Belated announcement:

libpng-1.2.36 is available from
ftp://ftp.simplesystems.org/pub/png/src
and from
http://libpng.sf.net/index.html

Libpng-1.2.36 was released on May 7.
Libpng-1.2.37 will be out next Thursday June 4.

Here are the changes from 1.2.35 to 1.2.36:

 Revised comments in png_set_read_fn() and png_set_write_fn().
  Revised order of #ifdef's and indentation in png_debug definitions of png.h
    bug introduced in libpng-1.2.34.
  Use png_memset() after png_malloc() of big_row_buf when reading an
    interlaced file, to avoid a possible UMR (uninitialized memory read)
  Undid recent revision of PNG_NO_STDIO version of png_write_flush().  Users
    having trouble with fflush() can build with PNG_NO_WRITE_FLUSH defined.
  Revised libpng*.txt documentation about use of png_write_flush().
  Removed fflush() from pngtest.c.
  Added "#define PNG_NO_WRITE_FLUSH" to contrib/pngminim/encoder/pngusr.h
  Relocated misplaced PNG_1_0_X define in png.h that caused the prototype
    for png_set_strip_error_numbers() to be omitted from PNG_NO_ASSEMBLER_CODE
    builds.  This bug was introduced in libpng-1.2.15beta4.
  Added a section on differences between 1.0.x and 1.2.x to libpng.3/libpng.txt
  Fixed potential memory leak of "new_name" in png_write_iCCP() (Ralph Giles)
  Added "ifndef PNG_SKIP_SETJMP_CHECK" block in pngconf.h to allow
    application code writers to bypass the check for multiple inclusion
    of setjmp.h when they know that it is safe to ignore the situation.
  Made some cosmetic changes to whitespace in pngtest output.
  Renamed "user_chunk_data" to "my_user_chunk_data" in pngtest.c to suppress
    "shadowed declaration" warning from gcc-4.3.3.
  Renamed "gamma" to "png_gamma" in pngset.c to avoid "shadowed declaration"
    warning about a global "gamma" variable in math.h on some platforms.
