Ktor releases
Ktor follows semantic versioning:
Major versions (1.0, 2.0, and so on) can contain incompatible API changes.
Minor versions (2.1, 2.2, and so on) can provide backward-compatible functionality.
Patch versions (2.2.1, 2.2.2, and so on) can add backward-compatible fixes.
You can find all Ktor releases on GitHub: Releases.
For each major and minor release, we also ship several preview (EAP) versions for you to try new features before they are released. See Early Access Program for details.

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.
