Log message:
Reset maintainer for resigned developers.

Log message:
Changes 1.7.69:
* Check for NULL return from malloc().
* Undefine CLOCKS_PER_SECOND "1000" found in some version of MinGW.
* Replaced most "atoi(argv[++i])" with "pngcrush_get_long" \ 
which does
    "BUMP_I; strtol(argv[i],ptr,10)" and added pngcrush_check_long macro
    to detect malformed or missing parameters (debian bug 716149).
* Added global_things_have_changed=1 when reading -bkgd.
* The "-bit_depth N" option did not work reliably and has been removed.

Log message:
Changes 1.7.67:
Fixed handling of "-text" and "-ztext" options for text \ 
input. They had been
reduced to "-t" and "-z" with an incorrect argument (3 \ 
instead of 2) in
version 1.7.62.

Log message:
Changes 1.7.66:
Revised pngcrush_examine_pixels_fn() to fix some incorrect reductions.

Log message:
Changes 1.7.63:
Add "int dowildcard=-1;" in an attempt to get wildcard arguments working
in the cross-compiled MinGW executables.

Log message:
Changes 1.7.58:
* Do not enable reduce_palette by default for "-reduce", \ 
"-new", or "-old".
    It still is failing for some files.

Log message:
Changes 1.7.56:
  Only use pngcrush_debug_malloc() and pngcrush_debug_free() if the result
    is going to be shown.
  Added PNG_PASS_ROWS, PNG_UNUSED, and other macro definitions, when building
    with libpng-1.4.x and older libpng versions.
  Multiplied rowbytes by 8/bit_depth when using the system library because
    we do not call png_read_transform_info(). This prevents a crash when
    reading sub-8-bit input files.

Log message:
Version 1.7.53:
* Removed plte_len stuff from the "To do" list because it is done.
* Shorten the indexed-PNG tRNS chunk length if it has more entries than the PLTE \ 
chunk.

Log message:
Version 1.7.52 (built with libpng-1.6.1beta06 and zlib-1.2.7)
  Added license info for cexcept.h, libpng, and zlib.
  Added consideration of "zopfli" compression to the "To do" \ 
list.
  Fixed a typo that caused a cHRM chunk to be "found" if an iCCP chunk
    were present.
  Reset best_byte_count before trial loop.
  Revise global png_set_keep_unknown_chunks() calls to avoid a libpng16
    warning.
  Reset "intent" to "specified_intent" before trial loop.
  Reset "plte_len" to "specified_plte_len" before trial loop.
  Initialize length of each trial to 0x7fffffff so any untried method
    is not the "best method".

Log message:
Changes 1.7.50:
* Removed completed items from the "To do" list.
* Ignore the argument of the "plte_len" argument and just set the
     "reduce_palette" flag.
