All of the code in Zint is developed using information in the public domain, usually freely available on the Internet. Some of the techniques used may be subject to patents and other intellectual property legislation. It is my belief that any patents involved in the technology underlying symbologies utilised by Zint are 'unadopted', that is the holder does not object to their methods being used. If, however, you are a patent holder or hold any other intellectual property rights on the methods used by Zint or the symbologies which Zint generates, and do not want Zint to continue to support your symbology then please contact me and I will update the code to accommodate your wishes at the soonest opportunity.

v0.1 - (as Zebar) Draws UPC-A. UPC-E, EAN-8, EAN-13, Interlaced 2 of 5, Codabar, Code 39, Extended Code 39 and Code 93 barcodes and Add-on codes EAN-2 and EAN-5 without parity. 13/11/2006
v0.2 - Added Code 128 (which is now the default), Code 11, Code 2 of 5, Add-on codes EAN-2 and EAN-5 parity and MSI/Plessey without check digit. 12/12/2006
v0.3 - Added MSI/Plessey Mod 10 check and 2 x Mod 10 check options, Telepen ASCII and Telepen numeric, Postnet, RM4SCC. Code has been tidied up quite a bit. Bind option added. 30/12/2006
v0.4 - Added barcode stacking (now stacks up to 16 barcodes) and Code16k (stub). 15/1/2007
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). Errors now output to stderr. Added proper input verification. Distribution now packs with this HTML page instead of separate README. Outputs to PNG. Outputs 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
v1.0 - Corrected problem with escape character codes. Supports PDF417. This completes the list of features I originally wanted (plus a few more), hence skip to version 1.0. 20/4/2007
v1.1 - Added more derivatives (Code 2 of 5 Matrix, IATA and Data Logic, Truncated PDF417, Deutsche Post Leitcode and Identcode, Pharmazentralnummer, Planet) and Flattermarken. Tidied up 2 of 5 code. 26/4/2007
v1.2 - Supports Data Matrix (by absorption of IEC16022 code by Stefan Schmidt et al). Added reverse colours, FIM, MSI/Plessey Modulo 11 and Modulo 11/10. Corrected Code 16k check digit calculation. 28/5/2007
v1.3 - Supports USPS OneCode and LOGMARS. Brought all usage information into one User Manual document. 13/6/2007
v1.4 - Added NVE-18 support. Corrected some problems with compilation and input verification. Added zint.1 man page. 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 comply with ISO 16388 and ISO 15417 including Latin-1 support. Altered default image settings, added automatic ITF border. Corrected error with USPS OneCode. Tidied up Code 39 quite a bit, added Mod 43 options. 3/9/2007
v1.5.2 - Added extended ASCII support to Code 16k. Corrected Code 128 error. Added Maxicode support by integrating code by John Lien. 26/9/2007
v1.5.3 - Made huge corrections to Maxicode support by removing and re-writing much of John's code. Maxicode now supports extended ASCII and modes 4, 5 and 6. 10/10/2007
v1.5.4 - Added GS1 DataBar (Reduced Space Symbology) support. 26/11/2007
v1.5.5 - Added composite symbology support. Corrected errors with GS1-128 and PDF417/MicroPDF417 byte processing. Transferred licence to GPL version 3. 9/3/2008
v1.6 – Data Matrix, Maxicode and Australia Post now use common Reed-Solomon functions – this also fixes a bug in Maxicode error correction and replaces the last of the Lien code. Added PNG output for Maxicode symbols. Removed some useless code. Updated QR support for libqrencode v2.0.0. 22/4/2008
v1.6.1 – Major restructuring of PNG generating code: Now draws UPCA and EAN symbols properly and puts human readable text into the image. Also corrected some nasty 'never ending loop' bugs in Code 128 and check digit bugs in PostNet and Planet. 8/7/2008
v1.6.2 – Added KIX Code support and PNG image rotation. Corrected a bug affecting extended ASCII support in Code 128 and Code 16k. 28/7/2008.
v1.6.3 – Added Aztec Code and Code 32 support.
