version 1.2.42beta01 [December 4, 2009]
Removed "#define PNG_NO_ERROR_NUMBERS" that was inadvertently added
to pngconf.h in version 1.2.41.
Revised scripts/makefile.netbsd, makefile.openbsd, and makefile.sco
to put png.h and pngconf.h in $prefix/include, like the other scripts,
instead of in $prefix/include/libpng. Also revised makefile.sco
to put them in $prefix/include/libpng12 instead of in
$prefix/include/libpng/libpng12.
Removed leftover "-DPNG_CONFIGURE_LIBPNG" from scripts/makefile.darwin
version 1.2.42beta02 [December 11, 2009]
Removed leftover "-DPNG_CONFIGURE_LIBPNG" from contrib/pngminim/*/makefile
Relocated png_do_chop() to its original position in pngrtran.c. The
change in version 1.2.41beta08 caused transparency to be handled wrong
in some 16-bit datastreams (Yusaku Sugai).
version 1.2.42rc01 [December 17, 2009]
No changes.
version 1.2.42rc02 [December 22, 2009]

(revising changes made in 1.2.41beta17 and 1.2.41rc01)
version 1.2.42rc03 [December 25, 2009]

Marked png_memcpy_check() and png_memset_check() PNG_DEPRECATED.
Updated copyright year.

Avoid deprecated references to png_ptr-io_ptr and png_ptr->error_ptr
in pngtest.c

No changes.
version 1.2.43beta01 [January 27, 2010]
Updated CMakeLists.txt for consistent indentation and to avoid an
unclosed if-statement warning (Philip Lowman).
Removed "#ifdef PNG_1_0_X / #endif" surrounding
PNG_READ_16_TO_8_SUPPORTED and PNG_READ_GRAY_TO_RGB_SUPPORTED
in pngconf.h. These were added in libpng-1.2.41beta08 and libpng-1.0.51,
which introduced a binary incompatibility with libpng-1.0.50.
Backported new png_decompress_chunk() algorithm from libpng-1.4.1.

Backported two-pass png_decompress_chunk() algorithm from libpng-1.4.1.

Reverted recent changes to png_push_save-buffer().
Removed PNGAPI declaration of png_calloc() and png_write_sig() in
1ibpng-1.2.X, introduced by mistake in libpng-1.2.41.
Return allocated "old_buffer" in png_push_save_buffer() before png_error()
to avoid a potential memory leak.
version 1.2.43beta05 [February 8, 2010]
Ported rewritten png_decompress_chunk() by John Bowler from libpng-1.4.1.
version 1.0.53rc01 and 1.2.43rc01 [February 18, 2010]
