Ah, my mistake.  Since the "compatibility" check of the notebook was
suggesting changing all of my Random[] calls, I assumed incorrectly
that Random[] would no longer work.  In fact Random[] backward
compatibility has been maintained.

The "compatibility" check should provide more information about its
suggestions when they aren't really compatibility issues, but rather
recommended performance improvements.

That's a good solution to the Needs[] error.  I have updated my
package to do that, removed the Developer` from the BeginPackage
header, and now it works.  Thanks!
