-#### New `dir-name` attribute
-
-Some of the paths generated under `target/` have resulted in a de-facto "build
-protocol", where `cargo` is invoked as a part of a larger project build. So, to
-preserve the existing behavior, there is also a new attribute `dir-name`, which
-when left unspecified, defaults to the name of the profile. For example:
-
-```toml
-[profile.release-lto]
-inherits = "release"
-dir-name = "lto"  # Emits to target/lto instead of target/release-lto
-lto = true
-```
