+Changes since the last public release (1.2.7):
 
-  Revised pngtest so memory allocation testing is only done when PNG_DEBUG==1.
-  Removed unused pngasmrd.h file.
-  Removed references to uu.net for archived files.  Added references to
-    PNG Spec (second edition) and the PNG ISO/IEC Standard.
-  Added "test-dd" target in 15 makefiles, to run pngtest in DESTDIR.
-  Fixed bug with "optimized window size" in the IDAT datastream, that
-    causes libpng to write PNG files with incorrect zlib header bytes.
-  Fixed bug with sCAL chunk and big-endian machines (David Munro).
-  Undid new code added in 1.2.6 to update the color_type in
-    png_set_filler().
-  Added png_set_add_alpha() that updates color type.
-  Revised png_set_strip_filler() to not remove alpha if color_type has alpha.
-  Added makefile.hp64
-  Changed projects/msvc/png32ms.def to scripts/png32ms.def in makefile.cygwin
+  Fixed bug in png_text_compress() that would fail to complete a large block.

+  Fixed bug, introduced in libpng-1.2.7, that overruns a buffer during

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

+      November 1, 2004
 
       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 1.2.7 are Y2K compliant.  It is my belief that earlier
+      upward through 1.2.8beta1 are Y2K compliant.  It is my belief that earlier
       versions were also Y2K compliant.
