2026.1 is coming — time to check your plugin compatibility

Announcements
1

Hey everyone,
JetBrains IDE 2026.1 releases start rolling out on March 24. Not all products will ship on the same day, we will probably have a release week, but that’s the earliest date you may see them arrive. Now is a good time to make sure your plugin is ready. All APIs are final, no changes from our side besides Critical things blocking the release.

We kindly suggest that you adjust the compatibility range to enable current users to continue enjoying the functionalities of your plugin without any interruptions. Moreover, updating the compatibility settings will also make your plugin discoverable to new users who are exploring the latest version of our IDE.

How to prepare

The simplest approach — and our recommended default — is to drop untilBuild from your build.gradle.kts altogether. When no until-build attribute is specified, your plugin will be compatible with all future builds. You can always restrict it later through the Marketplace versions control if needed.
If you prefer to keep an explicit upper bound, expand it to 261.* or even 262.*.

Try building against 2026.1 EAP

You can test your plugin right now using the EAP snapshot:

dependencies {
    intellijPlatform {
        intellijIdea("261-EAP-SNAPSHOT") {
            useInstaller = false
        }
    }
}

Please also do not forget to update IntelliJ Platform Gradle Plugin, the most recent version is 2.13.1.
Once you upload a new version compatible with 2026.1, please check Plugin Verifier results on the Marketplace!

Help us find API problems

If you run into broken or missing APIs while testing against 2026.1, please let us know. Your reports make the platform better for everyone.

Thank you for everything you build for the JetBrains ecosystem. Wishing you fewer bugs and more users this release season!
