  FAST-OAD configuration file is now in YAML format. (#277)
  
  Module declaration are now done using Python decorators directly on registered classes. (#259)
  
  FAST-OAD now supports custom modules as plugins. (#266)
  
  Added “fastoad.loop.wing_position” module for computing wing position from target static margin in MDA. (#268)
  
  NaN values in input data are now detected at computation start. (#273)
  
  Now api.generate_inputs() returns the path of generated file. (#254)
  
  fastoad list_systems is now fastoad list_modules and shows documentation for OpenMDAO options. (#287)
  
  Connection of OpenMDAO variables can now be done in configuration file. (#263)
  
  More generic code for mass breakdown plots to ease usage for custom weight models. (#250)
  
  DataFile class has been added for convenient interaction with FAST-OAD data files. (#293)

  FAST-OAD was crashing when mpi4py was installed. (#272)
  
  Output of fastoad list_variables can now be redirected in a file. (#284)
  
  Activation of time-step mission computation in tutorial notebook is now functional. (#285)
  
  Variable viewer toolbar now works correctly in JupyterLab. (#288)
  
  N2 diagrams caused a 404 error in notebooks since OpenMDAO 3.7. (#289)
Models:
- Changes:
  
  A notebook has been added that shows how to compute CeRAS-01 aircraft. (#275)
  
  Unification of performance module. (#251)
  
  Breguet computations are now defined using the mission input file.
  
  A computed mission can now be integrated or not to the sizing process.
  
  Better management of speed parameters in Atmosphere class. (#281)
  
  More robust airfoil profile processing. (#256)
  
  Added tuner parameter in computation of compressibility. (#258)

Version 0.5.4-beta¶

Bug fix: An infinite loop could occur if custom modules were declaring the same variable several times with different units or default values.

Version 0.5.3-beta¶

Added compatibility with OpenMDAO 3.4, which is now the minimum required version of OpenMDAO. (#231)
Simplified call to VariableViewer. (#221)
Bug fix: model for compressibility drag now takes into account sweep angle and thickness ratio. (#237)
Bug fix: at installation, minimum version of Scipy is forced to 1.2. (#219)
Bug fix: SpeedChangeSegment class now accepts Mach number as possible target. (#234)
Bug fix: variable “data:weight:aircraft_empty:mass has now “kg” as unit. (#236)

Version 0.5.2-beta¶

Added compatibility with OpenMDAO 3.3. (#210)
Added computation time in log info. (#211)
Fixed bug in XFOIL input file. (#208)
Fixed bug in copy_resource_folder(). (#212)

Version 0.5.1-beta¶

Now avoids apparition of numerous deprecation warnings from OpenMDAO.

Version 0.5.0-beta¶

Added compatibility with OpenMDAO 3.2.
Added the mission performance module (currently computes a fixed standard mission).
Propulsion models are now declared in a specific way so that another module can do a direct call to the needed propulsion model.

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 0.4.0-beta¶

Some changes in mass and performances components:

The Breguet performance model can now be adjusted through input variables in the “settings” section.
The mass-performance loop is now done through the “fastoad.loop.mtow” component.

Version 0.3.1-beta¶

Adapted the FAST-OAD code to handle OpenMDAO version 3.1.1.

Version 0.3.0-beta¶

In Jupyter notebooks, VariableViewer now has a column for input/output type.
Changed base OAD process so that propulsion model can now be directly called by the performance module instead of being a separate OpenMDAO component (which is still possible, though). It prepares the import of FAST legacy mission-based performance model.

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¶

Fixed compatibility with wop 1.9 for XDSM generation

Version 0.2.0b¶

First beta release

Version 0.1.0a¶

First alpha release
