Recommendations for books on boundary layer Meteorology?
Is there any particular aspect of boundary layer meteorology? Or just something general?
NOTE: I have not read all of these nor do I know anyone who has read these, but judging by the year published or level of detail, these may serve whatever purpose you want. I found these mostly by Googling. I recommend looking at the preview offered in each website.

Turbulence by John Wyngaard- published in 2010
Fundamentals of Boundary-Layer Meteorology by Xuhui Lee was published in 2017, but from the brief look inside, I don't see a large difference from Stull or Arya.
Atmospheric Boundary Layer Integrating Air Chemistry and Land Interactions (2015)
Turbulence and Dispersion in the Planetary Boundary Layer By Francesco Tampieri · 2016
