- 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)

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

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.

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.

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

- 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

and is beginning to complicate the core library. We can help other users
who need this functionality on a case-by-case basis.
