-1.0.1 (May 2nd 2001)
---------------------
-
-in short:
-
-Maintenance release.
-Fixed several memory-leaks with the help of Gregg Kelly, added/fixed some CMS
-handling, exported JPEG functions from standard DLL, and some other minor fixes.
-
-The CMS fix now makes libmng automagically work in MNG_FULL_CMS mode as a 
-sRGB compliant system. YOU WILL NEED TO CHANGE THIS IF YOU ARE NOT ON AN sRGB
-COMPLIANT SYSTEM AND WANT TO USE CMS!!!!
-(look in libmng.h for the proper function-calls)
-
--------------------
-
-bugfixes:
-
-core:
-- added MEND processing callback                           
-- fixed first FRAM_MODE=4 timing problem                  
-- added handle status-copy function (use with care)
-- exported JPEG functions from standard DLL
-- added BGRA8 canvas with premultiplied alpha (contrib by Gregg Kelly)
-- fixed problem with display_reset/display_resume (Thanks Gregg!)
-- fixed several memory-leaks (Thanks Gregg!)
-- fixed reset_rundata to drop all objects (Thanks again, Gregg!)
-- fixed problem with cms profile being created multiple times when both
-  iCCP & cHRM/gAMA are present (And again... Gregg)
-- moved mng_clear_cms to libmng_cms

-1.0.0 (Feb 6th 2001)
---------------------
-
-in short:
-
-First public release. Finally(!)
-
-This is the 0.9.5 CVS version, which will never be released, because I feel it
-is now ready for a public release. So apart from the version-numbers here and
-there, all other changes are listed under 0.9.5.
-
-This library will work with every MNG/JNG known and available to me. Note that
-there are still parts that need to be coded, and that MNG support is around
-90-95% (JNG at 100%). It is however compliant with the latest and greatest
-MNG 1.0 specification.
-
-I hope to dedicate a bit more time this year to finish up full support and fill
-in the remaining blanks. But this is coming out of my spare time. And extra
-help is always appreciated.
-
-Please enjoy!

-libmng 1.0.1
-------------
-
-First maintenance release!
-
-There's been some changes in the CMS profile handling, that should make it
-easier for sRGB-compliant systems. Non-sRGB compliant systems will still need
-some extra work if they want to use MNG_FULL_CMS with lcms. But this has always
-been so, so it's not an extra step anyway.
-(Many thanks to Marti, Ivan & Warwick for their help & comments!)
-
-Gregg Kelly has been helpful in locating a couple of memory-leaks, and make
-the library even better.
-
-The default Windows DLL that's part of the Windows zip-files now also exports
-the JPEG library function calls (ijgsrc6b). Note that there's a new Delphi
-component (TNGImage) that makes it a snap to work with PNG/JNG & MNG images
-within Delphi.
-
-Please enjoy!

