  • Coroutines (async/await, generators) (proposal)

    Current limitations:

    • for some cases type inference is not supported yet
    • limited IDE support
    • allowed only one handleResult function: design
    • handling finally blocks is not supported: issue

  • Bound callable references (proposal)

  • Type aliases (proposal)

    Current limitations:

    • type alias constructors for inner classes are not supported yet
    • annotations on type alias are not supported yet
    • limited IDE support

  • Local delegated properties (proposal)

  • JDK dependent built-in classes (proposal)

  • Sealed class inheritors in the same file (proposal)

  • Allow base classes for data classes (proposal)

Scripting

  • Implement support for Script Definition Template
    and related functionality, except the following parts:
    • automatic script templates discovery is not implemented
    • @file:ScriptTemplate annotation is not supported
    • the parameters javaHome and scripts from KotlinScriptExternalDependencies are not used yet
  • Implement support for custom template-based scripts in IDEA: resolving, completion and navigation to symbols from script classpath and sources
  • Implement GradleScriptTemplateProvider extension that supplies a script template if gradle with
    kotlin script support is used in the project

    This inspection reports dangerous operations inside constructors including:

    • Accessing non-final property in constructor
    • Calling non-final function in constructor
    • Using 'this' as function argument in constructor of non-final class
Issues fixed
  • KT-12389 Do not exit from REPL when toString() of user class throws an exception
