* All `sparse` methods now retain provided numerical zeros as structural nonzeros; to
drop numerical zeros, use `dropzeros!` ([#14798], [#15242]).

* `setindex!` methods for sparse matrices and vectors no longer purge allocated entries
on zero assignment. To drop stored entries from sparse matrices and vectors, use
`Base.SparseArrays.dropstored!` ([#17404]).

* New `foreach` function for calling a function on every element of a collection when
the results are not needed ([#13774]).
