Anyone else having this issue?:

==> cloudi_x_cowlib (compile)

/home/vagrant/cloudi-1.5.1/src/external/cloudi_x_cowlib/src/cloudi_x_cow_multipart.erl:350: crypto:rand_bytes/1 is deprecated and will be removed in a future release; use crypto:strong_rand_bytes/1

On Erlang/OTP 19

This problem went away for me when I downgraded Erlang/OTP to 17.5 in case anyone else has an issue

This warning is just saying that this will be a problem when Erlang/OTP 20 is released and the function call disappears.  It isn't a reason to not use Erlang/OTP 19.  The cowlib source code is tied to the cowboy source code, which is at the 1.0 release in CloudI, due to cowboy 2.0 not being considered stable yet.
