diffsims is an open-source Python library for diffraction simulations. This minor release provides some new features and internal improvements. The code remains in active development and updating to this version may break existing code, despite our efforts to make it clear when diffsims changes in a "breaking" fashion. See the list of closed PR's and issues avaliable here for details. Overview A range of internal changes have been made that improve speed, accuracy and readability. These most notably effect the generation of rotation list (which now makes use of the package orix) and the organisation of "geometric" (as opposed to "atomic") kinematical spot pattern simulations. Breaking changes Almost all functionality that has been touched in this release may have changed incompatibly with the previous minor version. New Features Kinematical scaling functions can now be specified by the user (#118) Simulation code that previously lived in pyxem has been migrated here (#101) A new class, ReciprocalLatticePoint for storing a crystal structure has been implemented (#111) Improvements Rotation list grids have been substantially improved by making use of orix (#104 and #115) Bugfixes Multiple bugfixes for ProfileSimulation and associated methods (#102 and #119) Misc and Dev The credits now accurately reflect the contribution of @robtovey (#113)
