+## [0.1.2] - 2026-08-17
+
+### Fixed
+
+- Restored `no_std` build on `thumbv6m-none-eabi` (and other `no_std` targets) by declaring the `half` dependency with `default-features = false` and forwarding the `std`/`alloc` features of `multi-cbor` to `half`. Previously `half = "2.7"` enabled `half`'s default `std` feature unconditionally, so `cargo build --no-default-features --target thumbv6m-none-eabi` linked `std` into a target that does not provide it, failing the `Ensure no_std` CI job with `E0463: can't find crate for std`.
