This release has an MSRV of 1.85.

Added

• The newly added BezPath::into_elements method allows getting all path elements as a Vec without allocating, consuming the original path. This is the counterpart of BezPath::from_vec. (#504 by @cmyr)
• Add a derive Hash to the Axis type. (#527 by @jrmoulton)

Changed

• Speed up methods like Ellipse::radii by reworking the singular value decomposition expression. (#499 by @tomcur)
• The Line::nearest method to calculate the projection of a point onto a line segment has been made more performant. (#505 by @tomcur)
• The QuadBez::arclen calculation has been made more numerically stable (#503 by @jneem).
• SvgParseError now implements core::error:Error. It previously implemented std::error::Error in std-enabled builds. (#517 by @Bombaninha)
• The behavior of open versus closed shapes when using BezPath::extend (extending Bezier paths using an iterator over PathEl) has been clarified. #523 by @DJMcNab)
• More methods are marked inline. (#506 by @LaurenzV, #509 by @tomcur)

The following functions are now callable from const contexts. (#510, #512, #521, #522, #524, #525, #526 by @tomcur)

• Affine::{skew, then_translate, map_unit_square, as_coeffs, determinant, inverse, translation, with_translation}
• Point::midpoint
• Rect::{width, height, origin, size, area, is_zero_area, center, aspect_ratio_width, overlap, contains_rect, union, intersect, inscribed_rect_with_aspect_ratio, inflate, scale_from_origin, abs}
• Size::{max_side, min_side, area, is_zero_area, min, max, clamp, aspect_ratio_width}
• In addition, the is_finite and is_nan methods on the following types are now const: Affine, Circle, ConstPoint, CubicBez, Ellipse, Insets, Line, Point, QuadBez, Rect, RoundedRect, RoundedRectRadii, Size, Triangle, Vec2.
