-Libpng 1.0.8beta2 - July 10, 2000
+Libpng 1.0.9beta6 - December 18, 2000

 This is a public release of libpng, intended for use in production codes.

-Changes since the last public release (1.0.6):
-
-  Changed sprintf() to strcpy() in png_write_sCAL_s() to work without STDIO
-  Added data_length parameter to png_decompress_chunk() function
-  Revised documentation to remove reference to abandoned png_free_chnk functions
-  Fixed an error in png_rgb_to_gray_fixed()
-  Revised example.c, usage of png_destroy_write_struct().
-  Renamed makefile.ibmvac3 to makefile.ibmc, added libpng.icc IBM project file
-  Added a check for info_ptr->free_me&PNG_FREE_TEXT when free'ing text in png.c
-  Simplify png_sig_bytes() function to remove use of non-ISO-C strdup().
-  Added png_data_freer() function.
-  In the code that checks for over-length tRNS chunks, added check of
-    info_ptr->num_trans as well as png_ptr->num_trans (Matthias Benckmann)
-  Check for existing data and free it if the free_me flag is set, in png_set_*()
-    and png_handle_*().
-  Only define PNG_WEIGHTED_FILTERS_SUPPORTED when PNG_FLOATING_POINT_SUPPORTED
-    is defined.
-  Changed several instances of PNG_NO_CONSOLE_ID to PNG_NO_STDIO in pngrutil.c
-    and mentioned the purposes of the two macros in libpng.txt/libpng.3.
-  Revised png_set_iCCP() and png_set_rows() to avoid prematurely freeing data.
-  Add checks in png_set_text() for NULL members of the input text structure.
-  Removed superfluous prototype for png_set_itxt from png.h
-  Removed "else" from pngread.c, after png_error(), and changed "0" to "length".
-  Changed several png_errors about malformed ancillary chunks to png_warnings.
-  Added png_pass-* arrays to pnggccrd.c when PNG_USE_LOCAL_ARRAYS is defined.
-  Relocated paragraph about png_set_background() in libpng.3/libpng.txt
-    and other revisions (Matthias Benckmann)
-  Relocated info_ptr->free_me to restore binary compatibility with libpng-1.0.5
-    (breaks compatibility with libpng-1.0.6).
-  Relocated info_ptr->free_me, png_ptr->free_me, and other info_ptr and
-    png_ptr members to restore binary compatibility with libpng-1.0.5
-    (breaks compatibility with libpng-1.0.6).
-  Rearranged some members at the end of png_info and png_struct, to put
-    unknown_chunks_num and free_me within the original size of the png_structs
-    and free_me, png_read_user_fn, and png_free_fn within the original png_info,
-    because some old applications allocate the structs directly instead of
-    using png_create_*().
-  Added documentation of user memory functions in libpng.txt/libpng.3
-  Modified png_read_png so that it will use user_allocated row_pointers
-    if present, unless free_me directs that it be freed, and added description
-    of the use of png_set_rows() and png_get_rows() in libpng.txt/libpng.3.
-  Added PNG_LEGACY_SUPPORTED macro, and #ifdef out all new (since version
-    1.00) members of png_struct and png_info, to regain binary compatibility
-    when you define this macro.  Capabilities lost in this event
-    are user transforms (new in version 1.0.0),the user transform pointer
-    (new in version 1.0.2), rgb_to_gray (new in 1.0.5), iCCP, sCAL, sPLT,
-    the high-level interface, and unknown chunks support (all new in 1.0.6).
-    This was necessary because of old applications that allocate the structs
-    directly as authors were instructed to do in libpng-0.88 and earlier,
-    instead of using png_create_*(). 
-  Added makefile.intel and updated makefile.watcom (Pawel Mrochen)
-  Overloaded png_read_init() and png_write_init() with macros that convert
-    calls to png_read_init_2() or png_write_init_2() that check the version
-    and structure sizes.
-  Made PNG_NO_ITXT_SUPPORTED the default setting, to avoid memory overrun
-    when old applications fill the info_ptr->text structure directly.
-  Added PNGAPI macro, and added it to the definitions of all exported functions.
-  Relocated version macro definitions ahead of the includes of zlib.h and
-    pngconf.h in png.h.
-  Made PNG_NO_CONSOLE_IO the default condition when PNG_BUILD_DLL is defined.
-  Use MSC _RPTn debugging instead of fprintf if _MSC_VER is defined.
-  Added png_access_version_number() function.
-  Check for mask&PNG_FREE_CHNK (for TEXT, SCAL, PCAL) in png_free_data().
-  Expanded libpng.3/libpng.txt information about png_data_freer().
-  Changed pnggccrd.c and pngvcrd.c to handle bad adaptive filter types as
-    warnings instead of errors, as pngrutil.c does.
-  Set the PNG_INFO_IDAT valid flag in png_set_rows() so png_write_png()
-    will actually write IDATs.
-  Made the default PNG_USE_LOCAL_ARRAYS depend on PNG_DLL instead of WIN32.
-  Make png_free_data() ignore its final parameter when freeing data that can
-    have multiple instances (text, sPLT, unknowns).
-  Removed info_ptr->valid tests from png_free_data(), as in version 1.0.5.
-  Added png_set_invalid() function.
-  Fixed incorrect illustrations of png_destroy_write_struct() in example.c.
-  Revised the deliberately erroneous Linux setjmp code in pngconf.h to produce
-    fewer error messages.
-  Set each pointer to NULL after freeing it in png_free_data().
-  Worked around a problem in pngconf.h; AIX's strings.h defines an "index"
-    macro that conflicts with libpng's png_color_16.index. (Dimitri Papadapoulos)
-  Added PNG_NO_POINTER_INDEXING macro to use array-indexing instead of pointer
-    indexing in pngrutil.c and pngwutil.c to accommodate a buggy compiler.
-  Added a check for overlength PLTE chunk in pngrutil.c.
-  Added PNG_NO_POINTER_INDEXING macro to use array-indexing instead of pointer
-    indexing in pngrutil.c and pngwutil.c to accommodate a buggy compiler.
-  Added a warning in png_decompress_chunk() when it runs out of data.
-  Revised the copyright/disclaimer/license notice.
-  Corrected the definition of PNG_TRANSFORM_INVERT_ALPHA  (0x0400 not 0x0200)
-  Added PNG_USE_DLL macro.
-  Added "msvc" and contrib/msvctest directories with MSVC++ project files
-    (Simon-Pierre Cadieux) and contrib/visupng directory (Willem van Schaik).
-  Removed leading underscores from "_PNG_H" and "_PNG_SAVE_BSD_SOURCE" macros.
-  Fixed bugs in pngwrite.c and pngwutil.c that prevented writing iCCP chunks.
-  Revised the definition of "trans_values" in libpng.3/libpng.txt
-  Added png_free(png_ptr, key) two places in pngpread.c to stop memory leaks.
-  Changed PNG_NO_STDIO to PNG_NO_CONSOLE_IO, several places in pngrutil.c and
-     pngwutil.c.
-  Changed PNG_EXPORT_VAR to use PNG_IMPEXP, in pngconf.h.
-  Removed unused "#include <assert.h>" from png.c
-  Added WindowsCE support.
-  Revised pnggccrd.c to work with gcc-2.95.2 and in the Cygwin environment.

