyone, Two pull requests were merged today that make some important changes. 1) The boost imports were moved to boost_adaptbx.boost. This avoids claiming the main "boost" namespace. A common piece of code that will need to be changed is import boost.python ext = boost.python.import_ext("your_boost_python_ext") That can be changed to import boost_adaptbx.boost.python as bp ext = bp.import_ext("your_boost_python_ext") Otherwise, a FutureWarning will be raised. More information can be found at https://github.com/cctbx/cctbx_project/issues/458 https://github.com/cctbx/cctbx_project/pull/470 https://github.com/cctbx/cctbx_project/pull/516 2) More dependency repositories were moved from cci.lbl.gov to GitHub. If you use bootstrap.py to build cctbx, you will want to delete annlib, ccp4io_adaptbx, clipper, eigen, gui_resources, tntbx. Using a newly updated bootstrap.py, the copies from GitHub will be used instead. More information can be found at https://github.com/cctbx/cctbx_project/pull/408 Let us know if you have any questions. Thanks! -- Billy K.
