+
+  Revised libpng*.txt and libpng.3 to mention calling png_set_IHDR()
+    multiple times and to specify the sample order in the tRNS chunk,
+    because the ISO PNG specification has a typo in the tRNS table.
+  Changed several PNG_UNKNOWN_CHUNK_SUPPORTED to
+    PNG_HANDLE_AS_UNKNOWN_SUPPORTED, to make the png_set_keep mechanism
+    available for ignoring known chunks even when not saving unknown chunks.
+  Added PNG_NO_HANDLE_AS_UNKNOWN in the PNG_LEGACY_SUPPORTED block of
+    pngconf.h, and moved the various unknown chunk macro definitions
+    outside of the PNG_READ|WRITE_ANCILLARY_CHUNK_SUPPORTED blocks.
+  Added a reference to the libpng license in each source file.
+  Rebuilt configure scripts with autoconf-2.63.
 
-version 1.0.46 [June 18, 2009]
 
-  Fixed a mistake in the editing script that changes the scripts files
-    to version 1.0.x, which created an erroneous libpng.pc and some makefiles.
-    The error was introduced in libpng-1.0.45.
