Version 1.3.0

  • Changes:
    • Rework of plugin system. (#409 - #417)
      • Plugin group identifier is now fastoad.plugins (usage of fastoad_model is deprecated)

      • A plugin can now provide, besides models, notebooks and sample configuration files.

      • CLI and API have been updated to allow choosing the source when generating a configuration file, and to provide the needed information about installed plugin (fastoad plugin_info)

      • Models are loaded only when needed (speeds up some basic operations like fastoad -h)

    • CS25-related models are now in separate package [FAST-OAD-CS25]( This package is still installed along with FAST-OAD to preserve backward-compatibility. Also, package [FAST-OAD-core]( is now available, which does NOT install FAST-OAD-CS25 (thus contains only the mission model). (#414)

    • IndepVarComp variables in FAST-OAD models are now correctly handled and included in input data file. (#408)

    • Changes in mission module. Most noticeable change is that the number of engines is no more an input of the mission module, but should be handled by the propulsion model. No impact when using the base CS-25 process, since the variable name has not changed.(#411)

  • Bug fixes:
    • FAST-OAD is now able to manage dynamically shaped problem inputs. (#416 - #418)

Version 1.2.1

  • Changes: - Updated dependency requirements. All used libraries are now compatible with Jupyter lab 3 without need for building extensions. (#392) - Now Atmosphere class is part of the [stdatm]( package (#398) - For list_variables command, the output format can now be chosen, with the addition of the format of variables_description.txt (for custom modules now generate a variable descriptions. (#399)

  • Bug fixes: - Minor fixes in Atmosphere class. (#386)

  • Bug fixes:
    • Compatibility with OpenMDAO 3.10 (which becomes the minimal required version). (#375)

    • Variable descriptions can now be read from comment of XML data files, which fixes the missing descriptions in variable viewer. (#359)

    • Performance model: the computed taxi-in distance was irrelevant. (#368)

    • Errors in custom modules are no more hidden. (#348)

Version 1.0.3

  • Changes:
    • Configuration files can now contain unknown sections (at root level) to allow these files to be used by other tools. (#333)

  • Bug fixes:
    • Importing, in a, some classes that were registered as FAST-OAD modules could make that the register process fails. (#331)

    • When generating an input file using a data source, the whole data source was copied instead of just keeping the needed variables. (#332)

    • Instead of overwriting an existing input files, variables of previous file were kept. (#330)

    • A variable that was connected to an output could be incorrectly labelled as input when listing problem variables. (#341)

    • Fixed broken links in Sphinx documentation, including docstrings. (#315)

Version 1.0.2

  • FAST-OAD now requires a lower version of ruamel.yaml. It should prevent Anaconda to try and fail to update its “clone” of ruamel.yaml. (#308)

      • Connection of OpenMDAO variables can now be done in configuration file. (#263)

  • Added compatibility with OpenMDAO 3.4, which is now the minimum required version of OpenMDAO. (#231)

  • Simplified call to VariableViewer. (#221)

Version 0.4.2-beta

  • Prevents installation of OpenMDAO 3.2 and above for incompatibility reasons.

  • In Breguet module, output values for climb and descent distances were 1000 times too large (computation was correct, though).

Version 0.2.2-beta

  • Changed dependency requirement to have OpenMDAO version at most 3.1.0 (FAST-OAD is not yet compatible with 3.1.1)

Version 0.2.1-beta
