Did J.K. Rowling write an eighth Harry Potter book after The Tales of Beedle the Bard?

There are seven main "Harry Potter" books. There is no eighth "Harry Potter" book, and there probably won't be one. But there are the three small "school books"; books mentioned in different parts of the main Harry Potter books: namely, the books on Quidditch, on Monsters, and the Tales of Beedle the Bard.
