- You can now extract fixed Euler ZYZ angles from a IMP::Rotation3D. This code can serve as a template for extracting other Euler angle conventions if they are needed.
- IMP::algebra::rotation_between_two_vectors() changed to IMP::algebra::rotation_taking_first_to_second() to make it clear which direction the rotation goes.
- IMP::Decorator derived objects are now convertible to bool. So code like Âif (d) { ÂÂÂ blah } works.
- IMP::Decorator::cast now returns a null decorator (\c DecoratorName()) rather than throwing an exception. This might make it actually useful. The previous method was entirely unused.
- New IMP::statistics module for statistical methods (e.g. clustering).
