+
+### Added
+- Granular width heuristic options made available for user control [PR #4782](https://github.com/rust-lang/rustfmt/pull/4782). This includes the following:
+ - [`array_width`](https://rust-lang.github.io/rustfmt/?version=v1.4.38&search=#array_width)
+ - [`attr_fn_like_width`](https://rust-lang.github.io/rustfmt/?version=v1.4.38&search=#attr_fn_like_width)
+ - [`chain_width`](https://rust-lang.github.io/rustfmt/?version=v1.4.38&search=#chain_width)
+ - [`fn_call_width`](https://rust-lang.github.io/rustfmt/?version=v1.4.38&search=#fn_call_width)
+ - [`single_line_if_else_max_width`](https://rust-lang.github.io/rustfmt/?version=v1.4.38&search=#single_line_if_else_max_width)
+ - [`struct_lit_width`](https://rust-lang.github.io/rustfmt/?version=v1.4.38&search=#struct_lit_width)
+ - [`struct_variant_width`](https://rust-lang.github.io/rustfmt/?version=v1.4.38&search=#struct_variant_width)
+
+Note this hit the rustup distributions prior to the v1.4.38 release as part of an out-of-cycle updates, but is listed in this version because the feature was not in the other v1.4.37 releases. See also the `use_small_heuristics` section on the configuration site for more information
+[https://rust-lang.github.io/rustfmt/?version=v1.4.38&search=#use_small_heuristics](https://rust-lang.github.io/rustfmt/?version=v1.4.38&search=#use_small_heuristics)
+
+- New `One` variant added to `imports_granularity` configuration option which can be used to reformat all imports into a single use statement [#4669](https://github.com/rust-lang/rustfmt/issues/4669)
+- rustfmt will now skip files that are annotated with `@generated` at the top of the file [#3958](https://github.com/rust-lang/rustfmt/issues/3958)
+ if `format_generated_files` option is set to `false` (by default `@generated` files are formatted)
+- New configuration option `hex_literal_case` that allows user to control the casing utilized for hex literals [PR #4903](https://github.com/rust-lang/rustfmt/pull/4903)
+
+See the section on the configuration site for more information
+https://rust-lang.github.io/rustfmt/?version=v1.4.38&search=#hex_literal_case
+
+- `cargo fmt` now directly supports the `--check` flag, which means it's now possible to run `cargo fmt --check` instead of the more verbose `cargo fmt -- --check` [#3888](https://github.com/rust-lang/rustfmt/issues/3888)

+
+## [1.4.33] 2021-01-27
+
+### Changed
+- `merge_imports` configuration has been deprecated in favor of the new `imports_granularity` option. Any existing usage of `merge_imports` will be automatically mapped to the corresponding value on `imports_granularity` with a warning message printed to encourage users to update their config files.
+
+### Added
+- New `imports_granularity` option has been added which succeeds `merge_imports`. This new option supports several additional variants which allow users to merge imports at different levels (crate or module), and even flatten imports to have a single use statement per item. ([PR #4634](https://github.com/rust-lang/rustfmt/pull/4634), [PR #4639](https://github.com/rust-lang/rustfmt/pull/4639))
+
+See the section on the configuration site for more information
+https://rust-lang.github.io/rustfmt/?version=v1.4.33&search=#imports_granularity
+
+### Fixed
+- Fix erroneous removal of `const` keyword on const trait impl ([#4084](https://github.com/rust-lang/rustfmt/issues/4084))
+- Fix incorrect span usage wit const generics in supertraits ([#4204](https://github.com/rust-lang/rustfmt/issues/4204))
+- Use correct span for const generic params ([#4263](https://github.com/rust-lang/rustfmt/issues/4263))
+- Correct span on const generics to include type bounds ([#4310](https://github.com/rust-lang/rustfmt/issues/4310))
+- Idempotence issue on blocks containing only empty statements ([#4627](https://github.com/rust-lang/rustfmt/issues/4627) and [#3868](https://github.com/rust-lang/rustfmt/issues/3868))
+- Fix issue with semicolon placement on required functions that have a trailing comment that ends in a line-style comment before the semicolon ([#4646](https://github.com/rust-lang/rustfmt/issues/4646))
+- Avoid shared interned cfg_if symbol since rustfmt can re-initialize the rustc_ast globals on multiple inputs ([#4656](https://github.com/rust-lang/rustfmt/issues/4656))

+
+### Fixed
+- Last character in derive no longer erroneously stripped when `indent_style` is overridden to `Visual`. ([#4584](https://github.com/rust-lang/rustfmt/issues/4584))
+- Brace wrapping of closure bodies maintained in cases where the closure has an explicit return type and the body consists of a single expression statement. ([#4577](https://github.com/rust-lang/rustfmt/issues/4577))
+- No more panics on invalid code with `err` and `typeof` types ([#4357](https://github.com/rust-lang/rustfmt/issues/4357), [#4586](https://github.com/rust-lang/rustfmt/issues/4586))

