Fixed bug (introduced in libpng-1.0.5h) with handling zero-length
version 1.2.27 [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.
Reject tRNS chunk with out-of-range samples instead of masking off
the invalid high bits as done in since libpng-1.2.19beta5.
version 1.2.27beta02 [April 13, 2008]
Revised documentation about unknown chunk and user chunk handling.
Keep tRNS chunk with out-of-range samples and issue a png_warning().
version 1.2.27beta03 [April 14, 2008]
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.
version 1.2.27beta04 [April 18, 2008]
Added AC_LIBTOOL_WIN32_DLL to configure.ac

Y2K compliance in libpng:
=========================
April 23, 2008
April 30, 2008
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 1.2.27rc01 are Y2K compliant. It is my belief that earlier
upward through 1.2.27 are Y2K compliant. It is my belief that earlier
versions were also Y2K compliant.
Libpng only has three year fields. One is a 2-byte unsigned integer
