+Changes since the last public release (1.0.52):

-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/libpng%NN% instead of in
-    $prefix/include/libpng/libpng%NN%.
-  Removed leftover "-DPNG_CONFIGURE_LIBPNG" from scripts/makefile.darwin
+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

-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 1.2.43beta02 [February 1, 2010]
+  Backported two-pass png_decompress_chunk() algorithm from libpng-1.4.1

-version 1.2.42rc01 [December 17, 2009]
+version 1.2.43beta03 [February 6, 2010]
+  Backported fast png_push_save_buffer() algorithm from libpng-1.4.1
+
+version 1.2.43beta04 [February 8, 2010]
+  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]
  No changes.

-version 1.2.42rc02 [December 23, 2009]

   Y2K compliance in libpng:
   =========================

-      December 23, 2009
+      February 18, 2010

      Since the PNG Development group is an ad-hoc body, we can't make
      an official declaration.

      This is your unofficial assurance that libpng from version 0.71 and
-      upward through 1.2.42rc02 are Y2K compliant.  It is my belief that earlier
+      upward through 1.0.53rc01 are Y2K compliant.  It is my belief that earlier
      versions were also Y2K compliant.

      Libpng only has three year fields.  One is a 2-byte unsigned integer

-Support for the iTXt chunk has been enabled by default as of

-
-Support for certain MNG features was enabled.

-Support for numbered error messages was added.  However, we never got

-png_set_strip_error_numbers() was added (Note: the prototype for this
-function was inadvertently removed from png.h in PNG_NO_ASSEMBLER_CODE

-
-The png_malloc_warn() function was added at libpng-1.2.3.  This issues

-acquire the requested memory allocation.
-
-Support for setting user limits on image width and height was enabled