+
+## [1.4.28] 2020-11-29
+
+### Changed
+
+- `rustc-ap-*` crates updated to v691.0.0
+- In the event of an invalid inner attribute on a `cfg_if` condition, rustfmt will now attempt to continue and format the imported modules. Previously rustfmt would emit the parser error about an inner attribute being invalid in this position, but for rustfmt's purposes the invalid attribute doesn't prevent nor impact module formatting.
+
+### Added
+
+- [`group_imports`][group-imports-config-docs] - a new configuration option that allows users to control the strategy used for grouping imports ([#4107](https://github.com/rust-lang/rustfmt/issues/4107))
+
+[group-imports-config-docs]: https://github.com/rust-lang/rustfmt/blob/v1.4.28/Configurations.md#group_imports
+
+### Fixed
+- Formatting of malformed derived attributes is no longer butchered. ([#3898](https://github.com/rust-lang/rustfmt/issues/3898), [#4029](https://github.com/rust-lang/rustfmt/issues/4029), [#4115](https://github.com/rust-lang/rustfmt/issues/4115), [#4545](https://github.com/rust-lang/rustfmt/issues/4545))
+- Correct indentation used in macro branches when `hard_tabs` is enabled. ([#4152](https://github.com/rust-lang/rustfmt/issues/4152))
+- Comments between the visibility modifier and item name are no longer dropped. ([#2781](https://github.com/rust-lang/rustfmt/issues/2781))
+- Comments preceding the assignment operator in type aliases are no longer dropped. ([#4244](https://github.com/rust-lang/rustfmt/issues/4244))
+- Comments between {`&` operator, lifetime, `mut` kw, type} are no longer dropped. ([#4245](https://github.com/rust-lang/rustfmt/issues/4245))
+- Comments between type bounds are no longer dropped. ([#4243](https://github.com/rust-lang/rustfmt/issues/4243))
+- Function headers are no longer dropped on foreign function items. ([#4288](https://github.com/rust-lang/rustfmt/issues/4288))
+- Foreign function blocks are no longer dropped. ([#4313](https://github.com/rust-lang/rustfmt/issues/4313))
+- `where_single_line` is no longer incorrectly applied to multiline function signatures that have no `where` clause. ([#4547](https://github.com/rust-lang/rustfmt/issues/4547))
+- `matches!` expressions with multiple patterns and a destructure pattern are now able to be formatted. ([#4512](https://github.com/rust-lang/rustfmt/issues/4512))

+
+### Fixed
+
+- Leading comments in an extern block are no longer dropped (a bug that exists in v1.4.26). ([#4528](https://github.com/rust-lang/rustfmt/issues/4528))

+
+## [1.4.26] 2020-11-14
+
+### Changed
+
+- Original comment indentation for trailing comments within an `if` is now taken into account when determining the indentation level to use for the trailing comment in formatted code. This does not modify any existing code formatted with rustfmt; it simply gives the programmer discretion to specify whether the comment is associated to the `else` block, or if the trailing comment is just a member of the `if` block. ([#1575](https://github.com/rust-lang/rustfmt/issues/1575), [#4120](https://github.com/rust-lang/rustfmt/issues/4120), [#4506](https://github.com/rust-lang/rustfmt/issues/4506))
+
+In this example the `// else comment` refers to the `else`:
+```rust
+// if comment
+if cond {
+ "if"
+// else comment
+} else {
+ "else"
+}
+```
+
+Whereas in this case the `// continue` comments are members of their respective blocks and do not refer to the `else` below.
+```rust
+if toks.eat_token(Token::Word("modify"))? && toks.eat_token(Token::Word("labels"))? {
+ if toks.eat_token(Token::Colon)? {
+ // ate the token
+ } else if toks.eat_token(Token::Word("to"))? {
+ // optionally eat the colon after to, e.g.:
+ // @rustbot modify labels to: -S-waiting-on-author, +S-waiting-on-review
+ toks.eat_token(Token::Colon)?;
+ } else {
+ // It's okay if there's no to or colon, we can just eat labels
+ // afterwards.
+ }
+ 1 + 2;
+ // continue
+} else if toks.eat_token(Token::Word("label"))? {
+ // continue
+} else {
+ return Ok(None);
+}
+```
+
+### Fixed
+- Formatting of empty blocks with attributes which only contained comments is no longer butchered.([#4475](https://github.com/rust-lang/rustfmt/issues/4475), [#4467](https://github.com/rust-lang/rustfmt/issues/4467), [#4452](https://github.com/rust-lang/rustfmt/issues/4452#issuecomment-705886282), [#4522](https://github.com/rust-lang/rustfmt/issues/4522))
+- Indentation of trailing comments in non-empty extern blocks is now correct. ([#4120](https://github.com/rust-lang/rustfmt/issues/4120#issuecomment-696491872))

+
+### Changed
+
+- Semicolons are no longer automatically inserted on trailing expressions in macro definition arms ([#4507](https://github.com/rust-lang/rustfmt/pull/4507)). This gives the programmer control and discretion over whether there should be semicolons in these scenarios so that potential expansion issues can be avoided.

+
+## [1.4.24] 2020-11-05
+
+### Changed
+
+- Block wrapped match arm bodies containing a single macro call expression are no longer flattened ([#4496](https://github.com/rust-lang/rustfmt/pull/4496)). This allows programmer discretion so that the block wrapping can be preserved in cases where needed to prevent issues in expansion, such as with trailing semicolons, and aligns with updated [Style Guide guidance](https://github.com/rust-dev-tools/fmt-rfcs/blob/master/guide/expressions.md#macro-call-expressions) for such scenarios.
+
+### Fixed
+- Remove useless `deprecated` attribute on a trait impl block in the rustfmt lib, as these now trigger errors ([rust-lang/rust/#78626](https://github.com/rust-lang/rust/pull/78626))