+
+The MNG specification (available at http://www.libpng.org/pub/mng) allows

+
+   feature_set = png_permit_mng_features(png_ptr, mask)
+   mask is a png_uint_32 containing the logical OR of the

+   feature_set is a png_32_uint that is the logical AND of
+      your mask with the set of MNG features that is
+      supported by the version of libpng that you are using.
+
+It is an error to use this function when reading or writing a standalone
+PNG file with the PNG 8-byte signature.  The PNG datastream must be wrapped
+in a MNG datastream (as a minimum, it must have the MNG 8-byte signature
+and the MHDR and MEND chunks).

+Project files to build libpng using Borland C++ Builder v5.0
+
+To use this dll, you will need to:
+
+1) add the following conditional defines to your project
+
+PNG_USE_DLL
+Z_PREFIX
+
+2) add the paths to png.h and zlib.h to your include path
+
+3) add libpng.lib or libpngstat.lib to the project.
+
+If you are using libpng.dll, libpng.dll and zlib.dll will be required for the code to run.
+
+Alternatively, the libpng.dll can be built using zlibstat.lib to produce one dll containing both the zlib and png code.
+
+See the libpng documentation for instructions on how to use the code.

+//   Important note about DLL memory management when your DLL uses the
+//   static version of the RunTime Library:
+//
+//   If your DLL exports any functions that pass String objects (or structs/
+//   classes containing nested Strings) as parameter or function results,
+//   you will need to add the library MEMMGR.LIB to both the DLL project and
+//   any other projects that use the DLL.  You will also need to use MEMMGR.LIB
+//   if any other projects which use the DLL will be performing new or delete
+//   operations on any non-TObject-derived classes which are exported from the
+//   DLL. Adding MEMMGR.LIB to your project will change the DLL and its calling
+//   EXE's to use the BORLNDMM.DLL as their memory manager.  In these cases,
+//   the file BORLNDMM.DLL should be deployed along with your DLL.
+//
+//   To avoid using BORLNDMM.DLL, pass string information using "char *" or
+//   ShortString parameters.
+//
+//   If your DLL uses the dynamic version of the RTL, you do not need to
+//   explicitly add MEMMGR.LIB as this will be done implicitly for you
