 Rust 1.29.0 added the `cargo fix` subcommand to automatically fix some simple compiler warnings. Since then, the number of warnings that can be fixed automatically continues to steadily increase. In addition, support for automatically fixing some simple Clippy warnings has also been added.
 
-Starting from Rust 1.69.0, Cargo will suggest running `cargo fix` or `cargo clippy --fix` when it detects some warnings are automatically fixable.
+In order to draw more attention to these increased capabilities, Cargo will now suggest running `cargo fix` or `cargo clippy --fix` when it detects warnings that are automatically fixable:
+
+    warning: unused import: `std::hash::Hash`
+     --> src/main.rs:1:5
+      |
+    1 | use std::hash::Hash;
+      |     ^^^^^^^^^^^^^^^
+      |
+      = note: `#[warn(unused_imports)]` on by default
+    
+    warning: `foo` (bin "foo") generated 1 warning (run `cargo fix --bin "foo"` to apply 1 suggestion)
+
+Note that the full Cargo invocation shown above is only necessary if you want to precisely apply fixes to a single crate. If you want to apply fixes to all the default members of a workspace, then a simple `cargo fix` (with no additional arguments) will suffice.
