Change log

6.1 (14 January 2019)

• Fix short chunks of data not being optimized to the correct mode.
• Tests fixed for Python 3

6.0 (23 March 2018)

• Fix optimize length being ignored in QRCode.add_data.
• Better calculation of the best mask pattern and related optimizations. Big thanks to cryptogun!

5.3 (18 May 2016)

• Fix incomplete block table for QR version 15. Thanks Rodrigo Queiro for the report and Jacob Welsh for the investigation and fix.
• Avoid unnecessary dependency for non MS platforms, thanks to Noah Vesely.
• Make BaseImage.get_image() actually work.

5.2 (25 Jan 2016)

• Add --error-correction option to qr script.
• Fix script piping to stdout in Python 3 and reading non-UTF-8 characters in Python 3.
• Fix script piping in Windows.
• Add some useful behind-the-curtain methods for tinkerers.
• Fix terminal output when using Python 2.6
• Fix terminal output to display correctly on MS command line.

5.2.1

• Small fix to terminal output in Python 3 (and fix tests)

5.2.2

• Revert some terminal changes from 5.2 that broke Python 3's real life tty code generation and introduce a better way from Jacob Welsh.

5.1 (22 Oct 2014)

• Make qr script work in Windows. Thanks Ionel Cristian Mărieș
• Fixed print_ascii function in Python 3.
• Out-of-bounds code version numbers are handled more consistently with a ValueError.
• Much better test coverage (now only officially supporting Python 2.6+)

5.0 (17 Jun 2014)

• Speed optimizations.
• Change the output when using the qr script to use ASCII rather than just colors, better using the terminal real estate.
• Fix a bug in passing bytecode data directly when in Python 3.
• Substation speed optimizations to best-fit algorithm (thanks Jacob Welsh!).
• Introduce a print_ascii method and use it as the default for the qr script rather than print_tty.

5.0.1

• Update version numbers correctly.

4.0 (4 Sep 2013)

• Made qrcode work on Python 2.4 - Thanks tcely. Note: officially, qrcode only supports 2.5+.
• Support pure-python PNG generation (via pymaging) for Python 2.6+ -- thanks Adam Wisniewski!
• SVG image generation now supports alternate sizing (the default box size of 10 == 1mm per rectangle).
• SVG path image generation allows cleaner SVG output by combining all QR rects into a single path. Thank you, Viktor Stískala.
• Added some extra simple SVG factories that fill the background white.

4.0.1

• Fix the pymaging backend not able to save the image to a buffer. Thanks ilj!

4.0.2

• Fix incorrect regex causing a comma to be considered part of the alphanumeric set.
• Switch to using setuptools for setup.py.

4.0.3

• Fix bad QR code generation due to the regex comma fix in version 4.0.2.

4.0.4

• Bad version number for previous hotfix release.

3.1 (12 Aug 2013)

• Important fixes for incorrect matches of the alpha-numeric encoding mode. Previously, the pattern would match if a single line was alpha-numeric only (even if others wern't). Also, the two characters { and } had snuck in as valid characters. Thanks to Eran Tromer for the report and fix.
• Optimized chunking -- if the parts of the data stream can be encoded more efficiently, the data will be split into chunks of the most efficient modes.

3.1.1

• Update change log to contain version 3.1 changes. :P
• Give the qr script an --optimize argument to control the chunk optimization setting.

3.0 (25 Jun 2013)

• Python 3 support.
• Add QRCode.get_matrix, an easy way to get the matrix array of a QR code including the border. Thanks Hugh Rawlinson.
• Add in a workaround so that Python 2.6 users can use SVG generation (they must install lxml).
• Some initial tests! And tox support (pip install tox) for testing across Python platforms.

2.7 (5 Mar 2013)

• Fix incorrect termination padding.

2.6 (2 Apr 2013)

• Fix the first four columns incorrectly shifted by one. Thanks to Josep Gómez-Suay for the report and fix.
• Fix strings within 4 bits of the QR version limit being incorrectly terminated. Thanks to zhjie231 for the report.

2.5 (12 Mar 2013)

• The PilImage wrapper is more transparent - you can use any methods or attributes available to the underlying PIL Image instance.
• Fixed the first column of the QR Code coming up empty! Thanks to BecoKo.

2.5.1

• Fix installation error on Windows.

2.4 (23 Apr 2012)

• Use a pluggable backend system for generating images, thanks to Branko Čibej! Comes with PIL and SVG backends built in.

2.4.1

• Fix a packaging issue

2.4.2

• Added a show method to the PIL image wrapper so the run_example function actually works.

2.3 (29 Jan 2012)

• When adding data, auto-select the more efficient encoding methods for numbers and alphanumeric data (KANJI still not supported).

2.3.1

• Encode unicode to utf-8 bytestrings when adding data to a QRCode.

2.2 (18 Jan 2012)

• Fixed tty output to work on both white and black backgrounds.
• Added border parameter to allow customizing of the number of boxes used to create the border of the QR code

2.1 (17 Jan 2012)

• Added a qr script which can be used to output a qr code to the tty using background colors, or to a file via a pipe.
