Pymead

New features

- Added a curvature-based downsampling method to Airfoil and implemented as an option in multi-element airfoil analysis and optimization
- Added downsampling preview button and dialog to multi-element airfoil analysis and optimization
- Implemented QSettings paradigm for storing user-level settings outside of pymead
- Dark/light theme choice and last directory used in some "Choose folder" buttons now saved outside of pymead and applied on restart of pymead
- Now check for diff in current displayed airfoil system relative to the load file to determine whether the program can immediately exit without asking to save changes

Bug fixes

- Fixed bug due to change in pyqtgraph API and pinned pyqtgraph version
- Fixed bug where program would exit after the last dialog no matter which button was pressed
- Fixed "top" and "bottom" descriptors being swapped in the GridBounds widget

New features

- Help browser displays the GUI documentation from [readthedocs](https://pymead.readthedocs.io/en/latest/). Also allows for general web browsing
- Curvature-based downsampling algorithm implemented as an option for airfoil coordinates export.

Bug fixes

- Fixed major bug where parameters in the Symmetry and Pos constraint dialogs could not be selected from the Parameter Tree

Feature updates

- pymead now checks GitHub to see if there is a newer release available
- Added internal Screenshot feature under the "Tools" submenu

Bug fixes
- Fixed major bug where control points tied to an AnchorPoint with a constrained radius of curvature would
behave correctly when dragged

Bug fixes

- Accounted for rare error in read of `mplot.log`
- Added files in `setup.py`

Feature updates

- Calculation of CPK by power consumption rather than power input for better accuracy

Bug fixes

- Better handling of user optimization termination

Bug fixes

- Fixed bug where `forces_dict` was not being read properly during optimization warm start
