1198 ### Suggestion Fixes/Improvements
1199
1200 * Fix suggestion of [`unit_arg`] lint, so that it suggest semantic equivalent code
1201   [#4455](https://github.com/rust-lang/rust-clippy/pull/4455)

1212
1213 ### Others
1214
1215 * Introduce a `--rustc` flag to `clippy-driver`, which turns `clippy-driver`
1216   into `rustc` and passes all the given arguments to `rustc`. This is especially
1217   useful for tools that need the `rustc` version Clippy was compiled with,
1218   instead of the Clippy version. E.g. `clippy-driver --rustc --version` will
1219   print the output of `rustc --version`.
1220   [#5178](https://github.com/rust-lang/rust-clippy/pull/5178)
1221 * New issue templates now make it easier to complain if Clippy is too annoying
