CHANGELOG

1.1-M03 (EAP-3)

New language features

  • KT-2964 Underscores in integer literals (see KEEP-54)
  • KT-3824 Underscore in lambda for unused parameters (see KEEP-56)
  • KT-2783 Allow to skip some components in a multi-declaration

Compiler

Coroutines related issues

  • Make fields for storing lambda parameters non-final (as they get assigned within invoke call)
  • KT-14719 Make initial continuation able to be resumed with exception
  • KT-14636 Coroutine fields should not be volatile
  • KT-14718 Validate label value of coroutine in case of no suspension points

Typealises related issues

  • KT-13514 Type inference doesn't work with generic typealiases
  • KT-13837 Error “Type alias expands to T, which is not a class, an interface, or an object” should also appear for local type aliases
  • KT-14307 Local recursive type alias should be an error
  • KT-14400 Compiler Error IllegalStateException: kotlin.NotImplementedError when anonymous object inherits from typealias
  • KT-14377 Expected error: Modifier ‘companion’ is not applicable to ‘typealias’
  • KT-14498 typealias allows to circumvent variance annotations
  • KT-14641 An exception while processing a nested type alias access after a dot

Various issues

  • KT-550 Properties without initializer but with get must infer type from getter
  • KT-8816 Generate Kotlin parameter names in the same form as expected for Java 8 reflection
  • KT-10569 Cannot iterate over values of an enum class when it is used as a generic parameter (see KEEP-37)
  • KT-11551 limited scope for dsl writers (see KEEP-38)
  • KT-13557 VerifyError with delegated local variable used in object expression
  • KT-13890 IllegalAccessError when invoking protected method with default arguments
  • KT-14012 Back-end (JVM) Internal error every first compilation after the source code change
  • KT-14201 UnsupportedOperationException: Don't know how to generate outer expression for anonymous object with invoke and non-trivial closure
  • KT-14318 Repeated annotations resulting from type alias expansion should be reported
  • KT-14347 Report UNUSED_PARAMETER/VARIABLE on named unused lambda parameters/destructuring entries
  • KT-14352 @SinceKotlin is not taken into account for companion object member referenced via type alias
  • KT-14357 Try-catch used in false condition generates CompilationException
  • KT-14502 Prohibit irrelevant modifiers and annotations on destructured parameters in lambda
  • KT-14692 Change resolution scope for componentX in lambda parameters
  • KT-14824 Back-end (JVM) Internal error: Couldn't inline method call ‘get’ into local final fun StorageComponentContainer.(): kotlin.Unit

JS

Feature support

  • KT-6985 Support Exceptions in JS
  • KT-13574 JS: support coroutines
  • KT-14422 JS: Support destructuring in lambda parameters
  • KT-14507 JS: allow to skip some components in a multi-declaration

Library updates

  • KT-14637 JS: Missing ArrayList.ensureCapacity

Other issues

  • KT-2328 js: kotlin exceptions must inherit Error
  • KT-5537 Drop Cloneable in JS
  • KT-7014 JS: generate code which more friendly to js tools (minifier, optimizer, linter etc)
  • KT-8019 JS: no stackTrace in exception subclasses
  • KT-10911 JS: Throwable properties aren't supported well
  • KT-13912 JS: Compiler NPE at JsSourceGenerationVisitor. Lambda with empty [if] block passed to inline function
  • KT-14535 JS: Broken modification of captured variables defined by a destructuring declaration

Standard Library

  • KT-2084 Common API should be available without referring to java.* packages

    Now those common types, which are supported on all platforms, are available in kotlin.* packages, and are imported by default. These include:

    • ArrayList, HashSet, LinkedHashSet, HashMap, LinkedHashMap in kotlin.collections
    • Appendable and StringBuilder in kotlin.text
    • Comparator in kotlin.comparisons On JVM these are just typealiases of the good old types from java.util and java.lang

  • KT-13554 Introduce bitwise operations and/or/xor/inv for Byte and Short

  • KT-13582 New platform-agnostic extensions for arrays: contentEquals to compare arrays' content for equality, contentHashCode to get hashcode of array's content, and contentToString to get the string representation of array elements.

  • KT-14510 Generic constraints of Array.flatten signature were relaxed a bit to make it just usable.

  • KT-14789 Provide KotlinVersion class, which allows to get the current version of the standard library and compare it with some other KotlinVersion value.

IDE

  • KT-14409 Incorrect “Variable can be declared immutable” inspection for local delegated variable
  • KT-14431 Create quick-fix on UNUSED_PARAMETER/VARIABLE when it can be replaced with one underscore
  • KT-14794 Add /Specify type/Remove explicit type intentions for property with getters if type can be inferred
