Early Access Preview for Kotlin 1.3.40 is now open. We begin stabilization process of [new type inference](https://youtrack.jetbrains.com/issue/KT-31507). Now _new type inference_, which has been experimental since 1.3.0, is [enabled by default](https://youtrack.jetbrains.com/issue/KT-30453) in the plugin, but not for compilation. Thus, if code without errors in IDE does not compile, please, report the issue to our [issue tracker](https://kotl.in/issue). The feature can be disabled by unchecking _Enable new type inference algorithm for IDE analysis (experimental)_ checkbox in _Settings_ → _Build, Execution, Deployment_ → _Compiler_ → _Kotlin Compiler_. Additionally, this EAP comes with improvements of Kotlin/JS support in Gradle (such as [NodeJS downloading](https://youtrack.jetbrains.com/issue/KT-30531) and [NodeJS test runner](https://youtrack.jetbrains.com/issue/KT-30528)), [addition of typeOf function](https://youtrack.jetbrains.com/issue/KT-29915), [intrinsification of trimIndent and trimMargin](https://youtrack.jetbrains.com/issue/KT-17755), [support for external nullability annotations](https://youtrack.jetbrains.com/issue/KT-24292) and many small features and bugfixes. Please follow up and try it first! The full changelog is [here](https://github.com/JetBrains/kotlin/releases/tag/v1.3.40-eap-105). ### 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 `1.3.40-eap-105` . Here is how to do this in Gradle: ```groovy buildscript { ext.kotlin_version = '1.3.40-eap-105' 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, as well as whether _new type inference_ is enabled or not. ---
