 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.
 Bugs
 ----

      Correct encoding of HT/FS/GS/RS when shifting to code set B
  - empty or unreadable input file

  - 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))

 Update front end to Qt5. Output to EMF and TIF. Copy to clipboard. Update
 to latest draft of DMRE. Usual bugfixes.
 Version 2.6.1:
 Library bugfixes: EDIFACT unlatch in Data Matrix, Add UPNQR, Improved Aztec
 data compression, Detect Code 128 data too long, Make error codes consistent.

 Bugfixes for TIF and EMF output and escape character handling.
 Version 2.6.4:
 Fixed bugs: EMF output, maxicode plot/content
 Datamatrix DMRE updated to the ISO/IEC29158 version. This is incompatible in the way,
 that the old -vers numbers for DMRE are re-assigned.
 The separator of GS1-datamatrix may be switched from FNC1 to GS.
 GS1 field length check AI 8009 and 7230 to 7239 currected.
 Version 2.6.5:

 Ticket 164: crash due to call of svg_plot withnull vector
 Ticket 119: Crash on bullseye raster drawing
 qtzint: Micro-QR version option choice corrected (+1 missing).
 Datamatrix: code corruption when ECI was encoded and base256 encoding was automatically chosen.
 Version 2.6.7 2019-10-07:
 Changes:
 Ticket 127: Allow to code ECI 3 if explicitly given for debug purposes.
 ***Incompatible change**
 "--eci 3" now leads to included ECI information.
 "--eci 0" may now be used to not include any ECI information.
 The default of the parameter changed from 3 to 0.
 Fixed bugs:
 Ticket 146, 165: fix wrong encoding of RSS composite codes
 Version 2.7.0 2019-12-05:
 Changes:
 - Automatic height option added to qzint
 - DotCode in line with new specification
 - New GS1 AIs 7240, 235, 417, 7040, 8026, updated checks for 7007, 8008

 Fixed bugs:
 - Many improvements in composite codes
 - SVG output corrected for messages containing "<" and "&".
 - GS1-128 and RSS may only be used with GS1 contents

 Version 2.7.1 2020-02-01:
 Changes:
 - QR encoding optimized to get smaller code matrix results
 - PDF417: remove obsolete codeword number option in qzint.
  Option removed in qtzint.

  from the manual. This material may be found elsewhere.
 - MAC homebrew remark added to the documentation
 - Correct cmake file to match BSD-3-clause licence
 Bugs:
 - Correct uninitialized warning in gridmatrix.call
 - do not export internal functions
 - raster painting of UPC-A bound check
 - pdf417 documentation corrected: change flag -security to -secure
 - Dot Code encoding ECI number corrected

 - Datamatrix: corrected possible buffer overrun in 3 characters to 2 byte
  encodings.
 - In 2.7.0 removed interface "ZBarcode_Render" still declared
 - vc6 make was missing (trivial) resource.h
 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.
 Bugs:
 - Ticket 181 penetration test found many bugs:
  - Auspost: null bytes in content caused segfault
  - 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))
 - PCX format: added missing bytes_per_line if bitmap width is odd.
 Version 2.9.0 2020-07-31:

 - New option "-separator=" for zint to specify the separator height of stacked
  symbologies.

 v0.5 - Added Australia Post 4-State Barcodes and Pharmacode (1 and 2 track).
 4-state codes now draw with correct height/width ratio. 28/2/2007
 v0.6 - Added Plessey and some derivative codes (EAN-128, Code 128 subset B,
 Auspost Reply, Auspost Routing, Auspost Redirect, ITF-14). Tidied up code
 again: separated symbologies into more files and put all lookup tables into
 arrays (much reducing the amount of code, especially for Code 39e and Code 93).

 colour. User variable whitespace and border width. Box option. Fixed EAN add-on
 bug. Added whitespace and height options. Project name changed to Zint to avoid
 conflict with extant trade name. Added escape character input. 1/4/2007

 completes the list of features I originally wanted (plus a few more), hence
 skip to version 1.0. 20/4/2007

 one User Manual document. 13/6/2007
 v1.4 - Added NVE-18 support. Corrected some problems with compilation and input
 verification. Command line option handling now uses getopt(), and all the
 switches have changed. Added –font option. 20/6/2007
 v1.5 - Pulled everything together to make an API. Corrected errors with EAN-13,
 PDF417 and LOGMARS. Added EPS output. Added QR Code support using libqrencode.
 Corrected ISBN verification error. Re-compiled documentation in HTML form. Put
 in place proper error handling routines. --font option removed. Encoding is now
 done with a restructured zint_symbol structure. Added make install option and
 optional QR Code support to Makefile. Corrected minor problem with 4-State
 Codes. Restructured code into fewer source code files. Added MicroPDF417
 support. 12/8/2007
 v1.5.1 - Added formatting code to EPS output of EAN and UPC symbols according
 to EN 797:1996. Checked against and, where appropriate, altered or corrected to

 PDF417/MicroPDF417 byte processing. Transferred licence to GPL version 3.
 9/3/2008
 v1.6 - Data Matrix ECC200, Maxicode and Australia Post now use common