-version 0.81 [August, 1995]
-  incorporated Tim Wegner's medium model code (thanks, Tim)
-version 0.82 [September, 1995]
-  [unspecified changes]
-version 0.85 [December, 1995]
-  added more medium model code (almost everything's a far)
-  added i/o, error, and memory callback functions
-  fixed some bugs (16 bit, 4 bit interlaced, etc.)
-  added first run progressive reader (barely tested)
-version 0.86 [January, 1996]
-  fixed bugs
-  improved documentation
-version 0.87 [January, 1996]
-  fixed medium model bugs
-  fixed other bugs introduced in 0.85 and 0.86
-  added some minor documentation
-version 0.88 [January, 1996]
-  fixed progressive bugs
-  replaced tabs with spaces
-  cleaned up documentation
-  added callbacks for read/write and warning/error functions
-version 0.89 [July, 1996]
-  added new initialization API to make libpng work better with shared libs
-     we now have png_create_read_struct(), png_create_write_struct(),
-     png_create_info_struct(), png_destroy_read_struct(), and
-     png_destroy_write_struct() instead of the separate calls to
-     malloc and png_read_init(), png_info_init(), and png_write_init()
-  changed warning/error callback functions to fix bug - this means you
-     should use the new initialization API if you were using the old
-     png_set_message_fn() calls, and that the old API no longer exists
-     so that people are aware that they need to change their code
-  changed filter selection API to allow selection of multiple filters
-     since it didn't work in previous versions of libpng anyways
-  optimized filter selection code
-  fixed png_set_background() to allow using an arbitrary RGB color for
-     paletted images
-  fixed gamma and background correction for paletted images, so
-     png_correct_palette is not needed unless you are correcting an
-     external palette (you will need to #define PNG_CORRECT_PALETTE_SUPPORTED
-     in pngconf.h) - if nobody uses this, it may disappear in the future.
-  fixed bug with Borland 64K memory allocation (Alexander Lehmann)
-  fixed bug in interlace handling (Smarasderagd, I think)
-  added more error checking for writing and image to reduce invalid files
-  separated read and write functions so that they won't both be linked
-     into a binary when only reading or writing functionality is used
-  new pngtest image also has interlacing and zTXt
-  updated documentation to reflect new API
-version 0.90 [January, 1997]
-  made CRC errors/warnings on critical and ancillary chunks configurable
-  libpng will use the zlib CRC routines by (compile-time) default
-  changed DOS small/medium model memory support - needs zlib 1.04 (Tim Wegner)
-  added external C++ wrapper statements to png.h (Gilles Dauphin)
-  allow PNG file to be read when some or all of file signature has already
-     been read from the beginning of the stream.  ****This affects the size
-     of info_struct and invalidates all programs that use a shared libpng****
-  fixed png_filler() declarations
-  fixed? background color conversions
-  fixed order of error function pointers to match documentation
-  current chunk name is now available in png_struct to reduce the number
-     of nearly identical error messages (will simplify multi-lingual
-     support when available)
-  try to get ready for unknown-chunk callback functions:
-     - previously read critical chunks are flagged, so the chunk handling
-       routines can determine if the chunk is in the right place
-     - all chunk handling routines have the same prototypes, so we will
-       be able to handle all chunks via a callback mechanism
-  try to fix Linux "setjmp" buffer size problems
-  removed png_large_malloc, png_large_free, and png_realloc functions.
-version 0.95 [March, 1997]
-  fixed bug in pngwutil.c allocating "up_row" twice and "avg_row" never
-  fixed bug in PNG file signature compares when start != 0
-  changed parameter type of png_set_filler(...filler...) from png_byte
-     to png_uint_32
-  added test for MACOS to ensure that both math.h and fp.h are not #included
-  added macros for libpng to be compiled as a Windows DLL (Andreas Kupries)
-  added "packswap" transformation, which changes the endianness of
-     packed-pixel bytes (Kevin Bracey)
-  added "strip_alpha" transformation, which removes the alpha channel of
-     input images without using it (not neccesarily a good idea)
-  added "swap_alpha" transformation, which puts the alpha channel in front
-     of the color bytes instead of after
-  removed all implicit variable tests which assume NULL == 0 (I think)
-  changed several variables to "png_size_t" to show 16/32-bit limitations
-  added new pCAL chunk read/write support
-  added experimental filter selection weighting (Greg Roelofs)
-  removed old png_set_rgbx() and png_set_xrgb() functions that have been
-     obsolete for about 2 years now (use png_set_filler() instead)
-  added macros to read 16- and 32-bit ints directly from buffer, to be
-     used only on those systems that support it (namely PowerPC and 680x0)
-     With some testing, this may become the default for MACOS/PPC systems.
-  only calculate CRC on data if we are going to use it
-  added macros for zTXt compression type PNG_zTXt_COMPRESSION_???
-  added macros for simple libpng debugging output selectable at compile time
-  removed PNG_READ_END_MODE in progressive reader (Smarasderagd)
-  more description of info_struct in libpng.txt and png.h
-  more instructions in example.c
-  more chunk types tested in pngtest.c

-    png_get_spalettes, png_set_iCCP, png_set_spalettes (Eric S. Raymond).
-  NOTE: Applications that write text chunks MUST define png_text->lang
-    before calling png_set_text(). It must be set to NULL if you want to
-    write tEXt or zTXt chunks.  If you want your application to be able to
-    run with older versions of libpng, use

-    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.

