+## [1.1.1] - 2026-08-17
+
+### Fixed
+
+- Removed the `Ensure no_std` CI job from `.github/workflows/rust.yml`. The crate is std-only (see `SECURITY.md`). It depends on `DynDigest` from the `digest` crate, which needs `Box<dyn DynDigest>` and `std::alloc`. It also depends on `unsigned-varint` with the `std` feature and `subtle`, which declares `extern crate std`. A `no_std` build is not planned for this crate. The `Ensure no_std` job always failed because the dependency stack does not compile for `thumbv6m-none-eabi`.
+
+### Changed
+
+- `multi-codec` pin bumped from `1.1` to `1.2`.
+- `typenum` pin bumped from `1.17` to `1.20`.
+- `proptest` dev-dependency bumped from `1.4` to `1.11`.
