This is a public release of libpng, intended for use in production codes.
Changes since the last public release (1.0.12):
Changes since the last public release (1.2.0):
Enabled PNG_MNG_FEATURES_SUPPORTED and enabled PNG_ASSEMBLER_CODE_SUPPORTED
by default.
Added runtime selection of MMX features.
Added png_set_strip_error_numbers function and related macros.
Enabled user memory function by default.
Increased png_mng_features flag from png_byte to png_uint_32.
Bumped shared-library (so-number) and dll-number to 3.
Updated makefile.ibmc, makefile.gcmmx
Added some typecasts to eliminate gcc 3.0 warnings. Changed prototypes
of png_write_oFFS width and height from png_uint_32 to png_int_32.
Updated example.c
Revised prototypes for png_debug_malloc and png_debug_free in pngtest.c
Revised pnggccrd.c to conditionally compile some thread-unsafe code only
when PNG_THREAD_UNSAFE_OK is defined.
Added tests to prevent pngwutil.c from writing a bKGD or tRNS chunk with
value exceeding 2^bit_depth-1
Removed restriction that do_invert_mono only operate on 1-bit opaque files
Replaced calls to fprintf(stderr,...) with png_warning() or png_debug()
in pnggccrd.c
Fixed contrib/gregbook/rpng-x.c, rpng2-x.c to avoid crash with XFreeGC().
Revised makefile.std in contrib/pngminus
Include background_1 in png_struct regardless of gamma support.
Revised makefile.netbsd and makefile.macosx, added makefile.darwin.
Revised example.c to provide more details about using row_callback().

Removed the new PNG_CREATED_READ_STRUCT and PNG_CREATED_WRITE_STRUCT modes
which are no longer used.
Eliminated the three new members of png_text when PNG_NO_iTXt_SUPPORTED

Made PNG_NO_ITXT_SUPPORTED the default setting, to avoid memory overrun

Y2K compliance in libpng:
=========================

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 1.2.0 are Y2K compliant. It is my belief that earlier
upward through 1.2.1beta1 are Y2K compliant. It is my belief that earlier
versions were also Y2K compliant.
