  - Few small bug fixes in AlignmentPatternFinder, MultiFormatReader
    (thank K. Kakima, Andreas)
  - LCDUIImageMonochromeBitmapSource now public
  - Notably improved decoding for Basic version -- Regular version still
    your best bet if you can run it though

0.2.1 (16 Jan 2008)
  - Slight tweaks and enhancements to decode and runtime performance of UPCDecoder
  - Added black-box test suites against a known set of images
    (Thanks to Enrique G. S. for additional images)

0.2.2 (22 Jan 2008)
  - Now includes junit locally to build tests
  - Fixed "MIDlet" name in MANIFEST.MF, which may solve some problems
  - Friendlier error message when barcode can't be found

0.3 (04 Feb 2008)
  - Major refactoring of 1D barcode decoding
  - Added support for UPC-E, EAN-8
  - Also added Code 39, Code 128 support -- may need refinement
  - Now any "game" key triggers photo capture
  - Workaround implemented for Nokias that use "capture://image" in MMAPI
  - UPC codes now trigger lookup to upcdatabase.com

0.4 (15 Feb 2008)
  - First release of Android client -- only guaranteed to work with "M3"
    builds so far.
  - Major reorganization of current test cases and data
  - Worked around ProGuard issue with paths with spaces on Windows
  - Phones that don't like FocusControl.AUTO_LOCK won't cause an error now
  - Fixed ArrayIndexOutOfBoundsException in 1D barcode decoders
  - Worked around "java.lang.Error 136" from Nokia N70 (?)
  - Fixed bug in Shift_JIS detection and implemented basic UTF-8 detection
    for nonstandard QR Codes that don't use ISO-8859-1

0.4.5 (22 Feb 2008)
  - Checked in first minimal working Blackberry client. Still quite crude.
  - Fixed UTF-8 detection again
  - Refactored Reed-Solomon to allow different GF(256) primitive polynomials,
    in preparation for Data Matrix
  - Slight improvement to 1D decoding accuracy, most noticeable in
    improvements to Code 128 decoding
  - Bug fix in Code39Reader -- typo in encoding of letter "I" and "0"
  - Bug fix in 1D readers -- error in counting black/white pixel counts
    in certain situations
  - Now supports Extended Code 39
  - Tiny bug fix to QRCodeReader for images that extend all the way
    to top or left
  - Android client now builds with ProGuard optimization

0.5 (05 Mar 2008)
  - Improvement in QR Code decoding accuracy on non-JSR-234 phones
  - Supports "URLTO" data in barcodes.
  - Restructured ParsedReaderResult parsing code to not use so many
    exceptions, for more efficiency.
  - "TRY_HARDER" decoding hint now supported. Will do more work in some cases
    to find an image, such as scan for 1D barcodes at a right angle and
    backwards. Only recommended for non-mobile applications.
  - Result now indicates the format of the decoded barcode with a
    BarcodeFormat instance
  - More intelligent handling of POSSIBLE_FORMATS decoding hint
  - Fixed sub-optimal handling of EAN-13 barcodes which encode a string
    starting with "0". These are now returned as a full 13-digit string
    from EAN13Reader, but will continue to be construed as 12-digit UPC-A
    codes from the MultiFormatReader.
  - A host of small bug fixes, including bug in Version 25 QR Code support
  - A round of code cleanup and refactoring from IntelliJ inspections

0.5.5 (12 Mar 2008)
  - Revert change that rejected BufferedImage of type TYPE_CUSTOM in javase
  - Now supports KDDI/AU / Softbank address book format
  - Now can read Android "Intent" URIs (Android only)
  - Modest improvements to efficiency of J2ME client: shorter autofocus,
    better use of threads
  - First checkin of Data Matrix decoder code. Not yet enabled in reader
    applications.
  - "Result" object now returns raw bytes decoded; maybe useful in some cases
  - More unit tests for common code, EAN-8, UPC-E

0.6 (28 Mar 2008)
  - Updated android client to work on latest M5 SDK; M3-compatiable version
    preserved in android-m3
  - Added tel: URL support to clients
  - Added geo: URL support; only enabled for Android client so far
  - Added initial support for short NDEF messages, but not yet enabled
  - Bug fix to corner-case of perspective transformation code
  - Now attempts to configure camera's exposure controls if available
  - Fixed rotation transform used in "try harder" mode; result did not
    contain the whole image
  - "Try harder" mode tries 2D formats first to avoid false positives
    in detailed search for 1D codes, in some cases
  - More aggressive inlining by ProGuard, notable performance boost
  - Small Reed-Solomon optimizations for 0- and 1-error case
  - Refactored GridSampler out into common package for use by Data Matrix
  - GridSampler now smarter about bounds checking and point nudging;
    should avoid some ArrayIndexOutOfBoundsException issues
  - More unit tests

0.7 (5 May 2008)
  - Added support for MobileTag message formats
  - Added source to zxing.org
  - Significant work on Android clients, including UI overhaul and
    continuous scan mode
  - Bug fix: ResultPoints from 1D barcodes were wrong
  - SKIP_N_BARCODES hint now gone, and associated logic has been transferred
    to individual project users, as it is fairly app-specific at this point
    and is beginning to complicate the core library. We can help other users
    who need this functionality on a case-by-case basis.
  - Bug fix in AddressBookAUParsedResult parsing
  - Possible workaround for NoSuchMethodError on Nokias
  - New shell of an iPhone client committed
  - ... and other assorted small improvements and fixes
