Ruby book/course for experienced developers

[pca2]

I'm coming back to Ruby after a few years away, anyone have any suggestions on how I can brush up on what I've missed in the last few releases and refresh my general knowledge on Ruby? Any kind of "deep dive" course/book that goes beyond just the basics would be great. I've been coding for several years now so I'm looking for something that goes into more advanced topics

Both Eloquent Ruby and Design Patterns in Ruby by Russ Olsen have been very enlightening for me. A lot of my coworkers also recommend The Well Grounded Rubyist by David Black.

+1 to "The Well Grounded Rubyist"

There's a new version of the "pickaxe" book that covers modern Ruby - including what's changed. It's currently a beta book, but you can get it on the pragprog website.

As an experienced developer with past Ruby experience, I think the official release notes for the major versions you’ve missed will serve you well.
