I see it's available in Safari Books (for those who have a subscription.) Wikipedia says, "the second edition was released in April 2013." Looks like that's just before version 5.3 came out, and there have been 13 releases since then. However, there are mostly 5 star reviews on Amazon, including ones from 2019, so it sounds like it's still worth reading.
