Sorry, but I won't be coming out with an updated Early Access Release for my Solr 4.x Deep Dive e-book today. I was doing great during the summer since there were so few distractions, but after Labor Day the distractions have just kept piling on.
I actually have been doing a little work on the book, reading code, contriving examples, and running these examples, primarily for the remaining portions of the Solr Admin API. I've even written a few pages, but all of the distractions have sapped my focus.
That said, I think the distractions have peaked (except for the upcoming Twitter IPO!!), so that I may be able to regain more focus on writing this weekend.
The current Early Access Release, #7, is still available for purchase and download on Lulu.com:
Thanks for your support and patience for this ambitious project.
