## [Unreleased]
## [0.5.0] - 2026-09-15
### Changed
- **Breaking:** requires `armature-core` 0.10 (was `0.9`); its types appear in this crate's API, so the requirement change is breaking here and the minor moves. Part of the `armature-core` 0.10 release train.
- Dependencies bumped to their latest releases: `http` 1.4 → 1.5, `lambda_http` 1.2 → 1.3, `lambda_runtime` 1.2 → 1.4, `tokio` 1.52 → 1.53, `tokio` 1.52 → 1.53.
## [0.4.0] - 2026-08-05
### Changed
- **Requires `armature-core` 0.9 (breaking).** The requirement moved `0.8` →
`0.9`. `armature-core 0.9.0` itself moves `armature-h1` across a breaking
0.x boundary; because `armature-core` types appear in this crate's own
public API, the requirement change is breaking here too and the minor moves
with it. Under Cargo's 0.x caret rules the 0.8 and 0.9 types are distinct
and do not unify, so a consumer holding an `armature-core 0.8` type cannot
pass it to this crate. Part of the `armature-core 0.9.0` release train; see
`armature-core`'s CHANGELOG for the publish order.
## [0.3.1] - 2026-08-04
### Fixed
- Requirements on sibling armature crates name a minor instead of `0`. Under
Cargo's 0.x rules `version = "0"` matches any release ever made, and edition
2024 selects the MSRV-aware resolver, so a consumer declaring an older
`rust-version` was handed the oldest version satisfying it — resolving
`armature-core = "0"` on Rust 1.89 produced `armature-core 0.2.3` while an
explicit `armature-core = "0.8"` elsewhere in the same graph pulled 0.8.2.
Two copies of core, and a build failing on symbols the older one lacks. Each
0.x minor in this family is a breaking change, so the requirement now names
one. No API change.
