v0.5.0

[0.5.0] - 2026-06-14: scale-invariant parallelism, angle and rotation assertions

Minor release. Fixes the scale-dependence of the parallel check and adds an angle-between assertion and a proper-rotation matrix assertion.

Fixed

• AreParallel / IsParallelTo are now scale-invariant. The check compared the raw cross-product magnitude |u x v| against an absolute tolerance, so whether two vectors read as parallel depended on their length, not just their direction: the same angular deviation passed at unit scale and failed at large scale. It now compares the sine of the angle, |u x v| / (|u| |v|), against the tolerance (an angular measure), the same normalization the package already applied in IsCollinear. A zero or shorter-than-tolerance vector is still treated as parallel to any vector. Tolerances chosen for unit vectors are unchanged in meaning; tolerances applied to non-unit vectors now express an angle rather than a magnitude.

Added

• Assert.That(vector).HasAngleBetweenApproximately(other, expectedRadians, tolerance) asserts the unsigned angle between two vectors (on [0, pi]) is within tolerance of an expected value. The angle is computed as atan2(|u x v|, u . v), which stays accurate across the whole range where acos of the normalized dot product loses precision near 0 and pi. LinearAlgebra.AngleBetween(u, v) exposes the same computation on the framework-agnostic core.
• Assert.That(matrix).IsRotation(tolerance) asserts a Matrix4x4 is a proper rotation: orthogonal (M * M^T = I) with determinant +1. Reflections (determinant -1) and matrices carrying translation or scale are rejected. Exposed on the core as LinearAlgebra.IsRotation.

Changed

• Bumped PackageValidationBaselineVersion from 0.4.2 to 0.4.3 on both packages so ApiCompat strict-mode validates 0.5.0 against the most recently published baseline.

v0.4.3

[0.4.3] - 2026-06-12: double-precision magnitude for IsNormalized and HasMagnitudeApproximately

Patch release. Computes vector and quaternion magnitudes in double precision so a tight tolerance reflects the value's actual deviation from unit length rather than single-precision arithmetic noise. No public API change.

Fixed

• IsNormalized (Vector3 and Quaternion) and HasMagnitudeApproximately (Vector3) now compute the magnitude in double precision. They previously called System.Numerics.Vector3.Length() / Quaternion.Length(), which compute the dot product and square root in float. The residual single-precision error could defeat a tight tolerance: a quaternion normalized to float precision could fail IsNormalized at a small tolerance, and at large coordinates the float square overflows to infinity, which makes HasMagnitudeApproximately unsatisfiable. The components now widen to double before the sum of squares and the square root, the same widening already used for PositionDistance and the 0.4.1 quaternion-angle fix. The comparison semantics and the meaning of tolerance are unchanged.

Changed

• Bumped PackageValidationBaselineVersion from 0.4.1 to 0.4.2 on both packages so ApiCompat strict-mode validates 0.4.3 against the most recently published baseline. No public API change; only the assembly-version suppression's target moves.

v0.4.2

[0.4.2] - 2026-06-05: pose-tolerance migration and projection docs

Documentation and release-tooling patch. No code, public API, or behavior change; the 0.4.1 ApiCompat baseline surface is unchanged.

Changed

• README adds a "Migrating from a per-component quaternion tolerance" note under the pose section: rotationToleranceDegrees is a geodesic angle in degrees, not a per-component quaternion delta, so a component epsilon must not be reused as the rotation tolerance. The note gives the rough angle-to-component mapping (a component tolerance ε corresponds to about 115·ε degrees) so a fresh degrees value can be chosen.
• README adds a "Projecting a non-System.Numerics pose" example: IsPoseApproximatelyEqualTo operates on System.Numerics, so a pose arriving as another shape (for example a protobuf message with separate position and orientation fields) is projected to Vector3 / Quaternion first, with a short conversion snippet.
• The packed package README cross-references the migration note from the PoseAssertions entry.
• Bumped PackageValidationBaselineVersion from 0.4.0 to 0.4.1 on both packages so ApiCompat strict-mode validates 0.4.2 against the most recently published baseline. Documentation-only; no CompatibilitySuppressions.xml change.
• The release workflow now publishes the matching CHANGELOG.md section as the GitHub release body (body_path), so release notes carry the full hand-written detail instead of GitHub's auto-generated commit summary.
