+version 1.2.34beta01 [December 18, 2008]
+ Revised png_warning() to write its message on standard output by default
+ when warning_fn is NULL. This was the behavior prior to libpng-1.2.9.
+ Fixed string vs pointer-to-string error in png_check_keyword().
+ Added png_check_cHRM_fixed() in png.c and moved checking from pngget.c,
+ pngrutil.c, and pngwrite.c, and eliminated floating point cHRM checking.
+ Added check for zero-area RGB cHRM triange in png_check_cHRM_fixed().
+ In png_check_cHRM_fixed(), ensure white_y is > 0, and removed redundant
+ check for all-zero coordinates that is detected by the triangle check.
+ Revised png_warning() to write its message on standard output by default
+ when warning_fn is NULL.
+ Corrected off-by-one error in bKGD validity check in png_write_bKGD()
+ and in png_handle_bKGD().
+ Merged with png_debug from libpng-1.4.0 to remove newlines.
+ Removed redundant check for key==NULL before calling png_check_keyword()
+ to ensure that new_key gets initialized and removed extra warning
+ (Arvan Pritchard).
+ Added PNG_TRANSFORM_STRIP_FILLER_BEFORE and
+ PNG_TRANSFORM_STRIP_FILLER_AFTER conditionals and deprecated
+ PNG_TRANSFORM_STRIP_FILLER (Jim Barry).
