-Version 1.5.30beta01 [August 28, 2017]

     parenthesis in contrib/pngminus/pnm2png.c (bug report by Christian Hesse).
   Fixed off-by-one error in png_do_check_palette_indexes() (Bug report
     by Mick P., Source Forge Issue #269).
-
-Version 1.5.30beta02 [September 14, 2017]
   Compute a larger limit on IDAT because some applications write a deflate
     buffer for each row (Bug report by Andrew Church).
   Fixed incorrect typecast of some arguments to png_malloc() and
     png_calloc() that were png_uint_32 instead of png_alloc_size_t
     (Bug report by "irwir" in Github libpng issue #175).
-
-Version 1.5.30beta03 [September 20, 2017]
   Initialize memory allocated by png_inflate to zero, using memset, to
     stop an oss-fuzz "use of uninitialized value" detection in png_set_text_2()
-    due to truncated iTXT or zTXT chunk.
