Today, we released BornAgain-24.1. This minor release improves here and there over recent 24.0: Dependencies: - Require libheinz-4.1; this fixes a NaN from acos(1+eps). New functionality: - Slicing supported for all polyhedral form factors. - All polyhedral form factors allowed as Mesocrystal outer shape. - Real-space 3D viewer got "Save" button and optional beam visualization. Performance: - F(q) is reused for identical particles in Compound and Mesocrystal. - In the reciprocal-space mesocrystal mode, basis form factors are reused across detector pixels. Bug fixes: - Correct Bipyramid4 slicing. - Correct is-in-Mesocrystal computation for Pyramid3 and Pyramid6 outer shapes. - Correct slicing for rotated Compound, Mixture and CoreAndShell. - Correct material average for deposited and suspended particles. - IParticle::rotate now carried out around the particle reference point, so that rotate and translate commute. - Mesocrystal position variance now contributes to incoherent covariance. - Fit examples no longer crash in the final showSample3D call. More details in the CHANGELOG. Greetings from the BornAgain maintainer team: Ammar Nejati, Mikhail Svechnikov, Joachim Wuttke
