## 1.5.1

### Patch Changes

- acbed6b: `DistanceProxy.getSupport` starts at index 0 as in Box2D, so a body whose state has become non-finite no longer makes `World.step()` throw from the time-of-impact solver.
- 6ae0fc1: `TimeOfImpact` returns `e_failed` at once when a sweep is non-finite instead of spending the whole root-finder budget on it; `Sweep.isValid()` is new.
- c48cb32: Fix duplicate contact ids in edge- and chain-vs-polygon manifolds, which let warm-start impulses grow without bound on a jammed body and made `World.step()` throw from the time-of-impact solver (#315). Simulations with such contacts may not replay bit-identically to 1.5.0.

  Fix the inverted `isValid` assertions in the math types.
