A small, but relevant update. With this version of DataFrames.jl we also re-export a new version of Missings.jl, which introduces `passmissing` function. We would welcome a feedback on this functionality (as it might eventually be considered for inclusion into Julia Base).

The `passmissing` function wraps any Julia function `f` (typically `missing` “unaware”) accepting positional arguments so that if any of them is `missing` it returns `missing` and otherwise calls `f` with the passed arguments. Here is an example showing you the difference:

```julia
julia> string(missing, " ", missing)
"missing missing"

julia> passmissing(string)(missing, " ", missing)
missing

```
