Catalina 10.15 and SU 2019.3

Perhaps I missed it, but what has happened to to 2019.3? It was mentioned in a post three weeks ago as having been released but still no formal announcement that I have seen, nor any link to update within SU itself.

Read the Release Notes …

Note:: This link is in the rightside nav bar for the SketchUp online User Guide.
It always leads to the current version’s release notes.

Always comes after a bit of time to let things settle.

These in application notices are rolled out progressively so as not to overload the servers.

How do I get the update? When I select Sketchup / Check for update it tells me that I have the most recent version. That does not help much does it?
Is there any link??
