 # Changelog
 
+## Cargo 1.56 (2021-10-21)
+[cebef295...HEAD](https://github.com/rust-lang/cargo/compare/cebef295...HEAD)
+
+### Added
+
+- Build scripts can now pass additional linker arguments for binaries or all
+  linkable targets. [docs](https://doc.rust-lang.org/nightly/cargo/reference/build-scripts.html#outputs-of-the-build-script)
+  [#9557](https://github.com/rust-lang/cargo/pull/9557)
+- Added support for the `-p` flag for `cargo publish` to publish a specific
+  package in a workspace. `cargo package` also now supports `-p` and
+  `--workspace`.
+  [#9559](https://github.com/rust-lang/cargo/pull/9559)
+
+### Changed
+
+- Doc tests now support the `-q` flag to show terse test output.
+  [#9730](https://github.com/rust-lang/cargo/pull/9730)
+- `features` used in a `[replace]` table now issues a warning, as they are ignored.
+  [#9681](https://github.com/rust-lang/cargo/pull/9681)
+- Changed so that only `wasm32-unknown-emscripten` executables are built
+  without a hash in the filename. Previously it was all `wasm32` targets.
+  Additionally, all `apple` binaries are now built with a hash in the
+  filename. This allows multiple copies to be cached at once, and matches the
+  behavior on other platforms (except `msvc`).
