Changes since the last public release (1.0.32):
version 1.0.32 [April 2, 2008]
version 1.0.33 [April 30, 2008]
Fixed bug (introduced in libpng-1.0.6) with handling zero-length
unknown chunks.
Added more information about png_set_keep_unknown_chunks() to the
documetation.
Revised documentation about unknown chunk and user chunk handling.
Issue a png_warning when reading a tRNS chunk with out-of-range samples.
Added check for NULL ptr in TURBOC version of png_free_default().
Removed several unnecessary checks for NULL before calling png_free().
Revised png_set_tRNS() so that calling it twice removes and invalidates
the previous call.
Revised pngtest to check for out-of-range tRNS samples.
Added AC_LIBTOOL_WIN32_DLL to configure.ac
Rebuilt Makefile.in, aclocal.m4, and configure with autoconf-2.62
Added MAINTEINERCLEANFILES variable to Makefile.am
Avoid changing color_type from GRAY to RGB by
png_set_expand_gray_1_2_4_to_8().
Fix broken URL for rfc2083 in png.5 and libpng-*.txt
Added missing "(" in pngmem.c. Bug introduced in libpng-1.2.2/1.0.13
Refined error message returned from deflateInit2 in pngwutil.c
Check IHDR length in png_push_read_chunk() before saving it.
Revised contrib/gregbook to handle premature end-of-file and file
read errors correctly.
Free png_ptr->big_row_buf and png_ptr->prev_row before allocating
new copies in png_read_start_row().
Avoid reallocating big_row_buf and prev_row when the size does not increase.
Ifdef out some code that is unused when interlacing is not supported.

Since the PNG Development group is an ad-hoc body, we can't make
an official declaration.
This is your unofficial assurance that libpng from version 0.71 and
upward through 1.0.32 are Y2K compliant. It is my belief that earlier
upward through 1.0.33 are Y2K compliant. It is my belief that earlier
versions were also Y2K compliant.
