## [0.23.0] - 2018-05-02

### Added
- `comment-spacing` ([#198](https://github.com/shyiko/ktlint/pull/198)),  
  `filename` ([#194](https://github.com/shyiko/ktlint/pull/194)) rules.

### Changed
- `kotlin-compiler` version to 1.2.41 (from 1.2.40).

## [0.22.0] - 2018-04-22

### Added
- `--apply-to-idea-project` (as an alternative to (global) `--apply-to-idea`) ([#178](https://github.com/shyiko/ktlint/issues/178)).

- Expected indentation reported by `indent` rule.

### Changed
- Error code returned by `ktlint --format/-F` when some of the errors cannot be auto-corrected (previously it was 0 instead of expected 1) ([#162](https://github.com/shyiko/ktlint/issues/162)). 

## [0.16.1] - 2018-02-27

### Fixed
- Handling of negative number condition in `when` block ([#160](https://github.com/shyiko/ktlint/issues/160)). 

## [0.16.0] - 2018-02-27

### Added

## [0.15.0] - 2018-01-18

### Added

### Changed
- `kotlin-compiler` version to 1.2.20 (from 1.2.0).

## [0.14.0] - 2017-11-30

### Changed
- `continuation_indent_size` to 4 when `--android` profile is used ([android/kotlin-guides#37](https://github.com/android/kotlin-guides/issues/37)). 

### Fixed
- Maven integration ([#117](https://github.com/shyiko/ktlint/issues/117)).

## [0.13.0] - 2017-11-28

### Added
- `no-line-break-before-assignment` ([#105](https://github.com/shyiko/ktlint/issues/105)),  
  `chain-wrapping` ([#23](https://github.com/shyiko/ktlint/issues/23))
(when wrapping chained calls `.`, `?.` and `?:` should be placed on the next line),  
  `range-spacing` (no spaces around range (`..`) operator) rules.
- `--print-ast` CLI option which can be used to dump AST of the file   
(see [README / Creating a ruleset / AST](https://github.com/shyiko/ktlint#ast) for more details)
- `--color` CLI option for colored output (where supported, e.g. --print-ast, default (plain) reporter, etc) 

### Changed
- `.editorconfig` property resolution.   
An explicit `[*.{kt,kts}]` is not required anymore (ktlint looks for sections
containing `*.kt` (or `*.kts`) and will fallback to `[*]` whenever property cannot be found elsewhere).   
Also, a search for .editorconfig will no longer stop on first (closest) `.editorconfig` (unless it contains `root=true`). 
- `max-line-length` rule to assume `max_line_length=100` when `ktlint --android ...` is used  
(per [Android Kotlin Style Guide](https://android.github.io/kotlin-guides/style.html)).  
- `kotlin-compiler` version to 1.2.0 (from 1.1.51).

### Fixed
- `no-empty-class-body` auto-correction at the end of file ([#109](https://github.com/shyiko/ktlint/issues/109)).
- `max-line-length` rule when applied to KDoc ([#112](https://github.com/shyiko/ktlint/issues/112))  
(previously KDoc was subject to `max-line-length` even though regular comments were not).
- Spacing around `=` in @annotation|s (`op-spacing`).
- Spacing around generic type parameters of functions (e.g. `fun <T>f(): T {}` -> `fun <T> f(): T {}`).
- `no-consecutive-blank-lines` not triggering at the end of file (when exactly 2 blank lines are present) ([#108](https://github.com/shyiko/ktlint/issues/108)) 
- `indent` `continuation_indent_size % indent_size != 0` case ([#76](https://github.com/shyiko/ktlint/issues/76))
- `indent` rule skipping first parameter indentation check. 
- `final-newline` rule in the context of kotlin script.
- Git hook (previously files containing space character (among others) in their names were ignored)  
- Exit code when file cannot be linted due to the invalid syntax or internal error.

## [0.12.1] - 2017-11-13

### Fixed
- A conflict between `org.eclipse.aether:aether-*:1.1.0` and `org.eclipse.aether:aether-*:1.0.0.v20140518` ([#100](https://github.com/shyiko/ktlint/issues/100)).

## [0.12.0] - 2017-11-10

### Added
- `--android` (`-a`) CLI option (turns on [Android Kotlin Style Guide](https://android.github.io/kotlin-guides/style.html) compatibility)  
(right now it's used only by `ktlint --apply-to-idea`).

### Changed
- `ktlint --apply-to-idea` to account for `indent_size` & `continuation_indent_size` in `.editorconfig` (if any). 

### Removed
- `ktlint-intellij-idea-integration` binary (deprecated in [0.9.0](#090---2017-07-23)).

### Fixed
- "Unused import" false positive (`component1`..`component5`).

## [0.11.1] - 2017-10-26

### Fixed
- `--reporter`'s `output` handling (previously parent directory was expected to exist) ([#97](https://github.com/shyiko/ktlint/issues/97)).

