 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.

   Changed png_struct jmp_buf member name from png_jmpbuf to tmp_jmpbuf to
     avoid a clash with the png_jmpbuf macro on some platforms.
 
-Version 1.5.3beta05 [May 4, 2011]
+Version 1.5.3beta05 [May 5, 2011]
   Added appropriate feature test macros to ensure libpng sees the correct API
    _POSIX_SOURCE is defined in pngpriv.h, pngtest.c and pngvalid.c to ensure
     that POSIX conformant systems disable non-POSIX APIs.  _ISOC99_SOURCE is
     defined in pngpriv.h to obtain the ISO C99 snprintf definition, when
     available.
+  Removed png_snprintf and added formatted warning messages.  This change adds
+    internal APIs to allow png_warning messages to have parameters without
+    requiring the host OS to implement snprintf.  As a side effect the
+    dependency of the tIME-supporting RFC1132 code on stdio is removed and
+    PNG_NO_WARNINGS does actually work now.
