Rethinking page linking led to a new update.
As you may have discovered, previously and inconveniently, changing a page name (or URL title) meant broken teaser links. To avoid broken teaser links, you had to remember to change all related teaser links. Not anymore! Now you can simply select the page to which you want to link, and it will "magically" re-set all related teaser links for you!
The screenshot below shows the backend interface for linking a teaser to a page.
