# Changelog

## Unreleased

- Reynolds is stated once: `reynolds(set, wing)` takes the air from
`solver_settings` and the reference speed and chord from `airfoil:`.

### Changed

- BREAKING: `shrink_wrap` traces the rolling ball exactly — pivoting it around
the cloud and offsetting the polygon through the points it touches
(`pivot_contour`) — instead of thresholding and marching-squares-tracing a
distance field, so there is no grid resolution left to set. `ShrinkWrap`'s
`cell_size` is accordingly named `min_clearance`, still accepted under the old
name, and floors `clearance` only for an open single-membrane cloud; a closed
loop keeps its true `clearance`, so `clearance=0` hugs the input and leaves
its sharp trailing edge sharp. The wrap sits at exactly `clearance` from the
cloud instead of a cell over it, so a V3 canopy's aft strip comes out
`2 * clearance` thick where the grid gave `3.5 * cell_size`.
`min_concave_radius` stops costing anything, having padded the grid in both
directions before: one V3 slice at radius 0.4 drops from 173 ms to 10 ms, and
at the default radius from 15 ms to 3 ms.
