this is just a theme idea which helps announcing new changes in a more exciting way:
it would be great if admins can put the link to new updates in a theme, and a gift or update icon appears next to the search icon for users.
two examples which show my purpose better:
Trello new stuff
they are a one-time clickable update icon, and when a user clicks on them, he is guided toward the complete news. so far this can be done with a simple icon added next to the menu.
but the good thing about these icons is that it gets activated when some new features or discount or … is released in the program, and as one clicks on this, it disappears!
