 Description   

In addition to the 3 bullets currently listed in
https://docs.mongodb.com/manual/release-notes/3.2-compatibility/#aggregation-compatibility-changes

Consider adding a fourth bullet around the more forgiving nature of the $unwind stage as now it does not error on non-array operands. It now treats a non-array operand as a single element array.

It is true this is documented here: https://docs.mongodb.com/manual/reference/operator/aggregation/unwind/#non-array-field-path

But it may make sense to collate all of these changes into the compatibility section.