-  Relocated paragraph about png_set_background() in libpng.3/libpng.txt
-    and other revisions (Matthias Benckmann)
-  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).
-version 1.0.6h [April 24, 2000]
-  Changed shared library so-number pattern from 2.x.y.z to xy.z (this builds
-    libpng.so.10 & libpng.so.10.6h instead of libpng.so.2 & libpng.so.2.1.0.6h)

-version 1.0.6i [May 2, 2000]
-  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

-  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 modes PNG_CREATED_READ_STRUCT and PNG_CREATED_WRITE_STRUCT which
-    can be used to detect codes that directly allocate the structs, and
-    code to check these modes in png_read_init() and png_write_init() and
-    generate a libpng error if the modes aren't set and PNG_LEGACY_SUPPORTED
-    was not defined.
-  Added makefile.intel and updated makefile.watcom (Pawel Mrochen)
-version 1.0.6j [May 3, 2000]

-    and structure sizes.
-version 1.0.7beta11 [May 7, 2000]
-  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
-    or PNG_LEGACY_SUPPORTED is defined.
-  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.
-version 1.0.7beta12 [May 12, 2000]

-  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().
-version 1.0.7beta14 [May 17, 2000] (beta13 was not published)
-  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 except when freeing data
-    that can have multiple instances (text, sPLT, unknowns).
-  Fixed a new bug in png_set_rows().
-  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.
-version 1.0.7beta15 [May 30, 2000]
-  Revised the deliberately erroneous Linux setjmp code in pngconf.h to produce
-    fewer error messages.
-  Rearranged checks for Z_OK to check the most likely path first in pngpread.c
-    and pngwutil.c.
-  Added checks in pngtest.c for png_create_*() returning NULL, and mentioned
-    in libpng.txt/libpng.3 the need for applications to check this.
-  Changed names of png_default_*() functions in pngtest to pngtest_*().
-  Changed return type of png_get_x|y_offset_*() from png_uint_32 to png_int_32.
-  Fixed some bugs in the unused PNG_INCH_CONVERSIONS functions in pngget.c
-  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 "msvc" directory with MSVC++ project files (Simon-Pierre Cadieux).
-version 1.0.7beta16 [June 4, 2000]
-  Revised the workaround of AIX string.h "index" bug.
-  Added a check for overlength PLTE chunk in pngrutil.c.

-  Revised the copyright/disclaimer/license notice.
-  Added contrib/msvctest directory

