This morning, I saw that the zephyr release 0.51.0 was released.
So this morning when I restarted Arduino again it showed me that there were boards to update.
So I clicked on the update for zephyr.
When it completed, I went to tools->Boards and the zephyr was no long shown (It showed my install) in the
hardware directory still.
On closer inspection, I did find that a different board was installed: Arduino Uno Q
When I back to the board manager it did show me that there is Arduino Zephyr Boards (Beta) that I could
install, which I did.
