There's a bonus story feature in this game called the Book of Tales.  It's a fun way to learn more about the characters and experience holiday themed content; the first being a Halloween episode that was made last October.  0.7 focuses on the second event which is Spring Themed.  It's not as crucial to the story as other updates but it's got some video game inspired costumes and a fun side story.

Also some other core gameplay changes but I'd check the changelog for those if you're interested!
