We’re happy to announce the Early Access Preview (EAP) build for Kotlin 1.2.70!

**What’s new**

The full changelog is available [here](https://github.com/JetBrains/kotlin/releases/tag/v1.2.70-eap-40).

**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 1.2.x’ and press Check for updates now.

**For Maven or Gradle**  
Add the [https://dl.bintray.com/kotlin/kotlin-eap](https://dl.bintray.com/kotlin/kotlin-eap) repository URL to the list of project repositories. Change the version of Kotlin dependencies (compiler and stdlib) to `1.2.70-eap-40`.

Here is how to do this in Gradle:

```auto
buildscript {
    ext.kotlin_version = '1.2.70-eap-40'

    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:$kotlin_version"
}

```

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.

I guess the serialization plugin does not work yet? As far as I can tell it’s latest version is `0.6.1-SNAPSHOT` which does not seem to be working.

And one more time no love for the Kotlin REPL 😥 The Kotlin REPL is really the worst REPL, I’ve ever used. It is slow and full of bugs. That is sad.

If JetBrains is not willing to improve it, it should probably be killed. In the current state it can only scare potential Kotlin users away.
