Apart from Windows 10 Build 20226 which is in channel Dev, Microsoft was released Windows 10 build 19042.546 in the Beta and Release channels Preview.
The update is released as a cumulative update and does not include new features. Microsoft seems to be wrapping it up version 20H2 of Windows 10 before it hits the stable channel and becomes available to everyone.
The patch comes with two fixes. The change log states the following
Fixed an issue preventing a device from entering Modern Standby.
Fixed a reliability issue in Microsoft Edge that occurs when you open multiple windows or tabs.
The update is available to Insiders who have chosen to receive updates from the Beta and Release Preview channels. The corrections are expected to be released for users of version 20H1 in the form of an optional update.
Version 20:2 am of Windows 10 is its successor May 2020 Update, or version 2004 released in May 2020. Windows 20 version 2H10 will be a minor, smaller update that focuses mainly on selected performance, and quality improvements.
