There are no updates because the work got cease and desisted.
Copyright owners of one or more of the depicted characters (not all are pre-1923, especially Ms. Poppins) complained of copyright infringement and threatened to sue if the author didn't take down the site. The author wrote back, claiming that the work was a Fair Use criticism of the characters and that mirrors would pop up anyway. They settled on the author leaving it up but not making new pages and not mentioning the settlement.
- Why would they care if he mentioned the settlement? If anything, they'd want people to realise they didn't approve of copyright infringement. Given what happened to Casey and Andy before this, it seems more likely he just got bored of it.
