Hi Jackson,
During our weekly TAM meeting, you asked when you could begin testing the prerelease features. It is usually available a month before a version's actual release. For example, the next release (2022.8.0) is planned for August 25, 2022, so by July 25, you will be able to see the 2022.8.0 version in the prerelease channel.
The list of prerelease features for a given month is posted within the monthly release notes.
Here is the Experience Manager as a Cloud Service monthly release cadence listing future release dates.
