## [Unreleased]

### Added
## [0.11.0] - 2026-05-20

**Coordinated release:** `echidna` 0.11.0 and `echidna-optim` 0.13.1.
`echidna-optim`'s dep on `echidna` updated from `0.10.0` to `0.11.0`.

Minor bump: adds new public API (simba trait implementations for
`DualVec<F, N>`). No existing types changed and no numerical behaviour
changed.

### Added (echidna)

- **simba traits for `DualVec<F, N>`**: implemented `SimdValue`,
`PrimitiveSimdValue`, `SubsetOf`, `AbsDiffEq`, `RelativeEq`, `UlpsEq`,
`Field`, `ComplexField`, and `RealField`, so `DualVec<F, N>` can be
used as a scalar type inside `nalgebra` matrices and solvers. The
implementations mirror the existing `Dual<F>` simba impls.

- **simba traits for DualVec**: implemented traits `SimdValue`, `PrimitiveSimdValue`, `SubsetOf`, `AbsDiffEq`, `RelativeEq`, `UlpsEq`, `Field`, `ComplexField`, `RealField` for `DualVec<F, N>`.
### Changed (echidna-optim, 0.13.1)

- `echidna` dep updated from `0.10.0` to `0.11.0` (follows the
coordinated release; `echidna-optim`'s public API is unchanged).

Only the latest release of each crate receives security updates.
`echidna` 0.10.0 and `echidna-optim` 0.13.0 are a coordinated release
(`echidna-optim` 0.13.0 depends on `echidna = "0.10.0"`).
`echidna` 0.11.0 and `echidna-optim` 0.13.1 are a coordinated release
(`echidna-optim` 0.13.1 depends on `echidna = "0.11.0"`).

0.10.0 is a minor bump over 0.9.0 driven by the `wgpu` 28 → 29
transitive major; echidna's own public API is unchanged. No new
numerical correctness issues were introduced in 0.9.0 → 0.10.0.
0.11.0 is a minor bump over 0.10.0: it adds simba trait implementations
for `DualVec<F, N>` (new public API for using `DualVec` as a scalar
inside `nalgebra`). echidna's existing types are unchanged. No new
numerical correctness issues were introduced in 0.10.0 → 0.11.0.

### Known issues in unsupported versions

Pre-0.10.0 `echidna` carries the following known numerical correctness
Pre-0.11.0 `echidna` carries the following known numerical correctness
bugs — see the CHANGELOG for per-version detail:

- **0.10.0**: no known numerical correctness bugs; unsupported only
because `echidna` 0.11.0 supersedes it.
- **0.9.0**: no known numerical correctness bugs; unsupported only
because it targets wgpu 28, which is no longer maintained upstream
and received no patches after `wgpu 29.0.0` (2026-03-18).
