Ready for review.

That's a lot of work, thank you! I was just surprised that you made a change scheduled for 0.17. Also, there is a conflict with one file, could you please fix it?

[emmanuelle]

This was planned for 0.17 so why do it now?

I think maybe it was a misclassification in the TODO list.

The warning states 0.16

@emmanuelle actually, it was in Other section.

Originally, the warning was introduced here -ef07903 (#2854), before 0.14.0. It looks like there is no mistake, and the change was correctly scheduled for 0.16.0 (2 major releases: deprecation in 0.15, removal in 0.16).
