+## [0.7.0] - 2025-07-04
+
+### Added
+
+ - cargo-auditable can now use [Cargo's native SBOM precursor](https://doc.rust-lang.org/cargo/reference/unstable.html#sbom) for more accurate dependency trees. This feature is nightly-only as of this writing.
+ - Introduced the `format` field to the encoded data, to let the data consumer know how the dependency tree was obtained (e.g. via the SBOM precursor or not)
+
+### Fixed
+
+ - Procedural macros are no longer erroneously reported as runtime dependencies. If the `format` field is set to 1 higher, they should be assumed to be reported correctly.
