[png-mng-announce] libpng-1.5.8 is available

libpng-1.5.8 has been released and is available from
ftp://ftp.simplesystems.org/pub/png/src
and from
http://libpng.sf net

Changes since the last public release (1.5.7):
  Removed '#include config.h"' from contrib/libtests/pngvalid.c.  It's not
    needed and causes trouble for VPATH building.
  Moved AC_MSG_CHECKING([if libraries can be versioned]) later to the proper
    location in configure.ac (Gilles Espinasse).
  Fix bug in pngerror.c: some long warnings were being improperly truncated
    (bug introduced in libpng-1.5.4).
  Fixed Min/GW uninstall to remove libpng.dll.a
  Conditionalize the install rules for MINGW and CYGWIN in CMakeLists.txt

The pngerror.c bug is a possible 1-bit overflow of long warning and
error messages, and is the subject of CVE-2011-3464 (which I have not
seen yet).
