These functions are now deprecated in favor of alternative versions that return a vector of strings rather than a table of strings. Deprecated functions: - split: use split_string instead. - split1: use split_string1 instead. - split_all: use split_string_all instead. - split_n: use split_string_n instead. - cat_string_array: see join_string_vec instead. - cat_string_array_n: see join_string_vec instead. - join_string_array: see join_string_vec instead. - sort_string_array: use sort instead instead. - find_ip_addresses: use extract_ip_addresses instead. Changed functions: - has_valid_octets: uses a string_vec parameter instead of string_array. Addresses BIT-924, BIT-757.
