Books published in the first quarter of 2015?

What books on logic (mathematical or philosophical logic) and/or philosophy of maths have been published in the first quarter of 2015? There’s John Burgess’s Rigor and Structure which I have started blogging about here. But what else has appeared so far this year?

Not that I’m lacking things to read! But I’d like to know what I’m missing, and I’m probably not alone. So maybe you would like to share any recommendations of recent titles which might be of interest to readers of Logic Matters?