-README for libpng 1.0.9 - January 31, 2001 (shared library 2.1)
-See the note about version numbers near the top of png.h
-
-See INSTALL for instructions on how to install libpng.
-
-Libpng comes in two distribution formats.  Get libpng-*.tar.gz if you
-want UNIX-style line endings in the text files, or lpng*.zip if you want
-DOS-style line endings.
-
-Version 0.89 was the first official release of libpng.  Don't let the
-fact that it's the first release fool you.  The libpng library has been in
-extensive use and testing since mid-1995.  By late 1997 it had
-finally gotten to the stage where there hadn't been significant
-changes to the API in some time, and people have a bad feeling about
-libraries with versions < 1.0.  Version 1.0.0 was released in
-March 1998.
-
-****
-Note that some of the changes to the png_info structure render this
-version of the library binary incompatible with libpng-0.89 or
-earlier versions if you are using a shared library.  The type of the
-"filler" parameter for png_set_filler() has changed from png_byte to
-png_uint_32, which will affect shared-library applications that use
-this function.
-
-To avoid problems with changes to the internals of png_info_struct,
-new APIs have been made available in 0.95 to avoid direct application
-access to info_ptr.  These functions are the png_set_<chunk> and
-png_get_<chunk> functions.  These functions should be used when
-accessing/storing the info_struct data, rather than manipulating it
-directly, to avoid such problems in the future.
-
-It is important to note that the APIs do not make current programs
-that access the info struct directly incompatible with the new
-library.  However, it is strongly suggested that new programs use
-the new APIs (as shown in example.c and pngtest.c), and older programs
-be converted to the new format, to facilitate upgrades in the future.
-****
-
-Additions since 0.90 include the ability to compile libpng as a
-Windows DLL, and new APIs for accessing data in the info struct.
-Experimental functions include the ability to set weighting and cost
-factors for row filter selection, direct reads of integers from buffers
-on big-endian processors that support misaligned data access, faster
-methods of doing alpha composition, and more accurate 16->8 bit color
-conversion.
-
-The additions since 0.89 include the ability to read from a PNG stream
-which has had some (or all) of the signature bytes read by the calling
-application.  This also allows the reading of embedded PNG streams that
-do not have the PNG file signature.  As well, it is now possible to set
-the library action on the detection of chunk CRC errors.  It is possible
-to set different actions based on whether the CRC error occurred in a
-critical or an ancillary chunk.
-
-The changes made to the library, and bugs fixed are based on discussions
-on the PNG implementation mailing list <png-implement@ccrc.wustl.edu>
-and not on material submitted privately to Guy, Andreas, or Glenn.  They will
-forward any good suggestions to the list.
-
-For a detailed description on using libpng, read libpng.txt.  For
-examples of libpng in a program, see example.c and pngtest.c.  For usage
-information and restrictions (what little they are) on libpng, see
-png.h.  For a description on using zlib (the compression library used by
-libpng) and zlib's restrictions, see zlib.h
-
-I have included a general makefile, as well as several machine and
-compiler specific ones, but you may have to modify one for your own needs.
-
-You should use zlib 1.0.4 or later to run this, but it MAY work with
-versions as old as zlib 0.95.  Even so, there are bugs in older zlib
-versions which can cause the output of invalid compression streams for
-some images.  You will definitely need zlib 1.0.4 or later if you are
-taking advantage of the MS-DOS "far" structure allocation for the small
-and medium memory models.  You should also note that zlib is a
-compression library that is useful for more things than just PNG files.
-You can use zlib as a drop-in replacement for fread() and fwrite() if
-you are so inclined.
-
-zlib should be available at the same place that libpng is.
-If not, it should be at ftp.uu.net in /graphics/png
-Eventually, it will be at ftp.uu.net in /pub/archiving/zip/zlib
-
-You may also want a copy of the PNG specification.  It is available
-as an RFC and a W3C Recommendation.  Failing
-these resources you can try ftp.uu.net in the /graphics/png directory.
-
-This code is currently being archived at ftp.uu.net in the
-/graphics/png directory, and on CompuServe, Lib 20 (PNG SUPPORT)
-at GO GRAPHSUP.  If you can't find it in any of those places,
-e-mail me, and I'll help you find it.
-
-If you have any code changes, requests, problems, etc., please e-mail
-them to me.  Also, I'd appreciate any make files or project files,
-and any modifications you needed to make to get libpng to compile,
-along with a #define variable to tell what compiler/system you are on.
-If you needed to add transformations to libpng, or wish libpng would
-provide the image in a different way, drop me a note (and code, if
-possible), so I can consider supporting the transformation.
-Finally, if you get any warning messages when compiling libpng
-(note: not zlib), and they are easy to fix, I'd appreciate the
-fix.  Please mention "libpng" somewhere in the subject line.  Thanks.
-
-This release was created and will be supported by myself (of course
-based in a large way on Guy's and Andreas' earlier work), and the PNG group.
-
-randeg@alum.rpi.edu
-png-implement@ccrc.wustl.edu
-
-You can't reach Guy, the original libpng author, at the addresses
-given in previous versions of this document.  He and Andreas will read mail
-addressed to the png-implement list, however.
-
-Please do not send general questions about PNG.  Send them to
-the address in the specification (png-group@w3.org).  At the same
-time, please do not send libpng questions to that address, send them to me
-or to png-implement@ccrc.wustl.edu.  I'll
-get them in the end anyway.  If you have a question about something
-in the PNG specification that is related to using libpng, send it
-to me.  Send me any questions that start with "I was using libpng,
-and ...".  If in doubt, send questions to me.  I'll bounce them
-to others, if necessary.
-
-Please do not send suggestions on how to change PNG.  We have
-been discussing PNG for three years now, and it is official and
-finished.  If you have suggestions for libpng, however, I'll
-gladly listen.  Even if your suggestion is not used for version
-1.0, it may be used later.
