9 - Simplify the rustfmt help text by eliding the full path to the rustfmt binary path from the usage string when running `rustfmt --help` [#5214](https://github.com/rust-lang/rustfmt/issues/5214)
13 - Remove duplicate imports when `imports_granularity` is set to `Item` [#4725](https://github.com/rust-lang/rustfmt/issues/4725)
14 - Properly handle stdin input containing an inner skip attribute [#5368](https://github.com/rust-lang/rustfmt/issues/5368)
15 - Maintain attributes on imports when `imports_granularity` is set to `Item` [#5030](https://github.com/rust-lang/rustfmt/issues/5030)
16 - Format empty trait definitions as a single line when both `empty_item_single_line` is enabled and `brace_style` is set to `AlwaysNextLine` [#5047](https://github.com/rust-lang/rustfmt/issues/5047)
17 - Don't change granularity of imports containing comments with `imports_granularity` if doing so could lose or misplace those comments [#5311](https://github.com/rust-lang/rustfmt/pull/5311)
18 - Prevent rustfmt from removing trailing comments at the end of files annotated with inner `#![rustfmt::skip]` attributes [#5033](https://github.com/rust-lang/rustfmt/issues/5033)
19 - Fixed various `error[internal]: left behind trailing whitespace"` issues:
20 - Remove trailing whitespace when formatting a where clause who's bounds have an empty right hand side [#5012](https://github.com/rust-lang/rustfmt/issues/5012) [#4850](https://github.com/rust-lang/rustfmt/issues/4850)
21 - Prevent rustfmt from adding an empty comment line when rewriting markdown lists at the start of doc comments. This issue was triggered when `wrap_comments=true` [#5088](https://github.com/rust-lang/rustfmt/issues/5088)
22 - Prevent adding a block indented newline before a function parameter with a complex type that was formatted over multiple lines [#5125](https://github.com/rust-lang/rustfmt/issues/5125)
23 - Fix various module resolution issues preventing rustfmt from finding modules that should be formatted:
24 - Handle external mods imported via external->inline load hierarchy [#5063](https://github.com/rust-lang/rustfmt/issues/5063)
25 - Resolve sub modules of integration tests [#5119](https://github.com/rust-lang/rustfmt/issues/5119)
26 - Module resolution will fallback to the current search directory if a relative directory search results in a `FileNotFound` error [#5198](https://github.com/rust-lang/rustfmt/issues/5198)
27 - Give users a clearer error message when resolving a module who's file path is ambiguous (e.g `x.rs` and `x/mod.rs`). Before users were given a `File not found` error message which was confusing [#5167](https://github.com/rust-lang/rustfmt/issues/5167)
28 - Fix various issues related to type aliases:
29 - Prevent rustfmt from adding `= impl` to associated types defined in macro bodies [#4823](https://github.com/rust-lang/rustfmt/issues/4823)
30 - Properly block indent type alias impl traits (TAITs) that wrap to the next line when `version=Two` is set. Before any trait bounds that wrapped to the next line would not be indented [#5027](https://github.com/rust-lang/rustfmt/issues/5027)
31 - Prevent rustfmt from adding an `impl Trait` definition into types [#5086](https://github.com/rust-lang/rustfmt/issues/5086)
32 - Fix cases where `normalize_comments=true` would de-normalizes some comments by changing inline comments into block comments [#4909](https://github.com/rust-lang/rustfmt/issues/4909)
33 - Prevent rustfmt from wrapping the content of markdown [reference-style links](https://www.markdownguide.org/basic-syntax/#reference-style-links) in doc comments [#5095](https://github.com/rust-lang/rustfmt/issues/5095) [#4933](https://github.com/rust-lang/rustfmt/issues/4933)
34 - Don't format files annotated with inner `#![rustfmt::skip]` attribute [PR #5094](https://github.com/rust-lang/rustfmt/pull/5094)
35 - Prevent duplicate comma when struct pattern ends with `..` and `trailing_comma=Always`. For example, `let Foo { a, .. } = b;` would become `let Foo { a,, .. } = b;` [#5066](https://github.com/rust-lang/rustfmt/issues/5066)
36 - Fix the order of `static` and `async` keywords when rewriting static async closures. The correct order is `static` and then `async` (e.g `static async || {}`) [#5149](https://github.com/rust-lang/rustfmt/issues/5149)
37 - Retain the fully qualified path segment when rewriting struct literals in expression position. Now `<Struct as Trait>::Type` is not rewritten as `Trait::Type` [#5151](https://github.com/rust-lang/rustfmt/issues/5151)
38 - Do not remove match arm braces from a match arm with a single `ast::ExprKind::Block` that has leading attributes. Removing the braces could lead to code that does not compile. Now rustfmt will leave the outer `{}` in place when formatting `=> {#[allow(unsafe_code)]unsafe {}}` [#4109](https://github.com/rust-lang/rustfmt/issues/4109)
39 - Backport json emitter and stdin changes [PR #5054](https://github.com/rust-lang/rustfmt/pull/5054)
40 - Make `--check` work when running rustfmt with input from stdin [PR #3896](https://github.com/rust-lang/rustfmt/pull/3896)
41 - Fix `--check` with the `--files-with-diff` flag [PR #3910](https://github.com/rust-lang/rustfmt/pull/3910)
42 - Produce valid JSON when using the JSON emitter [PR #3953](https://github.com/rust-lang/rustfmt/pull/3953)
43 - Fix newlines in JSON output [PR #4262](https://github.com/rust-lang/rustfmt/pull/4262)
44 - Use `<stdin>` when emitting stdin as filename [PR #4298](https://github.com/rust-lang/rustfmt/pull/4298)
