|
|
|
|
|
|
Version 4.0.2 (2018.6.6)
|
|
------------------------
|
|
* Build script fixes. (Thanks to @mgorny)

|
|
|
|
Release Note:
|
|
While the API has not been changed since the previous major release, we
|
|
incremented the major version number of libqrencode to 4 because the
|
|
implementation of the library has been largely changed.
|
|
|
|
This release improves the performance and memory footprints of code generation.
|
|
|
|
Now you can build libqrencode with CMake.
|
|
|
|
If you build the test programs, please note that the required SDL version has
|
|
been changed from 1.2 to 2.0.
|
|
|
|
|
|
Version 3.4.4 (2014.7.24)
|
|
-------------------------
|
|
* Bug fix release. (Thanks to Yoshimichi Inoue)
|
|
* New option "--verbose" has been added to the command line tool.
|
|
|
|
Release Note:
|
|
When only one symbol is generated in structured-append mode, the library had
|
|
inserted unnecessary chunk to the symbol and some QR Code readers fail to read
|
|
it. Now the library omits the chunk and generate a symbol identical to non-
|
|
structured symbol.
|
|
|
|
Version 3.4.3 (2013.8.12)
|
|
-------------------------
|
|
* New option "--rle" has been added to the command line tool (Thanks to Daniel
|
|
Dörrhöfer)
|
|
* Bug fixes. (Thanks to Hassan Hajji, Emmanuel Blot, and ßlúèÇhîp)
|
|
|
|
Release Note:
|
|
This release contains a couple of bug fixes and a new minor feature of the
|
|
command line tool. Some minor bugs in the library have been fixed.
|
|
|
|
Run Length Encoding (RLE) for SVG output decreases the size of the output file,
|
|
but it makes complicated to edit the image by SVG editors. A newly introduced
|
|
command line option "--rle" enables RLE. RLE will not be applied if it is not
|
|
given.
|
|
|
|
Version 3.4.2 (2013.3.1)
|
|
------------------------
|
|
* Bug fix release. (Thanks to chisj, vlad417, Petr and Viona)
|
|
|
|
Release Note:
|
|
Micro QR Code encoder had a bug that caused incorrect output (issue #25). Now
|
|
the bug has been fixed. Memory leak bug (#24) and insufficient string splitting
|
|
bug have been fixed.
|
|
|
|
Version 3.4.1 (2012.10.17)
|
|
--------------------------
|
|
* Bug fix release.
|
|
|
|
Release Note:
|
|
Mutual exclusion did not work correctly since 3.3.1. If your application uses
|
|
libqrencode in multithreaded environment, it is strongly recommended to update
|
|
it.
|
|
|
|
Version 3.4.0 (2012.10.15)
|
|
--------------------------
|
|
* SVG, UTF8, and ANSIUTF8 output supports have been added to the command line
|
|
tool. (Thanks to Dan Storm, David Dahl, and Lennart Poettering)
|
|
* Colored QR Code support.
|
|
* Bug fixes. (Thanks to Terry Burton, Fred Steinhaeuser, and Yann Droneaud)
|
|
|
|
Release Note:
|
|
Three new output format, SVG, UTF8, and ANSIUTF8 have been added to the command
|
|
line tool. UTF8 and ANSIUTF8 are another text art mode, using Unicode block
|
|
elements for high-resolution text output. Long-awaited colored QR code has been
|
|
introduced. Try "--foreground" and "--background" options to set the colors.
|
|
Currently PNG and SVG supports colored output.
|
|
|
|
Version 3.3.1 (2012.4.18)
|
|
-------------------------
|
|
* Bugs in command line tool, manual, configure script, and libtool files have
|
|
been fixed. (Thanks to Yutaka Niibe and Rob Ryan)
|
|
|
|
Version 3.3.0 (2012.4.1)
|
|
-------------------------
|
|
* EPS, ANSI, and ASCII text output supports have been added.
