v3.3.0

VortexStepMethod v3.3.0

Diff since v3.2.0

Added

• ForwardDiff compatibility, used by default in linearize (#232)
• backend keyword argument for linearize
• example linearize_check.jl comparing FiniteDiff and ForwardDiff tangents

Changed

• core structs are parameterized on the scalar type T so dual numbers can
  propagate through them; public constructors are unchanged

Merged pull requests:

• Add forwarddiff compatibility and use it for linearisation (#232) (@1-Bart-1)
• Add constructor without type (#233) (@1-Bart-1)

v3.2.0

VortexStepMethod v3.2.0

Diff since v3.1.3

Added

• support for both CairoMakie and GLMakie in the example menu() via new
  CairoMakie.activate() / GLMakie.activate() entries (#222)
• plots are saved as PDF when CairoMakie is active
• bin/install now creates the output folder used by examples to store
  generated plots

Changed

• examples write plots into the shared output folder instead of the working
  directory
• example plot file names are sanitized: spaces replaced with _ and %
  replaced with pct

Fixed

• NONLIN solver no longer returns stale gamma on repeated solve! calls
  (#228)

v3.1.3

VortexStepMethod v3.1.3

Diff since v3.1.2

### Fixed
- bug in `linearize` where `body_aero.va` was used instead of `body_aero._va`,
  causing incorrect initial velocity storage (#227)
- `set_va!` no longer overwrites `_va` with a computed reference velocity when
  omega is nonzero; this simplifies the function and fixes linearization with
  turn rates
- linearize now correctly preserves and restores `omega` across perturbations

Breaking

• billowing_angle replaced by billowing_percentage on Wing and
  WingSettings (percentage of arc length, not radians)

• the function menu_cp() can now be used to run the examples with the ControlPlots backend

• the files Manifest-v1.11.toml.default and Manifest-v12.toml.default for enhanced reproducibility
• the scripts bin/jetls and bin/jetls_examples for running a static check of the source code
• the script test_bench.jl for benchmarking the refinement method and measuring allocations

Changed

• Plot legends moved to shared horizontal legend at the bottom of grid layouts
• the script bin/run_julia now can be called with a script name as a parameter
• fixed all JETLS warnings in the source code for improved performance and stability

Fixed errors

• Domain error in elliptical gamma distribution when control points lie
  outside the nominal span envelope

Breaking Changes

Unified Wing type

• Wing and RamAirWing merged into a single Wing struct
• RamAirWing constructor replaced by ObjWing (returns a Wing with
  OBJ-specific fields populated)
• Renamed ram_geometry.jl → obj_geometry.jl

Unrefined sections replace panel grouping

• n_groups replaced by n_unrefined_sections in Wing, WingSettings, and
  SolverSettings
• PanelGroupingMethod enum removed
• Each refined panel maps back to its unrefined section via
  refined_panel_mapping
• n_groups and grouping_method in YAML settings files emit a deprecation
  warning and are ignored

Renamed VSMSolution fields (_array → _dist)

• panel_width_array → width_dist
• alpha_array → alpha_dist
• cl_array → cl_dist, cd_array → cd_dist, cm_array → cm_dist
• panel_lift → lift_dist, panel_drag → drag_dist
• panel_moment → panel_moment_dist
• group_moment_dist → moment_unrefined_dist
• Type parameter Solver{P,G} / VSMSolution{P,G} changed to Solver{P,U} /
  VSMSolution{P,U} (U = unrefined sections)

Mesh refinement separated from reinit

• reinit! no longer re-refines the mesh; it only updates panel properties from
  existing refined_sections
• New refine! function handles mesh refinement explicitly

Changed

• Consistent naming convention: _dist = per-panel, _unrefined_dist =
  per-unrefined-section
• correct_aoa solver setting added (default false)
• alpha_geometric is now the angle between apparent wind and chord
• Panel width calculation uses sum instead of average
• src/plotting.jl removed; all plotting moved to Makie and ControlPlots
  extensions
• TestEnv no longer required as a global dependency

Added

• n_unrefined_sections field in Wing for tracking pre-refinement sections
• refined_panel_mapping for automatic panel-to-section association
• Unrefined distribution fields in VSMSolution: cl_unrefined_dist,
  cd_unrefined_dist, cm_unrefined_dist, alpha_unrefined_dist,
  moment_unrefined_dist, width_unrefined_dist
• alpha_geometric_dist field in VSMSolution
• unrefined_deform! for applying twist and TE deflection to unrefined
  sections; non_deformed_sections preserved for reset/re-deformation
• refine! function for explicit mesh refinement
• plot_combined_analysis in the Makie extension
• Literature comparison plotting in the Makie extension
• obj_file and dat_file fields in WingSettings
• sort_sections kwarg for section ordering control
• Separate test/Project.toml and examples/Project.toml
• New tests: test_unrefined_dist.jl, test_refinement_validation.jl,
  test_yaml_wing_deformation.jl

Removed

• RamAirWing type (use ObjWing or Wing directly)
• PanelGroupingMethod enum
• n_groups from WingSettings, SolverSettings, and YAML files
• src/plotting.jl (920 lines moved to extensions)