45 - Always generate some output when formatting `@generated` files via stdin even when `format_generated_files=false`. Not producing output caused rust-analyzer to delete the file content [rust-lang/rust-analyzer](https://github.com/rust-lang/rust-analyzer/issues/11285) [#5172](https://github.com/rust-lang/rustfmt/issues/5172)
46 - Properly block indent multi-line comments in empty struct definitions. Previously, only the first comment line would be block indented. All other comment lines would be aligned with the struct definition [#4854](https://github.com/rust-lang/rustfmt/issues/4854)
47 - Prevent rustfmt from wrapping a comment at a byte position inside a non-ascii character when `wrap_comments=true`. This prevents rustfmt from panicking when breaking on the invalid position [#5023](https://github.com/rust-lang/rustfmt/issues/5023)
48 - Prevent rustfmt from removing commented out trailing separators (e.g commas) when rewriting lists. For example, remove the comma from a comment like this `// ...,` would lead to a scenario where the entire list could not be rewritten because the content of the comment changed [#5042](https://github.com/rust-lang/rustfmt/issues/5042)
49 - Fix panic when `import_granularity` was set to `Module`, `One`, or `Crate` and the import use declaration contained an alias `use crate a::b as b1` [#5131](https://github.com/rust-lang/rustfmt/issues/5131)
50 - Add a newline between generic parameters and their doc comments to prevent the generic parameters from being merged into their doc comments [#5122](https://github.com/rust-lang/rustfmt/issues/5122)
51 - Fixes indentation issue where string literals manually broken with line continuation characters (`\`) would be incorrectly indented in macro definitions when setting `format_strings=true`[#4036](https://github.com/rust-lang/rustfmt/issues/4036)
52 - Properly wrap and format long markdown block quotes when `wrap_comments=true` [#5157](https://github.com/rust-lang/rustfmt/issues/5157)
53 - Prevent rustfmt from wrapping markdown headers even when `wrap_comments=true`. Wrapping the markdown headers would prevent them from being properly rendered with rustdoc [#5238](https://github.com/rust-lang/rustfmt/issues/5238)
54 - Prevent rustfmt from removing commas between struct fields when those fields were also separated by an empty line [#4791](https://github.com/rust-lang/rustfmt/issues/4791) [#4928](https://github.com/rust-lang/rustfmt/issues/4928)
55 - Fix compiler error caused when formatting imports with `imports_granularity=Module` and a path containing `self`. Given the following import `use crate::lexer::{self, tokens::TokenData};`, rustfmt would transform the `self` import into `use crate::lexer::self;`. Now rustfmt produces `use crate::lexer::{self};` [#4681](https://github.com/rust-lang/rustfmt/issues/4681)
56 - Prevent rustfmt from breaking long type links in doc comments on namespace qualifiers (`::`) when `wrap_comments=true`. Breaking these long type links over multiple lines prevented them from being properly rendered in rustdoc [#5260](https://github.com/rust-lang/rustfmt/issues/5260)
57 - Correctly find the start of struct bodies after any generic `const` parameters. Naively searching for an opening `{` lead to issues since generic `const` parameters are also defined with `{}` (e.g. `struct Example<const N: usize = { 1048576 }> {}`) [#5273](https://github.com/rust-lang/rustfmt/issues/5273)
58 - Prevent rustfmt from merging derives when using inner or outer `rustfmt::skip::attributes` attributes. For example, `#[rustfmt::skip::attributes(derive)]` [#5270](https://github.com/rust-lang/rustfmt/issues/5270)
59 - Retain trailing `;` when rewriting macro calls in extern blocks. For example, `extern "C" { x!(-); }`[#5281](https://github.com/rust-lang/rustfmt/issues/5281)
60 - Add a newline when formatting struct fields preceded by both doc comments and inline comments to prevent the field from being merged into the inline comment. This was not an issue when a struct was preceded by just a doc comment or just an inline comment [#5215](https://github.com/rust-lang/rustfmt/issues/5215)
64 - Added `One` as a new [group_imports](https://rust-lang.github.io/rustfmt/?version=v1.4.38&search=#group_imports) option to create a single group for all imports [PR #4966](https://github.com/rust-lang/rustfmt/pull/4966)
65 - Add [short_array_element_width_threshold](https://rust-lang.github.io/rustfmt/?version=v1.4.38&search=#short_array_element_width_threshold) config option to give users more control over when `Mixed` list formatting is used [PR #5228](https://github.com/rust-lang/rustfmt/pull/5228)
69 - Removed unstable, nightly-only config option `report_todo` [#5101](https://github.com/rust-lang/rustfmt/issues/5101)
70 - Removed unstable, nightly-only config option `report_fixme` [#5102](https://github.com/rust-lang/rustfmt/issues/5102)
71 - Removed unstable, nightly-only config option `license_template_path` [#5103](https://github.com/rust-lang/rustfmt/issues/5103)
75 - Improved performance when formatting large and deeply nested expression trees, often found in generated code, which have many expressions that exceed `max_width` [#5128](https://github.com/rust-lang/rustfmt/issues/5128), [#4867](https://github.com/rust-lang/rustfmt/issues/4867), [#4476](https://github.com/rust-lang/rustfmt/issues/4476), [#5139](https://github.com/rust-lang/rustfmt/pull/5139)

