What a way to remind you:

Warning to Restart

Well, it may not be as obvious as it is in IE or Mozilla browsers, There is a new icon that let me to investigate further.

new icon

When I clicked on it, the menu showed:

Chrome Menu

Notice the Update Google Chrome !

And that is what led me to read the error about Restart to Apply Update because it has not crashed or been restarted lately

After a restart the icon went back to ‘normal’.
