97 "Arimo, Arial, sans-serif" (all others)
98 (was "Helvetica, sans-serif" for both)

100 quiet zone settings respected exactly, and centring of HRT (if any) now
101 relative to linear part of symbol only rather than whole symbol

141 embedding of font in vector output - currently only for SVG output
142 - GUI: use "OCRB" font for EAN/UPC and "Arimo" for all others (was "Helvetica"

723
724 Changes
725 -------
726 (New) Tests for auspost, codablock, composite, dotcode, general, telepen,
727 upcean, all output formats
728 - QR, Han Xin, Grid Matrix: the multi byte compaction schemes (ex: Kanji)
729 are used by some decoders as codepage information (Ex: GB2312) and output
730 may be translated to UTF-8. This may destroy the data in a not controlable
731 manner.
732 In consequence, multibyte compaction schemes are disabled by default.
733 The new option --fullmultibyte (option_3 = ZINT_FULL_MULTIBYTE) enables this
734 optimisation.
