1.51 millert 100: -----------------------------------------------------------------
1.48 millert 101:
1.51 millert 102: [This entry is a summary, not a precise list of changes.]
1.46 millert 103:
1.51 millert 104: Added --csv option to enable processing of comma-separated
105: values inputs. When --csv is enabled, fields are separated
106: by commas, fields may be quoted with " double quotes, fields
107: may contain embedded newlines.
1.46 millert 108:
1.51 millert 109: If no explicit separator argument is provided, split() uses
110: the setting of --csv to determine how fields are split.
1.44 millert 111:
1.51 millert 112: Strings may now contain UTF-8 code points (not necessarily
113: characters). Functions that operate on characters, like
114: length, substr, index, match, etc., use UTF-8, so the length
115: of a string of 3 emojis is 3, not 12 as it would be if bytes
116: were counted.
1.43 millert 117:
1.58 ! millert 118: Regular expressions are processed as UTF-8.
1.6 kstailey 119:
1.51 millert 120: Unicode literals can be written as \u followed by one
121: to eight hexadecimal digits. These may appear in strings and
122: regular expressions.
