We ship different types of releases:
- Feature releases (1.x) that bring major changes in the language.
- Incremental releases (1.x.y) that are shipped between feature releases and include updates in the tooling, performance improvements, and bug fixes.
- Bug fix releases (1.x.yz) that include bug fixes for incremental releases.
For example, for the feature release 1.9 we had several incremental releases including 1.9.10 and 1.9.20. For 1.9.20, we had additional bug fix releases – 1.9.22, 1.9.23, and 1.9.24.
For each incremental and feature release, we also ship several preview (EAP) versions for you to try new features before they are released. See Early Access Preview for details.

Starting from IntelliJ IDEA 2023.3 and Android Studio Iguana (2023.2.1) Canary 15, the Kotlin plugin is automatically updated. All you need to do is update the Kotlin version in your projects.
{type="note"}
IntelliJ IDEA and Android Studio suggest updating to a new release once it is out. When you accept the suggestion, it automatically updates the Kotlin plugin to the new version. You can check the Kotlin version in Tools | Kotlin | Configure Kotlin Plugin Updates.
If you have projects created with earlier Kotlin versions, change the Kotlin version in your projects and update kotlinx libraries if necessary.
If you are migrating to the new feature release, Kotlin plugin's migration tools will help you with the migration.
The IDE support for the latest version of the language is available for the following versions of IntelliJ IDEA and Android Studio:
- IntelliJ IDEA:
- Latest stable
- Previous stable
- Early access versions
- Android Studio:
- Latest released version
- Early access versions
Learn more about the latest Kotlin-related updates in IntelliJ IDEA in the Kotlin section of the What's new in IntelliJ IDEA page.
