After much procrastination, I am releasing version 1.0.2 of UCSV. This version makes a few small but important changes. In previous versions csvToArray() would insert an empty string into the resulting array when it encountered an empty field. As was suggested by Leon Bambrick, it now instead inserts nulls. Likewise, csvToArray() now converts non-quoted integers and floats into numbers instead of assuming they are strings. arrayToCsv() will convert any null elements into empty fields to complement csvToArray()'s new behavior.
