Microsoft have update the builds of Windows 10 19H1 and 19H2. Windows users on the Release Ring with the May 2019 Update (19H1) get build 18362.385 and Windows Insiders on the Release Preview ring get 18363.385. The update is delivered by KB4517211 but Microsoft do not actually say what has changed in the update.
19H2 is due very soon, maybe Microsoft are planning on releasing the update at their October 2nd event.
UPDATE to clear up the release/release preview confusion.
