How do I work out what version of IntelliJ a particular version of Android Studio is based on? I had a look in the "About Android Studio" window and all I see is the following information:

The first three groups of numbers of the Android Studio build are the version of the IntelliJ Platform build that the Android Studio build is based on: 213.7172.25. The first two digits indicate the year: 2021. The third digit indicates the release number: 3. So it is based on the 2021.3 version of the IntelliJ Platform.

The Android Studio version name (e.g. "2021.3.1") encodes what version of IntelliJ it was based on, as follows:

<Year of IntelliJ Version>.<IntelliJ major version>.<Studio major version>

As described in the "New versioning scheme - Android Studio" section of the Announcing Android Studio Arctic Fox (2020.3.1) & Android Gradle plugin 7.0 Android Developers Blog post:

• The first two number groups represent the version of the final IntellIj platform that a particular Android Studio release is based on (earlier canaries may still be on the earlier version). For this release, this is 2020.3.
• The third number group represents the Studio major version, starting at 1 and incrementing by one for every major release.

So "2021.3.1", for example, encodes that this version of Android Studio is based on the "2021.3" version of the IntelliJ platform.
