I don't think there's anything more recent.
I've read most of the "recent" books on training. If you want something that gives you a solid framework from which you can modify and expand, definitely check out RCTM. The rest have useful information, but it's often hard to figure out how to put it all together.
For general paradigm, 9 out of 10 Climbers Make the Same Mistakes by Dave MacLeod is excellent.
For a broad survey and additional non-climbing-wall exercises, Training for Climbing by Horst has a rather extensive additional exercises section.
For skill, Rock Climbing Technique by John Kettle is good.
For summiting big mountains and not worrying about top-line climbing skill, Training for the New Alpinism.
The biggest problem in training right now is an abundance of information and a proliferation of "bro science". Step back, consider what you are really training FOR, and then target the skills and strengths you'll need to accomplish that goal.
EDIT: if you want super recent, follow Camp 4 Human Performance (@c4hp) on Instagram and read some of the papers he posts. It'll be very interesting, but you'll have a harder time coming up with a "plan". The information is really helpful after you've got a frameworked plan to work with.
