Review of "maximum on dictionary returns max key instead of max val" #14672

[fpmenninger]

--
The original poster of #14672 asked for a function that would find the key of the minimum (or maximum) of the values in a dictionary.

In the last post before the issue was closed
JeffBezanson commented on Sep 14, 2017 commented:
findmax and indmax now do what the OP requests. If you want the maximum value, maximum(values(d))works. From there, I think it's simplest for maximum just to operate on iterators like it does now, so the behavior with pairs is strange but it's what falls out. I think the only possible further change from there is to change how Dicts iterate.

However while true for v0.7, this is not the case for v0.6

d = Dict('a'=>4, 'b'=>3, 'c'=>2, 'd'=>1)
findmin(d) # gives (1,'d') in v0.7, but ('a'=>4, 2) in v0.6

Right, this is a breaking change that was made in 0.7 (master).

Will there be something similar to a deprecation notice in either version?
