Amazon is now saying that Professional Ruby On Rails is in stock! I haven’t seen my copies yet, and I suspect Amazon purchases will actually go out next week, but it’s a real page and everything.
The link to purchase is right here.
I’ve also added a [running list of errata and updates](https://docs.google.com/Doc?docid=ah2szrczrmxv_26z j8npddd&hl=en). Check back on that every now and then.
Much more on the book over the next week.
