We are happy to announce the 1.3.60 Early Access Preview opening.
In this EAP we have some improvements in Kotlin/JS test infrastructure:
- Browser test task is failed if there were some fails in launching of Karma [KT-31663](https://youtrack.jetbrains.com/issue/KT-31663)
- Standard output (log, warn, error) of tests (browser and nodejs both) now captured to Gradle test output [KT-32073](https://youtrack.jetbrains.com/issue/KT-32073)
- Filter tests for browser and nodejs via `--tests` CLI argument [KT-32216](https://youtrack.jetbrains.com/issue/KT-32216)
- Support source maps for Gradle stack traces [KT-31478](https://youtrack.jetbrains.com/issue/KT-31478)
Also experimental stdlib function `typeOf` presented in 1.3.40 for Kotlin/JVM is supported for Kotlin/JS now.
In Kotlin/Native we’ve added support for XCode 11 and some new compilation targets (see [changelog](https://github.com/JetBrains/kotlin-native/blob/671da8181cb729dca449cc597dc6c89d4f429b73/CHANGELOG.md) for additional information). Also there are some performance improvements.
In IDEA plugin there is new feature available: in-project scratch files, aka _Worksheets._
Note that since 1.3.60 minimal supported gradle version is 4.9.
Other improvements and fixes beyond these highlights for the upcoming 1.3.60 release can be found in the [full changelog](https://github.com/JetBrains/kotlin/blob/f4c170f1565ed425a27c7cd874dc9cc575931462/ChangeLog.md) and [separately](https://github.com/JetBrains/kotlin-native/blob/671da8181cb729dca449cc597dc6c89d4f429b73/CHANGELOG.md) for Kotlin Native.
Please note that compatible Native libraries have not been shipped yet. We are aiming to release it soon.
## 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.X’ 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 `1.3.60-eap-143`.
Here is how to do this in Gradle:
```groovy
buildscript {
ext.kotlin_version = '1.3.60-eap-143'
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 versions.

Should I be able to use the serialization plugin with this? My build.gradle file works with 1.3.50, but if I change the plugin version, I get an error.
```
buildscript {
ext.kotlin_version = "1.3.60-eap-76"
// ext.kotlin_version = "1.3.50"
repositories {
maven { url 'https://dl.bintray.com/kotlin/kotlin-eap' }
jcenter()
}
dependencies {
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath("org.jetbrains.kotlin:kotlin-serialization:$kotlin_version")
}
}
plugins {
id 'org.jetbrains.kotlin.multiplatform' version '1.3.50'
// id 'org.jetbrains.kotlin.plugin.serialization' version '1.3.50'
id 'org.jetbrains.kotlin.plugin.serialization' version "1.3.60-eap-76"
}
```

Not sure about this version, but in my experience it takes a bit longer for eap builds of the serialization library to be released, if there is a release for it at all.

The [github page](https://github.com/Kotlin/kotlinx.serialization) shows an EAP version (0.14.0-1.3.60-eap-76), but I’ve tried putting that string in various places in my build.gradle file and nothing works.

Use `0.14.0-1.3.60-eap-76` as the version for the serialization dependency. Since it’s still in alpha, it’s version might not be the same as the kotlin version.

It seems like you need to add `https://kotlin.bintray.com/kotlinx` to your maven depository list. This is based on [JFrog Distribution: Get your software to where it needs to be -- ASAP!](https://bintray.com/kotlin/kotlinx/kotlinx.serialization.runtime/0.14.0-1.3.60-eap-76), haven’t tested it.

I just added that to the buildscript section and the main section. Still get the error.
```
buildscript {
..
repositories {
maven { url 'https://dl.bintray.com/kotlin/kotlin-eap' }
maven { url 'https://kotlin.bintray.com/kotlinx' }
jcenter()
}

I’m using the eap while trying out the new Jetpack Compose android library. I’m having issues with I believe kapt and dagger 2 in the same project. Are there any known issues with kapt or any work around any has seen?

Hi,
Since you are using Gradle’s `plugins` block I believe that you need to add `kotlin-eap` bintray repository to [Gradle plugin repositories](https://docs.gradle.org/current/userguide/plugins.html#sec:custom_plugin_repositories). Version of **plugin** must be the same as compiler one, `1.3.40-eap-76`, while version of **runtime library** is, indeed, `0.14.0-1.3.60-eap-76`.

Kapt is currently not usable with Jetpack Compose, see [https://youtrack.jetbrains.com/issue/KT-34583](https://youtrack.jetbrains.com/issue/KT-34583).
