- Add new `import-grouping` option to group imports with grouping rules specified in configuration ([#403](https://github.com/fourmolu/fourmolu/pull/403))

- Add new `sort-constraints` option to sort constraints alphabetically ([#433](https://github.com/fourmolu/fourmolu/pull/433))

- Add new `sort-derived-classes` option to sort classes in deriving clauses ([#434](https://github.com/fourmolu/fourmolu/pull/434))

- Add new `sort-derived-clauses` option to sort classes deriving clauses ([#434](https://github.com/fourmolu/fourmolu/pull/434))

- Add new `trailing-section-operators` option to disable trailing “section” operators (those that are `infixr 0`, such as `$`) ([#444](https://github.com/fourmolu/fourmolu/pull/444))

- Fix issue where `single-constraint-parens: never` would drop parentheses around implicit parameters ([#446](https://github.com/fourmolu/fourmolu/issues/446))

- Fix indentation for parenthesized expressions that start off the indentation column ([#428](https://github.com/fourmolu/fourmolu/issues/428))
