Ktor 3.0.0-beta-2 Help

Ktor releases

Ktor follows Semantic Versioning:

  • Major versions (x.0.0) contain incompatible API changes.

  • Minor versions (x.y.0) provide backward-compatible new functionality.

  • Patch versions (x.y.z) contain backward-compatible fixes.

For each major and minor release, we also ship several preview (EAP) versions for you to try new features before they are released. For more details, see Early Access Program.

Gradle plugin

The Gradle Ktor plugin and the framework are in the same release cycle. You can find all plugin releases on the Gradle Plugin Portal.

IntelliJ Ultimate plugin

The IntelliJ Ktor plugin is released independently of the Ktor framework and uses the same release cycle as IntelliJ IDEA Ultimate.

Update to a new release

The IntelliJ Ktor plugin allows you to migrate your Ktor project to the latest version. You can learn more from the Migrate projects section.
