• Add binary compatibility validator - #2131, by @mateuszkwiecinski

• Replace kotlin public data classes with Poko compiler plugin generated ones - #2136, by @mateuszkwiecinski
  As a part of public API stabilization, data classes are no longer used in the public API. As of that, functions like copy() or componentN() (used for destructuring declarations) are not available anymore.

• Promote experimental rules - #2218, by @paul-dingemans
  The rules below have been promoted to non-experimental rules:

  • blank-line-before-declaration
  • context-receiver-wrapping
  • discouraged-comment-location
  • enum-wrapping
  • function-naming
  • function-signature
  • if-else-bracing
  • multiline-expression-wrapping
  • if-else-wrapping
  • no-blank-line-in-list
  • no-consecutive-comments
  • no-empty-file
  • no-empty-first-line-in-class-body
  • no-single-line-block-comment
  • parameter-list-spacing
  • property-naming
  • statement-wrapping
  • string-template-indent
  • try-catch-finally-spacing
  • type-argument-list-spacing
  • type-parameter-list-spacing
  • unnecessary-parentheses-before-trailing-lambda

• Fix statement-wrapping and align rule classes - #2178, by @paul-dingemans
  Rule class MultilineExpressionWrapping has been renamed to MultilineExpressionWrappingRule. Rule class StatementWrapping has been renamed to StatementWrappingRule. RULE_ID constants below are moved to a different Java class at compile time. Each rule provided by Ktlint is to be accompanied by a RULE_ID constant that can be used in the VisitorModifier.RunAfter. Filenames did not comply with standard that it should end with Rule suffix.

  RULE ID	Old Java class name	New Java class name
  FUNCTION_EXPRESSION_BODY_RULE_ID	FunctionExpressionBodyKt	FunctionExpressionBodyRuleKt
  FUNCTION_LITERAL_RULE_ID	FunctionLiteralKt	FunctionLiteralRuleKt
  MULTILINE_EXPRESSION_WRAPPING_RULE_ID	MultilineExpressionWrappingKt	MultilineExpressionWrappingRuleKt
  NO_BLANK_LINE_IN_LIST_RULE_ID	NoBlankLineInListKt	NoBlankLineInListRuleKt
  NO_EMPTY_FILE_RULE_ID	(not applicable)	NoEmptyFileRuleKt

• Update to Kotlin 1.9 & remove TreeCopyHandler extension - #2113, by @paul-dingemans
  Class org.jetbrains.kotlin.com.intellij.treeCopyHandler is no longer registered as extension point for the compiler as this is not supported in Kotlin 1.9. Please test your custom rules. In case of unexpected exceptions during formatting of code, see #2044 for possible remediation.

🆕 Features

• Define EditorConfigOverride for dynamically loaded ruleset - #2194, by @paul-dingemans
  The EditorConfigOverride parameter of the KtlintRuleEngine can be defined using the factory method EditorConfigOverride.from(vararg properties: Pair<EditorConfigProperty<*>, *>). This requires the EditorConfigProperty's to be available at compile time. Some common EditorConfigProperty's are defined in ktlint-rule-engine-core which is loaded as transitive dependency of ktlint-rule-engine and as of that are available at compile.
  If an EditorConfigProperty is defined in a Rule that is only provided via a runtime dependency, it gets a bit more complicated. The ktlint-api-consumer example has now been updated to show how the EditorConfigProperty can be retrieved from the Rule.