110 - **Note that this bug fix may cause observable formatting changes in cases where code had been formatted with prior versions of rustfmt that contained the bug**
111 - Fixed bug where rustfmt would drop parameter attributes if they were too long in certain cases [#4579](https://github.com/rust-lang/rustfmt/issues/4579)
112 - Resolved idempotency issue with extern body elements [#4963](https://github.com/rust-lang/rustfmt/issues/4963)

123 - Granular width heuristic options made available for user control [PR #4782](https://github.com/rust-lang/rustfmt/pull/4782). This includes the following:
124 - [`array_width`](https://rust-lang.github.io/rustfmt/?version=v1.4.38&search=#array_width)
125 - [`attr_fn_like_width`](https://rust-lang.github.io/rustfmt/?version=v1.4.38&search=#attr_fn_like_width)

136 - 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)
137 if `format_generated_files` option is set to `false` (by default `@generated` files are formatted)
138 - 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)

201 ## [1.4.33] 2021-01-27
204 - `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.
207 - 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))

277 ## [1.4.28] 2020-11-29
281 - `rustc-ap-*` crates updated to v691.0.0
282 - 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.
286 - [`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))
288 [group-imports-config-docs]: https://github.com/rust-lang/rustfmt/blob/v1.4.28/Configurations.md#group_imports
291 - 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))
292 - Correct indentation used in macro branches when `hard_tabs` is enabled. ([#4152](https://github.com/rust-lang/rustfmt/issues/4152))
293 - Comments between the visibility modifier and item name are no longer dropped. ([#2781](https://github.com/rust-lang/rustfmt/issues/2781))
294 - Comments preceding the assignment operator in type aliases are no longer dropped. ([#4244](https://github.com/rust-lang/rustfmt/issues/4244))
295 - Comments between {`&` operator, lifetime, `mut` kw, type} are no longer dropped. ([#4245](https://github.com/rust-lang/rustfmt/issues/4245))
296 - Comments between type bounds are no longer dropped. ([#4243](https://github.com/rust-lang/rustfmt/issues/4243))
297 - Function headers are no longer dropped on foreign function items. ([#4288](https://github.com/rust-lang/rustfmt/issues/4288))
298 - Foreign function blocks are no longer dropped. ([#4313](https://github.com/rust-lang/rustfmt/issues/4313))
299 - `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))
300 - `matches!` expressions with multiple patterns and a destructure pattern are now able to be formatted. ([#4512](https://github.com/rust-lang/rustfmt/issues/4512))

320 ## [1.4.26] 2020-11-14
324 - 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))
326 In this example the `// else comment` refers to the `else`:
337 Whereas in this case the `// continue` comments are members of their respective blocks and do not refer to the `else` below.
339 if toks.eat_token(Token::Word("modify"))? && toks.eat_token(Token::Word("labels"))? {
340 if toks.eat_token(Token::Colon)? {
342 } else if toks.eat_token(Token::Word("to"))? {
343 // optionally eat the colon after to, e.g.:
344 // @rustbot modify labels to: -S-waiting-on-author, +S-waiting-on-review
345 toks.eat_token(Token::Colon)?;
347 // It's okay if there's no to or colon, we can just eat labels
352 } else if toks.eat_token(Token::Word("label"))? {
360 - 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))
361 - Indentation of trailing comments in non-empty extern blocks is now correct. ([#4120](https://github.com/rust-lang/rustfmt/issues/4120#issuecomment-696491872))

369 ## [1.4.25] 2020-11-10
373 - 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.

381 ## [1.4.24] 2020-11-05
385 - 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.
388 - 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))
