BornAgain-22.0, in preparation
  > New or improved functionality:
    * Scan axes have bins of width 0

      for the actual phi, alpha of each pixel.
    * Offspec analyzer is set for detector, not scan(#651)
    * FitObjective::addSimulationAndData has been replaced by function addFitPair,
      which takes experimental data in form of a Datafield object instead of a NumPy array
    * Function ba_plot.plot_histogram is replaced by plot_simulation_result
    * Conversion of plot axes from default to other units now done by functions
      FlatDetector::field2q, field2mm, field2angles

  > Preface:
    This release, the result of two years of intense work, brings huge changes
    at all levels.
      Much of this release is about "refactoring", i.e. internal changes that
    modify neither the user interface nor the outputs, but set data structures
    and internal interfaces right in order to enable future extensions.
      Among the user-facing changes, the most noticeable is the replacement
    of the graphical sample editor by a expandable tables.  Also, there are
    numerous changes to the Python API.  Unfortunately, this means that most
    old scripts will be broken.  We recognize the importance of backward
    compatibility, which we hope to gradually achieve in forthcoming releases.
      The restructured documentation has now three distinct sections for Python
    scripting: a short tutorial, a collection of examples, and a reference.
    Migration to this new structure is still incomplete; some reference sections
    are still in old teaching-by-example style, and will be reworked later.
      In spite of thorough testing, it is quite likely that some bugs slipped in.
    If you suspect a bug or observe any other undesirable behavior, please
    submit a report to our issue tracker.  We will investigate any such report
    with high priority, and publish hotfix releases as appropriate.
      With this release, the version number scheme changed. Recognising that
    there will be never be the right moment to pass from BornAgain 1.x.y to 2.0.0,
    we removed the leading "1" for good, and promoted the old minor to new major.
    In the future, new major releases shall be published several times per year.
