Dear CrystFEL users and interested crystallographers, CrystFEL version 0.9.0 has been released! This release adds a new indexing method ("PinkIndexer") and improvements to reflection prediction which will enable data processing for wide bandwidth and electron diffraction experiments. A new core program has been added, "cell_tool", which can perform several useful tasks on unit cells such as transformation, finding indexing ambiguities and calculating power ring positions. There have been many other improvements across the whole suite. Notably, CBFlib is no longer required by CrystFEL, manual resolution limits are no longer needed by ambigator, and "--no-cell-combinations" is no longer needed by indexamajig. See the release notes for more discussion of these improvements, and the ChangeLog for full details of the other improvements. Thanks for all of your past and future feedback and contributions, and your continued use of CrystFEL.
