It's at:

It's not that huge, by modern Web standards — 169K. It only covers stuff since the What's New page went live on eyrie-productions.com, though, so since late 1999. (I have another page tracking the release dates of EPU's first decade releases, mostly determined from their Usenet posting dates.)

My usual caveat about "What Previously Was New" is that it's updated entirely manually, so isn't necessarily up to date at any given time (though it is right now).

Also, I got distracted in the 2013-2014 time frame (getting married will do that to you), so I missed scraping any entries between 2013/09/10 and 2014/06/16. I'm pretty sure I reconstructed all the fiction released in that period, but I'm may be missing any art or audiobooks, as well as Gryphon's clever phrasing of the announcements. Any web caches or backups from that period would be welcome.