|
|
(Thanks to Zapster, Colin, and Ralf)
|
|
* QRcode_APIVersion() and QRcode_APIVersionString() have been added.
|
|
|
|
Release Note:
|
|
Three new output format, EPS, ANSI, and ASCII text, have been added to the
|
|
command line tool. ANSI and ASCII mode ignore "-size" option. Give "-t ASCIIi"
|
|
to get an ASCII-mode symbol in inverted color.
|
|
|
|
QRcode_APIVersion() is requested by Matthew Baker for better support of Python
|
|
ctypes binding. Check them out at https://code.google.com/p/libqrencode-ctypes/
|
|
|
|
Version 3.2.1 (2012.4.1)
|
|
------------------------
|
|
* Bugs in configure script and libtool file has been fixed. (Thanks to Yutaka
|
|
Niibe)
|
|
|
|
Version 3.2.0 (2011.11.26)
|
|
--------------------------
|
|
* "--dpi" (or "-d") option has been added to qrencode. This option set DPI
|
|
information in an output PNG image. (Thanks to David Dahl)
|
|
* New option "--enable-thread-safety" has been added to the configure script
|
|
that makes the library thread-safe. It is enabled by default.
|
|
* QRcode_encodeData(), QRcode_encodeDataMQR, QRcode_encodeDataStructured() have
|
|
been added for binary data encoding including '\0'.
|
|
* Typo and bug fixes.
|
|
* Experimental Micro QR Code support has been added.
|
|
* "--micro" (or "-M") option for Micro QR Code has been added to qrencode.
|
|
(experimental)
|
|
|
|
Release Note:
|
|
Binary data including '\0' is now supported. To encode a binary data, give "-8"
|
|
option to qrencode, and let qrencode obtain data via standard input like
|
|
"qrencode -8 -o output.png < binary". "--dpi" and "-d" are also added to embed
|
|
DPI information to PNG file.
|
|
|
|
A bug in the mask pattern evaluation routine has been fixed. In some cases,
|
|
libqrencode may generate a different symbol from the one that was generated by
|
|
the prior libqrencode because of this bug fix, but the embedded data are not
|
|
affected. The symbols generated by the old libqrencode are valid.
|
|
|
|
Experimental support of Micro QR Code encoder has been added. Some functions
|
|
(QRcode_*MQR()) have been added to the library. The command line tool generates
|
|
Micro QR Code when "--micro" or "-M" is given.
|
|
|
|
Version 3.1.1 (2010.2.3)
|
|
------------------------
|
|
* A bug in the library has been fixed.
|
|
|
|
Release Note:
|
|
Libqrecode had generated incorrect QR Code in some cases. Symbols larger than
|
|
version 5 (error correction level Q and H) were affected. In many cases this
|
|
bug did not cause serious damage thanks to the error correction mechanism, but
|
|
we highly recommend you to encode symbols again using this release.
|
|
|
|
Version 3.1.0 (2009.6.6)
|
|
------------------------
|
|
* Various code cleanups and performance improves.
|
|
* Strict internal error checks have been added.
|
|
* "--without-tests" has become default setting. Specify "--with-tests" to
|
|
compile test programs.
|
|
* Some memory leak bugs have been fixed.
|
|
|
|
Release Note:
|
|
This release focuses on the code cleanup and performance improve. Encoding time
|
|
has been improved, drastically in large symbols. Basically this update only
|
|
changes its internal code. The API is not changed, no need to recompile user
|
|
applications that includes only qrencode.h. If your application refers the
|
|
internal data representation (not recommended), see ChangeLog for further
|
|
information.
|
|
|
|
Version 3.0.3 (2008.6.1)
|
|
------------------------
|
|
* Portability enhancement. (Thanks to Gavan Fantom)
|
|
* The command line tool "qrencode" now accepts long options. See the man page
|
|
for the detailed instruction.
|
|
|
|
Release Note:
|
|
This release improves the portability of our command line tool "qrencode".
|
|
The library is not changed so that any applications using libqrencode are not
|
|
affected.
