1185 * [`reversed_empty_ranges`]: Avoid linting `N..N` in for loop arguments in
1186   [#5692](https://github.com/rust-lang/rust-clippy/pull/5692)

1193
1194 ### Suggestion Fixes/Improvements
1195
1196 * Fix suggestion of [`unit_arg`] lint, so that it suggest semantic equivalent code
1197   [#4455](https://github.com/rust-lang/rust-clippy/pull/4455)
1198 * Add auto applicable suggestion to [`macro_use_imports`]

1202
1203 * Fix ICE in the `consts` module of Clippy [#5709](https://github.com/rust-lang/rust-clippy/pull/5709)

1208
1209 ### Others
1210
1211 * Introduce a `--rustc` flag to `clippy-driver`, which turns `clippy-driver`
1212   into `rustc` and passes all the given arguments to `rustc`. This is especially
1213   useful for tools that need the `rustc` version Clippy was compiled with,
1214   instead of the Clippy version. E.g. `clippy-driver --rustc --version` will
1215   print the output of `rustc --version`.
1216   [#5178](https://github.com/rust-lang/rust-clippy/pull/5178)
1217 * New issue templates now make it easier to complain if Clippy is too annoying
1218   or not annoying enough! [#5735](https://github.com/rust-lang/rust-clippy/pull/5735)
