In docs > conf.py, there is a variable master_doc = "index". Not that it matters, but should we change this for main_doc for consistency, or it's unrelated? Other than that, I didn't find remaining mentions of master that should be changed in xclim code.

Good catch. I didn't bother changing this since I figured that this was a sphinx target (and it is). Luckily, it also seems like the Sphinx developers have migrated away from this nomenclature as well. Will update this field now.
