## [Unreleased]
## [1.5.0] 2022-06-13
### Changed
- 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)
### Fixed
- Fixes issue where wrapped strings would be incorrectly indented in macro defs when `format_strings` was enabled [#4036](https://github.com/rust-lang/rustfmt/issues/4036)
- Remove duplicate imports when `imports_granularity` is set to `Item` [#4725](https://github.com/rust-lang/rustfmt/issues/4725)
- Properly handle stdin input containing an inner skip attribute [#5368](https://github.com/rust-lang/rustfmt/issues/5368)
- Maintain attributes on imports when `imports_granularity` is set to `Item` [#5030](https://github.com/rust-lang/rustfmt/issues/5030)
- 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)
- 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)
- 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)
- Fixed various `error[internal]: left behind trailing whitespace"` issues:
- 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)
- 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)
- 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)
- Fix various module resolution issues preventing rustfmt from finding modules that should be formatted:
- Handle external mods imported via external->inline load hierarchy [#5063](https://github.com/rust-lang/rustfmt/issues/5063)
- Resolve sub modules of integration tests [#5119](https://github.com/rust-lang/rustfmt/issues/5119)
- 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)
- 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)
- Fix various issues related to type aliases:
- Prevent rustfmt from adding `= impl` to associated types defined in macro bodies [#4823](https://github.com/rust-lang/rustfmt/issues/4823)
- 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)
- Prevent rustfmt from adding an `impl Trait` definition into types [#5086](https://github.com/rust-lang/rustfmt/issues/5086)
- 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)
- 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)
- Don't format files annotated with inner `#![rustfmt::skip]` attribute [PR #5094](https://github.com/rust-lang/rustfmt/pull/5094)
- 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)
- 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)
- 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)
- 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)
- Backport json emitter and stdin changes [PR #5054](https://github.com/rust-lang/rustfmt/pull/5054)
- Make `--check` work when running rustfmt with input from stdin [PR #3896](https://github.com/rust-lang/rustfmt/pull/3896)
- Fix `--check` with the `--files-with-diff` flag [PR #3910](https://github.com/rust-lang/rustfmt/pull/3910)
- Produce valid JSON when using the JSON emitter [PR #3953](https://github.com/rust-lang/rustfmt/pull/3953)
- Fix newlines in JSON output [PR #4262](https://github.com/rust-lang/rustfmt/pull/4262)
- Use `<stdin>` when emitting stdin as filename [PR #4298](https://github.com/rust-lang/rustfmt/pull/4298)
- 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)
- 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)
- 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)
- 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)
- 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)
- 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)
- 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)
- Properly wrap and format long markdown block quotes when `wrap_comments=true` [#5157](https://github.com/rust-lang/rustfmt/issues/5157)
- 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)
- 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)
- 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)
- 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)
- 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)
- 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)
- Retain trailing `;` when rewriting macro calls in extern blocks. For example, `extern "C" { x!(-); }`[#5281](https://github.com/rust-lang/rustfmt/issues/5281)
- 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)
### Added
- 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)
- 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)
### Removed
- Removed unstable, nightly-only config option `report_todo` [#5101](https://github.com/rust-lang/rustfmt/issues/5101)
- Removed unstable, nightly-only config option `report_fixme` [#5102](https://github.com/rust-lang/rustfmt/issues/5102)
- Removed unstable, nightly-only config option `license_template_path` [#5103](https://github.com/rust-lang/rustfmt/issues/5103)
### Misc
- 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)
### Install/Download Options
- **rustup (nightly)** - *pending*
