Can't locate Timeline in PackageManager (a11)

Release notes mention that Timeline has been moved into built-in packages, but I can't see it anywhere on the package list (show preview packages enabled). Anyone else has this problem?

 

If you create a new project, you should see it. However, we currently have an issue with projects created in earlier versions of 2019.1. For these projects, make sure to add this line to your project manifest.json:

Code (CSharp):

1.     "com.unity.timeline": "0.0.0-builtin",
2.  

 

Thanks! This should probably be in upgrade notes.

 

I'm also having issues with Cinemachine being unable to see Timeline namespace.

Library\PackageCache\com.unity.cinemachine@2.2.7\Runtime\Timeline\CinemachineTrack.cs(14,6): error CS0246: The type or namespace name 'TrackColor' could not be found (are you missing a using directive or an assembly reference?)
Library\PackageCache\com.unity.cinemachine@2.2.7\Runtime\Timeline\CinemachineTrack.cs(15,37): error CS0246: The type or namespace name 'TrackAsset' could not be found (are you missing a using directive or an assembly reference?)...

... and similar errors for a whole bunch of other Timeline related classes.

Btw, I did delete the Asset Store version of Cinemachine before installing it via PackageManager. I've uninstalled and reinstalled it a couple times now but no dice.
