Version 2.8.0 2020-04-10
========================

Changes
-------
(New) Tests for auspost, codablock, composite, dotcode, general, telepen,
  upcean, all output formats
- QR, Han Xin, Grid Matrix: the multi byte compaction schemes (ex: Kanji)
  are used by some decoders as codepage information (Ex: GB2312) and output
  may be translated to UTF-8. This may destroy the data in a not controlable
  manner.
  In consequence, multibyte compaction schemes are disabled by default.
  The new option --fullmultibyte (option_3 = ZINT_FULL_MULTIBYTE) enables this
  optimisation.
- Add new symbology "Ultra Code" with the ability to output colour codes.

  - Codablock: data 0x1a..0x1f caused segfault
  - Dotcode: overrun in binary mode, overrun in codeword_array buffer
      Correct encoding of HT/FS/GS/RS when shifting to code set B
  - empty or unreadable input file
  - telepen: buffer overflow
  - EANUCC: buffer overflow on multiple + (multiple extension bars)
  - Maxicode: index overrun on numeric compaction
  - CodeOne: Simple i indexing not sp + i in C1_ASCII numeric latch loop.
  - Aztec: free memory
- Ticket 183: Databar stacked separator correction
- Ticket 182: Output bitmap type was char, where some targets assigned 0
  if pixel colour >127 (e.g. negative). API change to use unsigned char.
- HanXin: wrong codepage, gb2312 instead gb18030.
- PDF417: corrected alloced sizes to max characters
- Ticket 189: FNC1 encodation fixed (FLG(0) missing after FLG(n))
