-Libpng 1.2.1rc2 - December 4, 2001
+Libpng 1.2.1 - December 12, 2001
 
-This is not intended to be a public release.  It will be replaced
-within a few weeks by a public version or by another test version.
+This is a public release of libpng, intended for use in production codes.
 
 Changes since the last public release (1.2.0):
 
-version 1.2.1beta1 [October 19, 2001]
   Revised makefile.std in contrib/pngminus
   Include background_1 in png_struct regardless of gamma support.
   Revised makefile.netbsd and makefile.macosx, added makefile.darwin.
   Revised example.c to provide more details about using row_callback().
-version 1.2.1beta2 [October 25, 2001]
-  Added type cast to each NULL appearing in a function call, except for
-    WINCE functions.
   Added makefile.so9.
-version 1.2.1beta3 [October 27, 2001]
-  Removed type casts from all NULLs.
-  Simplified png_create_struct_2().
-version 1.2.1beta4 [November 7, 2001]
-  Revised png_create_info_struct() and png_creat_struct_2().
+  Removed type casts from all NULLs, except for those appearing in function
+    calls when PNG_NO_TYPECAST_NULL is defined.
+  Simplified png_create_info_struct() and png_creat_struct_2().
   Added error message if png_write_info() was omitted.
-  Type cast NULLs appearing in function calls when _NO_PROTO or
-    PNG_TYPECAST_NULL is defined.
-version 1.2.1rc1 [November 24, 2001]
-  Type cast NULLs appearing in function calls except when PNG_NO_TYPECAST_NULL
   Changed typecast of "size" argument to png_size_t in pngmem.c calls to
     the user malloc_fn, to agree with the prototype in png.h
   Added a pop/push operation to pnggccrd.c, to preserve Eflag (Maxim Sobolev)
   Updated makefile.sgi to recognize LIBPATH and INCPATH.
   Updated various makefiles so "make clean" does not remove previous major
     version of the shared library.
-version 1.2.1rc2 [December 4, 2001]
   Added a pop/push operation to pngvcrd.c, to preserve Eflag.
   Always allocate 256-entry internal palette, hist, and trans arrays, to
     avoid out-of-bounds memory reference caused by invalid PNG datastreams.
