1.51      millert    49: [This entry is a summary, not a precise list of changes.]
1.46      millert    50:
1.51      millert    51:        Added --csv option to enable processing of comma-separated
                     52:        values inputs.  When --csv is enabled, fields are separated
                     53:        by commas, fields may be quoted with " double quotes, fields
                     54:        may contain embedded newlines.
1.46      millert    55:
1.51      millert    56:        If no explicit separator argument is provided, split() uses
                     57:        the setting of --csv to determine how fields are split.
1.44      millert    58:
1.51      millert    59:        Strings may now contain UTF-8 code points (not necessarily
                     60:        characters).  Functions that operate on characters, like
                     61:        length, substr, index, match, etc., use UTF-8, so the length
                     62:        of a string of 3 emojis is 3, not 12 as it would be if bytes
                     63:        were counted.
1.43      millert    64:
1.51      millert    65:        Regular expressions are processes as UTF-8.

                     68:        to eight hexadecimal digits.  These may appear in strings and
                     69:        regular expressions.
