• Maven integration (#117).

0.13.0

Added

• no-line-break-before-assignment (#105),
  chain-wrapping (#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 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).
• kotlin-compiler version to 1.2.0 (from 1.1.51).

Fixed

• no-empty-class-body auto-correction at the end of file (#109).
• max-line-length rule when applied to KDoc (#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)
• indent continuation_indent_size % indent_size != 0 case (#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

Fixed

• A conflict between org.eclipse.aether:aether-*:1.1.0 and org.eclipse.aether:aether-*:1.0.0.v20140518 (#100).
