-  Refer to the libpng license instead of the libpng license in each file.
-
-version 1.4.0beta67 [July 6, 2009]

+  Align row_buf on 16-byte boundary in memory.
+  Restored the PNG_WRITE_FLUSH_AFTER_IEND_SUPPORTED guard around the call
+    to png_flush() after png_write_IEND().  See 1.4.0beta32, 1.4.0beta50
+    changes above and 1.2.30, 1.2.30rc01 and rc03 in 1.2.41 CHANGES.  Someone
+    needs this feature.

+    PNG_READ_COMPOSITE_NODIV_SUPPORTED is defined.
+  Changed "/255" to "/255.0" in background calculations to make it clear
+    that the 255 is used as a double.
+

+  Removed premultiplied alpha feature.
+
+version 1.4.0beta107 [December 4, 2009]
+  Updated README
+  Added "#define PNG_NO_PEDANTIC_WARNINGS" in the libpng source files.
+  Removed "-DPNG_CONFIGURE_LIBPNG" from the makefiles and projects.
+  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/libpng14 instead of in
+    $prefix/include/libpng/libpng14.
+
+version 1.4.0beta108 [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 1.4.0beta109 [December 13, 2009]
+  Added "bit_depth" parameter to the private png_build_gamma_table() function.
+  Pass bit_depth=8 to png_build_gamma_table() when bit_depth is 16 but the
+    PNG_16_TO_8 transform has been set, to avoid unnecessary build of 16-bit
+    tables.
+
+version 1.4.0rc02 [December 20, 2009]
+  Declared png_cleanup_needed "volatile" in pngread.c and pngwrite.c
+
+version 1.4.0rc03 [December 22, 2009]
+  Renamed libpng-pc.in back to libpng.pc.in and revised CMakeLists.txt
+    (revising the change in 1.4.0beta99)
+
+version 1.4.0rc04 [December 25, 2009]
+  Swapped PNG_UNKNOWN_CHUNKS_SUPPORTED and PNG_HANDLE_AS_UNKNOWN_SUPPORTED
+    in pngset.c to be consistent with other changes in version 1.2.38.
+
+version 1.4.0rc05 [December 25, 2009]
+  Changed "libpng-pc.in" to "libpng.pc.in" in configure.ac, configure, and
+    Makefile.in to be consistent with changes in libpng-1.4.0rc03
+
+version 1.4.0rc06 [December 29, 2009]

+version 1.4.1beta01 [January 8, 2010]
+  Updated CMakeLists.txt for consistent indentation and to avoid an
+    unclosed if-statement warning (Philip Lowman).
+  Revised Makefile.am and Makefile.in to remove references to Y2KINFO,
+    KNOWNBUG, and libpng.la (Robert Schwebel).

+    links as configure, except for libpng.la and libpng14.la.

+    PNG_WRITE_SUPPORTED is not enabled.
+  Revised Makefile.am and Makefile.in to simplify their maintenance.
+  Revised scripts/makefile.linux to install a link to libpng14.so.14.1

 We removed the trailing '.' from the warning and error messages.

-We added PNG_TRANSFORM_GRAY_TO_RGB to the available high-level
-input transforms.
-
-The png_struct and info_struct members "trans" and "trans_values" were
-changed to "trans_alpha" and "trans_color", respectively.
-
-The call to png_do_chop() in pngrtran.c, which reduces 16-bit input
-files to 8-bit bit depth, was relocated ahead of the building
-of gamma tables.  This allows us to build 8-bit tables instead
-of 16-bit tables, when only 8-bit tables are needed. This avoids 
-wasting some computing resources when the application has called
-the png_set_strip_16() function and encounters a 16-bit PNG file.
-
-Checking for and reporting of errors in the IHDR chunk is more thorough.

+The xcode project has not been entirely updated to libpng-1.4.0.
+
+It needs to *not* depend on pnggccrd.c or pngvcrd.c
+
+It needs to PNG_NO_PEDANTIC_WARNINGS in the CFLAGS while building
+the library, but not while building an application.
+
+If an updated version is not received, this project will
+be removed when libpng-1.4.0 is released.
