  38 * [`reversed_empty_ranges`]: Avoid linting `N..N` in for loop arguments in
  39   [#5692](https://github.com/rust-lang/rust-clippy/pull/5692)

  47 ### Suggestion Fixes/Improvements
  48
  49 * Fix suggestion of [`unit_arg`] lint, so that it suggest semantic equivalent code
  50   [#4455](https://github.com/rust-lang/rust-clippy/pull/4455)

  54 ### ICE Fixes
  55
  56 * Fix ICE in the `consts` module of Clippy [#5709](https://github.com/rust-lang/rust-clippy/pull/5709)
  57
  58 ### Documentation Improvements
  59
  60 * Improve code examples across multiple lints [#5664](https://github.com/rust-lang/rust-clippy/pull/5664)
  61
  62 ### Others
  63
  64 * Introduce a `--rustc` flag to `clippy-driver`, which turns `clippy-driver`
  65   into `rustc` and passes all the given arguments to `rustc`. This is especially
  66   useful for tools that need the `rustc` version Clippy was compiled with,
  67   instead of the Clippy version. E.g. `clippy-driver --rustc --version` will
  68   print the output of `rustc --version`.
  69   [#5178](https://github.com/rust-lang/rust-clippy/pull/5178)
  70 * New issue templates now make it easier to complain if Clippy is too annoying
  71   or not annoying enough! [#5735](https://github.com/rust-lang/rust-clippy/pull/5735)
