-Known bugs in libpng version 1.2.41beta19
-
-1. February 23, 2006: The custom makefiles don't build libpng with -lz.
-
-   STATUS: This is a subject of debate. The change will probably be made
-   as a part of a major overhaul of the makefiles in libpng version 1.4.0.
-
-2. February 24, 2006: The Makefile generated by the "configure" script
-   fails to install symbolic links
-   libpng12.so => libpng12.so.0.1.2.9betaN
-   that are generated by the custom makefiles.
-
-3. September 4, 2007:  There is a report that pngtest crashes on MacOS 10.
-
-   STATUS: workarounds are
-      1) Compile without optimization (crashes are observed with
-         -arch i386 and -O2 or -O3, using gcc-4.0.1).
-      2) Compile pngtest.c with PNG_DEBUG defined (the bug goes away if
-         you try to look at it).
-      3) Ignore the crash.  The library itself seems to be OK.

-   Y2K compliance in libpng:
-   =========================
-
-      November 11, 2009
-
-      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 1.2.41beta19 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
-      that will hold years up to 65535.  The other two hold the date in text
-      format, and will hold years up to 9999.
-
-      The integer is
-          "png_uint_16 year" in png_time_struct.
-
-      The strings are
-          "png_charp time_buffer" in png_struct and
-          "near_time_buffer", which is a local character string in png.c.
-
-      There are seven time-related functions:
-
-          png_convert_to_rfc_1123() in png.c
-            (formerly png_convert_to_rfc_1152() in error)
-          png_convert_from_struct_tm() in pngwrite.c, called in pngwrite.c
-          png_convert_from_time_t() in pngwrite.c
-          png_get_tIME() in pngget.c
-          png_handle_tIME() in pngrutil.c, called in pngread.c
-          png_set_tIME() in pngset.c
-          png_write_tIME() in pngwutil.c, called in pngwrite.c
-
-      All appear to handle dates properly in a Y2K environment.  The
-      png_convert_from_time_t() function calls gmtime() to convert from system
-      clock time, which returns (year - 1900), which we properly convert to
-      the full 4-digit year.  There is a possibility that applications using
-      libpng are not passing 4-digit years into the png_convert_to_rfc_1123()
-      function, or that they are incorrectly passing only a 2-digit year
-      instead of "year - 1900" into the png_convert_from_struct_tm() function,
-      but this is not under our control.  The libpng documentation has always
-      stated that it works with 4-digit years, and the APIs have been
-      documented as such.
-
-      The tIME chunk itself is also Y2K compliant.  It uses a 2-byte unsigned
-      integer to hold the year, and can hold years as large as 65535.
-
-      zlib, upon which libpng depends, is also Y2K compliant.  It contains
-      no date-related code.

-IX.  (Omitted)
+IX.  Changes to Libpng from version 1.0.x/1.2.x to 1.4.x
+
+Private libpng prototypes and macro definitions were moved from
+png.h and pngconf.h into a new pngpriv.h header file.
+
+Support for global arrays was removed.
+
+Some obsolete/deprecated macros and functions have been removed.
+
+The obsolete, unused pnggccrd.c and pngvcrd.files were removed.
+
+The PNG_1_0_X and PNG_1_2_X macros were eliminated.
+
+Functions png_set_benign_errors(), png_benign_error(), and
+png_chunk_benign_error() were added.
+
+Support for setting the maximum amount of memory that the application
+will allocate for reading chunks was added, as a security measure.
+The functions png_set_chunk_cache_max() and png_get_chunk_cache_max()
+were added to the library.
+
+We implemented support for I/O states by adding png_ptr member io_state
+and functions png_get_io_chunk_name() and png_get_io_state() in pngget.c
+
+The png_calloc() function was added and is used in place of
+of "png_malloc(); png_memset();" except in the case in png_read_png()
+where the array consists of pointers; in this case a "for" loop is used
+after the png_malloc() to set the pointers to NULL.
+
+We added PNG_TRANSFORM_GRAY_TO_RGB to the available high-level
+input transforms.
+
+We added the png_set_premultiply_alpha and
+png_do_read_premultiply_alpha() functions.
+
+The call to png_do_chop() in pngrtran.c, which reduces 16-bit input
+files to 8-bit bit depth, was relocated ahead of the building
+of gamma tables.  This allows us to build 8-bit tables instead
+of 16-bit tables, when only 8-bit tables are needed. This avoids 
+wasting some computing resources when the application has called
+the png_set_strip_16() function and encounters a 16-bit PNG file.
+
+Checking for and reporting of errors in the IHDR chunk is more thorough.
+
+The PNG_LEGACY_SUPPORTED macro was eliminated.
+
+Many WIN32_WCE #ifdefs were removed.
+
+The functions png_read_init(info_ptr), png_write_init(info_ptr),
+png_info_init(info_ptr), png_read_destroy(), and png_write_destroy()
+have been removed.  They have been deprecated since libpng-0.95.
+
+Support for numbered error messages was removed by default, since we
+never got around to actually numbering the error messages. The function
+png_set_strip_error_numbers() was removed from the library by default.
+
+The png_permit_empty_plte() was removed. It has been deprecated
+since libpng-1.0.9.  Use png_permit_mng_features() instead.
+
+We removed the obsolete stub functions png_get_mmx_flagmask(),
+png_set_mmx_thresholds(), png_get_asm_flags(),
+png_get_mmx_bitdepth_threshold(), png_get_mmx_rowbytes_threshold(),
+png_set_asm_flags(), and png_mmx_supported()
+
+We removed the png_check_sig(), png_memcpy_check(), and
+png_memset_check() functions.
+
+We changed the prototype for png_malloc() from
+    png_malloc(png_structp png_ptr, png_uint_32 size)
+to
+    png_malloc(png_structp png_ptr, png_alloc_size_t size)
+
+We changed the prototypes of png_get_compression_buffer_size() and
+png_set_compression_buffer_size() to work with png_size_t instead of
+png_uint_32.
+
+The png_zalloc() function no longer zeroes out the memory that it
+allocates.
+
+The png_zalloc() and png_zfree() functions are no longer exported.
+
+We removed the trailing '.' from the warning and error messages.
+
+The png_struct and info_struct members "trans" and "trans_values" were
+changed to "trans_alpha" and "trans_color", respectively.

