-Version 1.6.17beta01 [January 29, 2015]
   Removed duplicate PNG_SAFE_LIMITS_SUPPORTED handling from pngconf.h
   Corrected the width limit calculation in png_check_IHDR().
   Removed user limits from pngfix. Also pass NULL pointers to

   Merged some parts of libpng-1.6.17beta01 and libpng-1.7.0beta47.
   Added #ifndef __COVERITY__ where needed in png.c, pngrutil.c and
     pngset.c to avoid warnings about dead code.
-  Added "& 0xff" to many instances of expressions that are typecast
-    to (png_byte), to avoid Coverity gripes.
-
-Version 1.6.17beta02 [February 7, 2015]
-  Work around one more Coverity-scan dead-code warning.
   Do not build png_product2() when it is unused.
-
-Version 1.6.17beta03 [February 17, 2015]
   Display user limits in the output from pngtest.
   Eliminated the PNG_SAFE_LIMITS macro and restored the 1-million-column
     and 1-million-row default limits in pnglibconf.dfa, that can be reset
     by the user at build time or run time.  This provides a more robust
     defense against DOS and as-yet undiscovered overflows.
-
-Version 1.6.17beta04 [February 21, 2015]
   Added PNG_WRITE_CUSTOMIZE_COMPRESSION_SUPPORTED macro, on by default.
   Allow user to call png_get_IHDR() with NULL arguments (Reuben Hawkins).
   Rebuilt configure scripts with automake-1.15 and libtool-2.4.6
-
-Version 1.6.17beta05 [February 25, 2015]
-  Restored compiling of png_reciprocal2 with PNG_NO_16BIT.
-
-Version 1.6.17beta06 [February 27, 2015]
   Moved png_set_filter() prototype into a PNG_WRITE_SUPPORTED block
     of png.h.
   Avoid runtime checks when converting integer to png_byte with
     Visual Studio (Sergey Kosarevsky)
-
-Version 1.6.17rc01 [March 4, 2015]
-  No changes.
-
-Version 1.6.17rc02 [March 9, 2015]
   Removed some comments that the configure script did not handle
     properly from scripts/pnglibconf.dfa and pnglibconf.h.prebuilt.
   Free the unknown_chunks structure even when it contains no data.
-
-Version 1.6.17rc03 [March 12, 2015]
   Updated CMakeLists.txt to add OSX framework, change YES/NO to ON/OFF
     for consistency, and remove some useless tests (Alexey Petruchik).
-
-Version 1.6.17rc04 [March 16, 2015]
-  Remove pnglibconf.h, pnglibconf.c, and pnglibconf.out instead of
-    pnglibconf.* in "make clean" (Cosmin).
-  Fix bug in calculation of maxbits, in png_write_sBIT, introduced
-    in libpng-1.6.17beta01 (John Bowler).
-
-Version 1.6.17rc05 [March 21, 2015]
-  Define PNG_FILTER_* and PNG_FILTER_VALUE_* in png.h even when WRITE
-    is not supported (John Bowler).  This fixes an error introduced in
-    libpng-1.6.17beta06.
-  Reverted "& 0xff" additions of version 1.6.17beta01. Libpng passes
-    the Coverity scan without them.
-
-Version 1.6.17rc06 [March 23, 2015]
-  Remove pnglibconf.dfn and pnglibconf.pre with "make clean".
-  Reformatted some "&0xff" instances to "& 0xff".
+  Remove pnglibconf.h, pnglibconf.c, pnglibconf.pre, pnglibconf.dfn,
+    and pnglibconf.out instead of pnglibconf.* in "make clean" (Cosmin).
   Fixed simplified 8-bit-linear to sRGB alpha. The calculated alpha
     value was wrong.  It's not clear if this affected the final stored
     value; in the obvious code path the upper and lower 8-bits of the
