Jetpack 4.2 SDK Manager

Hello, I’m trying to install Jetpack 4.2.1 with SDK Manager This Jetpack release is not showing up under the Target Operating System drop down menu. Older releases are being shown (3.3.4). Is Jetpack 4.2 supported by SDK Manager 1.6?

I suggest installing the most recent SDKM, and then starting it like this:
sdkmanager --archivedversions

That did the trick. Thanks!
