At least, I think it's the 7th. Got it from Amazon a couple of months ago, and on the copyright page the numbers show "10 9 8 7". To my understanding that's 7th printing. I question it because BA mentioned on the blog recently that it just went into the 6th printing (he mentioned this after I bought it, here).

Regardless, I found some typos while reading the book. I only see two of them previously mentioned (and both are still there).

pg 16, three lines from bottom - "telwl" should be "tell"

pg 80, 2nd paragraph from bottom, first line - "causes" should be "cause"

pg 173, sentence before break - should be "it was a triumph" instead of "it was triumph"

pg 259, last line of paragraph about Carl Sagan: "can be easily be applied" - should be either "can easily be applied" or "can be easily applied"

pg 213, end of last full paragraph: "is none" should be "are none". I see that's been mentioned several times, and there is disagreement, but there is a rule here: pronouns must agree with the quantity of the noun they replace. "None" is a pronoun that can be singular or plural (in contrast to common belief that it can only be singular; this belief is ahistorical) but in this case is plural (as "none" is referring to "fundamental principles").

Great book in spite of a few typos (and trust me, I find a lot more in most books; I also don't usually bother to notify anyone). I look forward to reading the next BA book!
