  • add end-tethered and mushroom models for polymers
  • support magnetic incident and substrate media
  • support Microsoft Visual C compiler
  • allow stop after a maximum amount of time (useful in batch queues)
  • add entropy calculator

2014-05-30 R0.7.6

  • add levenberg-marquardt to available fitting engines

2014-05-01 R0.7.5

  • display constraints info on graph
  • estimate parameter uncertainty from covariance matrix
  • fix windows binary
  • read magnetic models from reflpak

2014-04-03 R0.7.4

  • demonstrate functional profiles in examples/profile/flayer.py
  • add MPI support
  • add stopping condition for DE
  • support python 2.6, 2.7 and 3.3+
  • fix confidence intervals (old confidence intervals are 2x too small)

  • allow fit interrupt from GUI

2013-05-07 R0.7.1

  • simplify contrast variation fits with free variables shared between models
  • add FASTA sequence reader with support for labile hydrogen substitution
  • redo magnetic profiles so magnetism is a property of nuclear layers
