General

    +
  1. New: OpenCASCADE::read_IGES() and OpenCASCADE::read_STEP() have + been unified in behaviour, and now they allow to extract *all* elements of + the IGES and STEP files instead of only the faces. This allows the + use of iges files describing edges only to be used as input for some of + the OpenCASCADE Manifold wrappers. +
    + (Luca Heltai, 2015/12/13) +
    2. +
  2. New: There is now a function Utilities::to_string that works like int_to_string, but is more safe for long integers, negative integers, and also handles floating point numbers.
