Release Notes for Dymos 1.0.0

March 25, 2021

This is version 1.0.0 of Dymos.
This release primarily removes some deprecated experimental features, along with implementing a few bug fixes.

Backwards Incompatible API Changes & Deprecations

  • The RungeKutta Transcription is removed. #550
  • Two-character location specifiers ('++', '--', '+-', '-+') are removed in favor of 'initial' and 'final' #556
  • User must now specify solve_segments='forward' or solve_segments='backward' when using solve_segments capability (True is no longer valid). #557
  • add_input_parameter and add_design_parameter dropped in favor of add_parameter. #558 #561
  • Removed the deprecated command line interface due to it being a somewhat hackish abuse of OpenMDAO's hooks. #563
  • Removed the deprecated 'disc' node subset in favor of the more correct 'state_disc' #565
  • Removed the deprecated 'custom_targets' option for parameters.' #565

Enhancements

  • User will now be warned when multiple timeseries outputs were attempted with the same name. #567

Bug Fixes

  • The ode_class option of phase is now marked non-recordable. #555
  • Fixed doc building due to a change in OpenMDAO. #564

Miscellaneous

  • Modified examples to use the preferred fix_initial=True for time and states instead of "pinched bounds", e.g. initial_bounds=(0, 0). #560