|
|
|
|
From this release, qrencode accepts "long" options, such as "--help". See the
|
|
manpage for the detailed instructions.
|
|
|
|
Qrencode now uses getopt_long() instead of getopt_long_only() which is not
|
|
available in some operating systems. If the getopt_long() is not provided or
|
|
the implementation of it is not compatible with GNU's one, please try
|
|
qrencode-3.0.3-gnulib, that contains the source code of the getopt_long().
|
|
Gnulib version is a test release. If you feel happy with it, please let us know
|
|
and the future releases will include gnulib.
|
|
|
|
Version 3.0.2 (2008.5.18)
|
|
-------------------------
|
|
* Some compile-time warnings/errors with g++ have been fixed.
|
|
(Thanks to wangsai)
|
|
* The bit order of "Version information" has been corrected.
|
|
Symbols greater than version 6 were affected. (Thanks to Paul Janssesn)
|
|
* The "--without-tests" option has been added to the configure script.
|
|
|
|
Version 3.0.1 (2008.5.9)
|
|
------------------------
|
|
* A bug fix for non-POSIX platform. (Thanks to Paul Janssens)
|
|
* The RPM spec file now packages the man page correctly.
|
|
|
|
Version 3.0.0 (2008.4.30)
|
|
-------------------------
|
|
* The interface of QRencode_encodeInput() has been changed. User applications
|
|
using it must be modified.
|
|
* Structured append support has been added. (patches from Yusuke Mihara)
|
|
* The "-S" option for structured append has been added to qrencode and
|
|
view_qrcode.
|
|
* Some functions now set errno to indicate errors.
|
|
* Some bug fixes.
|
|
|
|
Release Note:
|
|
Now libqrencode supports "structured-append" of symbols. A large data set can
|
|
be split into multiple QR code symbols. The basic usage of structured-append
|
|
is not so different from the single symbol encoding: just call
|
|
QRcode_encodeStringStructured() or QRcode_encodeString8bitStructured() and
|
|
they return a list of symbols. Instead of giving a string, you can encode
|
|
an explicitly typed data. See the manual generated by Doxygen for the detailed
|
|
usage.
|
|
|
|
Many thanks to Yusuke Mihara, who contributed a patch to add support of
|
|
structured-append to version 1.0.2.
|
|
|

Version 2.0.0 (2008.1.24)
|
|
-------------------------
|
|
* "-i" option to ignore case distinctions has been added to qrencode and
|
|
view_qrcode.
|
|
* "-c" option (case-sensitive mode) of qrencode is now enabled by default and
|
|
has been improved. See details in Release Note section.
|
|
* "-8" option has been added to qrencode to encode whole data in 8-bit mode.
|
|
* tests/view_qrcode now accepts various options like qrencode.
|
|

|
|
* Code cleanup.
|
|
* The mask evaluation bug has been fixed. (Philippe Delcroix)
|
|
|
|
* API changes
|
|
- QRcode_encodeString() now receives case-sensitive flag.
|
|
- QRcode_encodeStringCase() has been removed.
|
|
- QRcode_encodeString8bit() has been added.
|
|
|
|
Release Note:
|
|
Previously libqrencode encodes lower-case alphabet characters in Alphabet-
|
|
Numeric mode (upper-case alphabet and numeric) by default. According to the
|
|
specification of QR code, however, it is clearly claimed that Alphabet-Numeric
|
|
mode provides only upper-case alphabet (+ numeric and some symbol) characters.
|
|
Since this version, libqrencode distinguishes lower-case and upper-case of
|
|
alphabet characters by default. Because of that, "-c" option of qrencode
|
|
is now deprecated, and "-i" option has been added. By giving "-i", qrencode
|
|
converts lower-case characters to upper-case if possible, then encode a QR code
|
|
symbol. Please read qrencode.h for the details about API changes if you are
|
|
going to use this library.
|
|
|
|
Many thanks to NANKI Haruo for his suggestions.
|
|