## [0.11.0] - 2017-10-25

### Added
- `no-blank-line-before-rbrace` rule ([#65](https://github.com/shyiko/ktlint/issues/65)).

### Fixed
- Redundant space inserted between `}` and `::` (curly-spacing).

## [0.10.2] - 2017-10-25 [YANKED]

This release contains changes that were meant for 0.11.0 and so it was retagged as such.

## [0.10.1] - 2017-10-22

### Fixed
- Redundant space inserted between `}` and `[key]`/`(...)` (curly-spacing) ([#91](https://github.com/shyiko/ktlint/issues/91)).

## [0.10.0] - 2017-10-10

### Added

- Git hook to automatically check files for style violations on commit   
(execute `ktlint --install-git-pre-commit-hook` to install).
- Ability to specify multiple reporters   
(output can be controlled with `--reporter=<name>,output=<path/to/file>`) ([#71](https://github.com/shyiko/ktlint/issues/71)).
- Support for `indent_size=unset` (`.editorconfig`) ([#70](https://github.com/shyiko/ktlint/issues/70)).

### Fixed
- `( {` formatting   
(previously both `( {` and `({` were accepted as correct, while only `({` should be) (`curly-spacing` rule) ([#80](https://github.com/shyiko/ktlint/issues/80)).
- `if\nfn {}\nelse` formatting (`curly-spacing` rule). 
- `max_line_length=off` & `max_line_length=unset` handling (`.editorconfig`).

### Changed
- `kotlin-compiler` version to 1.1.51 (from 1.1.3-2).
- `ktlint --apply-to-idea` to include `OPTIMIZE_IMPORTS_ON_THE_FLY=true`. 

## [0.9.2] - 2017-09-01

### Fixed

- `: Unit =` formatting (`: Unit` is no longer dropped when `=` is used) ([#77](https://github.com/shyiko/ktlint/issues/77)). 

## [0.9.1] - 2017-07-30

### Fixed

- `${super.toString()}` linting (`string-template` rule) ([#69](https://github.com/shyiko/ktlint/issues/69)). 

## [0.9.0] - 2017-07-23

### Added

- [Reporter](ktlint-core/src/main/kotlin/com/github/shyiko/ktlint/core/Reporter.kt) API.   
`ktlint` comes with 3 built-in reporters: `plain` (default; `?group_by_file` can be appended to enable grouping by file (shown below)), `json` and `checkstyle`. 
```
$ ktlint --reporter=plain?group_by_file
path/to/file.kt
  1:10 Unused import.
  2:10 Unnecessary "Unit" return type.
path/to/another-file.kt
  1:10 Unnecessary semicolon.
```   
- [string-template](https://ktlint.github.io/#rule-string-template),  
[no-empty-class-body](https://ktlint.github.io/#rule-empty-class-body),  
max-line-length ([#47](https://github.com/shyiko/ktlint/issues/47)),  
final-newline (activated only if `insert_final_newline` is set in `.editorconfig` (under `[*.{kt,kts}]`)) rules.
- `--limit` CLI option (e.g. use `--limit=10` to limit the number of errors to display).
- `--relative` CLI flag which makes `ktlint` output file paths relative to working directory (e.g. `dir/file.kt` instead of
`/home/269/project/dir/file.kt`).

### Changed

- **BREAKING**: JDK version to 1.8 (as a result of upgrading `kotlin-compiler` to 1.1.3-2 (from 1.1.0)).
- File matching (offloaded to [klob](https://github.com/shyiko/klob)).  

### Deprecated

- `--ruleset-repository` and `--ruleset-update` CLI arguments in favour of `--repository` and `--repository-update` 
respectively (`--ruleset-*` will be removed in 1.0.0).  
- `ktlint-intellij-idea-integration` binary   
([Intellij IDEA integration](https://github.com/shyiko/ktlint#option-1-recommended) task is now included in `ktlint` (as `ktlint --apply-to-idea`)).

## [0.8.3] - 2017-06-19

set in `[*{kt,kts}]` section).
- Support for vertically aligned comments (see [NoMultipleSpacesRuleTest.kt](ktlint-ruleset-standard/src/test/kotlin/com/github/shyiko/ktlint/ruleset/standard/NoMultipleSpacesRuleTest.kt)).

### Fixed

- ktlint-ruleset-standard ("no-unit-return" & "modifier-order" where not included).

## [0.7.1] - 2017-05-29

### Fixed

- Triggering of "Unused import" when element is referenced in KDoc(s) only ([#46](https://github.com/shyiko/ktlint/issues/46)).
