+
+version 0.2:
+ * update distribution to include debian packaging
+ * add consistency checking to zebracam
+ * add redundant output suppression to zebraimg
+ * fix couple of Code 128 decode table bugs
+ * fix reversed Code 128 decode
+ * add outstanding scanner edge flush to new_scan()
+ - API change: scanner reset/new_scan() now return scan/decode status
+ - update zebracam and zebraimg to call this between each walker pass
+ (interface still needs improvement...)
+ => improves in scan results for many cases
+ * fix dbg_scan filename generation so results go in local directory
+ * continue Code 128 refinement
+ - finish character set C decode/expansion
+ - add per-character validation
+ - resolve scan direction in separate postprocessing pass before handling
+ ASCII conversion
+ - add several img_walker passes parallel to major axis (for long symbols)
+ - add simple character set C example to test_decode
+ * promote zebraimg images to TrueColor so colored scan pattern always shows
+ * more dbg_scan tweaks
+ * significant scanner improvements
+ - changed "classic" [-1 0 1] first differential kernel to [-1 1]
+ to improve minimum edge resolution to single pixel elements
+ => still need to do some more research and validate assumptions
+ - adaptive thresholding fixes
+ - adjusted filtering for better edge detection
+ - separate constants out to defines (FIXME add config API?)
+ * fix EAN-13 secondary determinant decoding
+ * dbg_scan tweaks to make annotations smaller/more usable
+ * add get_color() interface to decoder
+ * annotated zebraimg scan pattern for marginally useful high-level debug
+ * random include cleanup

+ - separate out more EAN state from shared state
+ - internal interface changes
+ - finish dynamic buffer management
+ - add shared resource locking
+ - add Code 128 to test_decode program
+ => still needs additional functionality and plenty of debug
+ => reading both Code 128 *and* EAN still destabilized
+ * add diagnostic program test_video to dump more verbose video debug
+ * incorporate documentation into Debian package
+ - thanks to V�t Hrachov� for the patch!
+ * fix VPATH doc builds (requires automake-1.10 and autoconf-2.61)

+ - suppress documentation rebuilds in distributed sources
+ * add Debian packaging sources - thanks to V�t Hrachov� for the patch!
+ * add DocBook template and build infrastructure
+ * add manpages for zebracam and zebraimg
+ * add GNU standard options to zebracam and zebraimg
+ * internal decoder restructuring to support additional symbologies
+ - separated out 1-D decoder infrastructure into generic internal API
+ - moved EAN/UPC specific decoding into it's own module
+ * fix confusing configure behavior which quietly avoided building
+ targets with missing dependencies(?!)
+ configure will now fail with a descriptive error message if you
+ do not have Magick++ and fail to specify --without-imagemagick or
+ do not have SDL and fail to specify --without-sdl
+ * add configure summary describing what will be built (req #1698196)
+ * fix parity encoding in test_decode and add decoded symbol output
