+## v1.1.2
 
 * Fix [off-by-one error](https://github.com/the-lean-crate/cargo-diet/issues/1) when printing the diff
 * Improve [error output](https://github.com/the-lean-crate/cargo-diet/issues/2) when `cargo package` fails
 
-#### v1.1.1
+## v1.1.1
 
 * Reduce file-size of produced binaries
 
-#### v1.1.0
+## v1.1.0
 
 * Add the --package-size-limit flag to allow exiting with a non-zero code if the estimated
   crate package size exceeds the given value. This is particularly useful on CI, which can
   leverage the pre-built binaries to get quick access to `cargo diet` without building it
   from source.