-.SH IX.  (Omitted)
+.SH IX.  Changes to Libpng from version 1.0.x/1.2.x to 1.4.x
+
+Private libpng prototypes and macro definitions were moved from
+png.h and pngconf.h into a new pngpriv.h header file.
+
+Support for global arrays was removed.
+
+Some obsolete/deprecated macros and functions have been removed.
+
+The obsolete, unused pnggccrd.c and pngvcrd.files were removed.
+
+The PNG_1_0_X and PNG_1_2_X macros were eliminated.
+
+Functions png_set_benign_errors(), png_benign_error(), and
+png_chunk_benign_error() were added.
+
+Support for setting the maximum amount of memory that the application
+will allocate for reading chunks was added, as a security measure.
+The functions png_set_chunk_cache_max() and png_get_chunk_cache_max()
+were added to the library.
+
+We implemented support for I/O states by adding png_ptr member io_state
+and functions png_get_io_chunk_name() and png_get_io_state() in pngget.c
+
+The png_calloc() function was added and is used in place of
+of "png_malloc(); png_memset();" except in the case in png_read_png()
+where the array consists of pointers; in this case a "for" loop is used
+after the png_malloc() to set the pointers to NULL.
+
+We added PNG_TRANSFORM_GRAY_TO_RGB to the available high-level
+input transforms.
+
+We added the png_set_premultiply_alpha and
+png_do_read_premultiply_alpha() functions.
+
+The call to png_do_chop() in pngrtran.c, which reduces 16-bit input
+files to 8-bit bit depth, was relocated ahead of the building
+of gamma tables.  This allows us to build 8-bit tables instead
+of 16-bit tables, when only 8-bit tables are needed. This avoids 
+wasting some computing resources when the application has called
+the png_set_strip_16() function and encounters a 16-bit PNG file.
+
+Checking for and reporting of errors in the IHDR chunk is more thorough.
+
+The PNG_LEGACY_SUPPORTED macro was eliminated.
+
+Many WIN32_WCE #ifdefs were removed.
+
+The functions png_read_init(info_ptr), png_write_init(info_ptr),
+png_info_init(info_ptr), png_read_destroy(), and png_write_destroy()
+have been removed.  They have been deprecated since libpng-0.95.
+
+Support for numbered error messages was removed by default, since we
+never got around to actually numbering the error messages. The function
+png_set_strip_error_numbers() was removed from the library by default.
+
+The png_permit_empty_plte() was removed. It has been deprecated
+since libpng-1.0.9.  Use png_permit_mng_features() instead.
+
+We removed the obsolete stub functions png_get_mmx_flagmask(),
+png_set_mmx_thresholds(), png_get_asm_flags(),
+png_get_mmx_bitdepth_threshold(), png_get_mmx_rowbytes_threshold(),
+png_set_asm_flags(), and png_mmx_supported()
+
+We removed the png_check_sig(), png_memcpy_check(), and
+png_memset_check() functions.
+
+We changed the prototype for png_malloc() from
+    png_malloc(png_structp png_ptr, png_uint_32 size)
+to
+    png_malloc(png_structp png_ptr, png_alloc_size_t size)
+
+We changed the prototypes of png_get_compression_buffer_size() and
+png_set_compression_buffer_size() to work with png_size_t instead of
+png_uint_32.
+
+The png_zalloc() function no longer zeroes out the memory that it
+allocates.
+
+The png_zalloc() and png_zfree() functions are no longer exported.
+
+We removed the trailing '.' from the warning and error messages.
+
+The png_struct and info_struct members "trans" and "trans_values" were
+changed to "trans_alpha" and "trans_color", respectively.

-This project builds a shared library version of libpng on x86 BeOS.
-
-It defines PNG_USE_PNGGCCRD, which activates the assembly code in
-pnggccrd.c; this hasn't been extensively tested on BeOS.
-
-To install:
-
-1) build
-
-   Note: As of version 1.0.10, you'll get a fair number of warnings when
-         you compile pnggccrd.c.  As far as I know, these are harmless,
-         but it would be better if someone fixed them.
-
-2) copy and png.h, pngconf.h somewhere; /boot/home/config/include (which
-   you'll have to make) is a good choice
-

-This project builds a static library version of libpng on x86 BeOS.

-pnggccrd.c; this hasn't been extensively tested on BeOS.

-To install:
-
-1) build

-   Note: As of version 1.0.10, you'll get a fair number of warnings when
-         you compile pnggccrd.c.  As far as I know, these are harmless,
-         but it would be better if someone fixed them.
-
-2) copy and png.h, pngconf.h somewhere; /boot/home/config/include (which
