### What’s new

The changelog compared to [1.3-RC3](https://github.com/JetBrains/kotlin/releases/v1.3-rc3) is available [here](https://github.com/JetBrains/kotlin/releases/v1.3-rc4).

### How to get the EAP build

#### For IntelliJ IDEA

You can configure _Early Access Preview_ channel in _Tools_ → _Kotlin_ → _Configure Kotlin Plugin Updates_. Change the update channel to ‘Early Access Preview 1.3’ and press _Check for updates now_.

#### For Maven or Gradle

Add the `https://dl.bintray.com/kotlin/kotlin-eap` repository URL to the list of project repositories, and set `kotlin_version` to `1.3.0-rc-190`. Here is how to do this in Gradle:

```auto
buildscript {
    ext.kotlin_version = '1.3.0-rc-190'

    repositories {
        maven { url 'https://dl.bintray.com/kotlin/kotlin-eap' }
        mavenCentral()
    }

    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

apply plugin: "kotlin"

repositories {
    maven { url 'https://dl.bintray.com/kotlin/kotlin-eap' }
    mavenCentral()
}

dependencies {
    compile "org.jetbrains.kotlin:kotlin-stdlib"
}

```

Please provide feedback and report issues to our [issue tracker](https://kotl.in/issue). Please don’t forget to specify your IDE/build system Kotlin plugin versions.

The follow code works in Kotlin 1.2.71 but gets error in 1.3.0-rc-190 (Unsupported [suspend operator “getValue”]), will this feature present in 1.3?

```kotlin
suspend operator fun Any.getValue(
        thisRef: Any?,
        property: KProperty<*>
): Any = TODO()

```

It is pretty useful for async lazy.

No, they’ve been forbidden in 1.3 since they are not fully supported at the moment ([KT-24866](https://youtrack.jetbrains.com/issue/KT-24866))

I’m sorry, it is a pretty feature.  
Should I open a new issue about it? I wish to put my vote on it.
