“We’re happy to announce the beginning of the public Early Access Preview program for Kotlin. The program gives you a chance to try out new versions of Kotlin before they are officially released to the public, and to give your feedback.
Right now the Early Access Preview builds for Kotlin 1.0 Release Candidate are available.
To use the new builds from Maven or Gradle: add https://dl.bintray.com/kotlin/kotlin-eap/19 as a repository to your project. The EAP build version is 1.0.0-rc-1017
To install the EAP version of the IntelliJ IDEA plugin: open Tools | Kotlin | Configure Kotlin Plugin Updates in the main menu, select the Early Access Preview channel, press the Check for updates now button
New features and changes (draft): https://gist.github.com/abreslav/f60fc0de060e7ed721c9104
If you’re a library maintainer, please don’t publish updates of your library compiled with the EAP build to your main Maven repository. This is necessary to ensure that users don’t run into unexpected compatbility issues.(edited)
As usual, please report issues to YouTrack: http://youtrack.jetbrains.com/issues/KT7”
