Their website says 2014. Amazon says 2018. But definitely not 2024, unless I am missing something.

Direct link is https://htdp.org/2024-11-6/Book/index.html which says "Released on Wednesday, November 6th, 2024 7:36:10pm"

I think this is the 2024 digital release of the 2014/2018 physical publication.

I believe it was edited on the release date given.
