McSAS 1.3.1

Changes in v1.3.1:

• Bugfix for high aspect ratio cylinders
• Fix for alignment problems of bars in the histograms
• Updated the isotropically scattering cylinder model to use the
  (faster) SASfit equation
• Added switch for limiting background values to positive values only.
• Switched to trapezoidal smearing by default
• Plotting fixed for incomplete input data
• Fixed syntax error in experimental NXcanSASFile
• Bugfix for 'could not plot background' on Windows
• Change extension of archive to hdf5 to make it understood by
  receiving programs (Dawn, Origin)

McSAS 1.3

Changes in v1.3:

• Adjustable rebinning method for input data prior to fit process
• Optional lower and/or upper clipping of input data
• User extensible models: All models are dynamically loaded from
  the models directory on startup. Just drop your own custom .PY
  model file in there. Please, see the existing models for examples.
• Complete fit configuration is written to HDF5 file .mh5
• Added intensity (vol²) and surface weighted histograms
• No default histogram ranges anymore, the user is asked for a range
  if none is defined
• Remembered histogram ranges for each model between program sessions
• Alternative Goodness-of-Fit indicator output added,
  see [Henn 2016]: http://dx.doi.org/10.1107/S2053273316013206
• Current repetition included in progress log message
• Numerical results of series analysis written to a single file
  for all active parameters
• Internal UI improvements, removed unused/obsolete/redundant code
• Many bug fixes and small improvements
• Python3 compatibility, but standalone packages still use Python2
