Unity editor minimum compatible version requirements in changelogs or package documentation

I just spent 45 minutes attempting to update from [UI Toolkit 1.0.0-preview.14] to [UI Toolkit 1.0.0-preview.15]. My editor version is 2020.3.6f1. The Package Manager does not list any requirements for a Unity version, and similarly clicking the 'View changelog' or 'View documentation' links from within the Package Manager still keep any requirements completely in the dark.
Only after searching the forums was I able to find this thread which states:
"Minimum versions compatible

• 2020.3.14f1"

https://forum.unity.com/threads/ui-toolkit-latest-version-1-0-0-preview-15.941420/#post-7405298

Though, adding further confusion from the link at the end of the post stating this requirement for the migration guide:
"The steps should be valid for editor versions 2020.3.xxx"
https://forum.unity.com/threads/ui-toolkit-migration-guide.1138621/#post-7405538

Overall it would be nice to have these requirements up front within the Package Manager to avoid having to dig around through the forums.
