+
+version 1.4.0beta88 [October 30, 2009]
+  Revised libpng*.txt section about differences between 1.2.x and 1.4.0
+    because most of the new features have now been ported back to 1.2.41
+
+version 1.4.0beta89 [November 1, 2009]
+  More bugfixes and improvements to CMakeLists.txt (Philip Lowman)
+  Removed a harmless extra png_set_invert_alpha() from pngwrite.c

+  Added PNG_DEPSTRUCT, PNG_DEPRECATED, PNG_USE_RESULT, PNG_NORETURN, and

+  Updated scripts/makefile* to add "-DPNG_CONFIGURE_LIBPNG" to CFLAGS,
+    to prevent warnings about direct access to png structs by libpng
+    functions while building libpng.  They need to be tested, especially
+    those using compilers other than gcc.
+  Updated projects/visualc6 and visualc71 with "/d PNG_CONFIGURE_LIBPNG".
+    They should work but still need to be updated to remove
+    references to pnggccrd.c or pngvcrd.c and ASM building.
+  Added README.txt to the beos, cbuilder5, netware, and xcode projects warning

+  Revised Makefile.in
+
+version 1.4.0beta98 [November 13, 2009]
+  Added the "xcode" project to zip distributions,
+  Fixed a typo in scripts/pngwin.def introduced in beta97.
+
+version 1.4.0beta99 [November 14, 2009]
+  Moved libpng-config.in and libpng.pc-configure.in out of the scripts
+    directory, to libpng-config.in and libpng-pc.in, respectively, and

+  Removed obsolete comments about ASM from projects/visualc71/README_zlib.txt
+  Align row_buf on 16-byte boundary in memory.
+  Restored the PNG_WRITE_FLUSH_AFTER_IEND_SUPPORTED guard around the call
+    to png_flush() after png_write_IEND().  See 1.4.0beta32, 1.4.0beta50
+    changes above and 1.2.30, 1.2.30rc01 and rc03 in 1.2.41 CHANGES.  Someone
+    needs this feature.

+    jmp_buf buffer, and marked direct access to jmpbuf 'deprecated'.
+    (John Bowler)
+
+version 1.4.0beta104 [November 22, 2009]
+  Removed png_longjmp_ptr from scripts/*.def and libpng.3

+  Added "#define PNG_NO_PEDANTIC_WARNINGS" in the libpng source files.
+  Removed "-DPNG_CONFIGURE_LIBPNG" from the makefiles and projects.
+  Revised scripts/makefile.netbsd, makefile.openbsd, and makefile.sco
+    to put png.h and pngconf.h in $prefix/include, like the other scripts,
+    instead of in $prefix/include/libpng.  Also revised makefile.sco
+    to put them in $prefix/include/libpng15 instead of in
+    $prefix/include/libpng/libpng15.
+
+version 1.4.0beta108 [December 11, 2009]
+  Removed leftover "-DPNG_CONFIGURE_LIBPNG" from contrib/pngminim/*/makefile
+  Relocated png_do_chop() to its original position in pngrtran.c; the
+    change in version 1.2.41beta08 caused transparency to be handled wrong
+    in some 16-bit datastreams (Yusaku Sugai).
+
+version 1.4.0beta109 [December 13, 2009]
+  Added "bit_depth" parameter to the private png_build_gamma_table() function.
+  Pass bit_depth=8 to png_build_gamma_table() when bit_depth is 16 but the
+    PNG_16_TO_8 transform has been set, to avoid unnecessary build of 16-bit
+    tables.
+
+version 1.4.0rc02 [December 20, 2009]
+  Declared png_cleanup_needed "volatile" in pngread.c and pngwrite.c
+
+version 1.4.0rc03 [December 22, 2009]
+  Renamed libpng-pc.in back to libpng.pc.in and revised CMakeLists.txt

+
+version 1.4.0rc04 [December 25, 2009]

+
+version 1.4.0rc05 [December 25, 2009]

+  Make png_set|get_compression_buffer_size() available even when
+    PNG_WRITE_SUPPORTED is not enabled.
+  Revised Makefile.am and Makefile.in to simplify their maintenance.
+  Revised scripts/makefile.linux to install a link to libpng14.so.14.1

+  Added defineable PNG_USER_CHUNK_CACHE_MAX, PNG_USER_CHUNK_MALLOC_MAX,
+    and a PNG_USER_LIMITS_SUPPORTED flag.
+  Eliminated use of png_ptr->irowbytes and reused the slot in png_ptr as
+    png_ptr->png_user_chunk_malloc_max.
+  Revised png_push_save_buffer() to do fewer but larger png_malloc() calls.

+deprecated since libpng-1.0.18 and 1.2.9, when it was replaced with
+png_set_expand_gray_1_2_4_to_8() because the former function also
+expanded palette images.
 
 We changed the prototype for png_malloc() from

-
-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.

+ * that the application can find out the characteristics of the image.
+ * If you are reading the file, this structure will tell you what is
+ * in the PNG file.  If you are writing the file, fill in the information
+ * you want to put into the PNG file, using png_set_*() functions, then
+ * call png_write_info().
+ *
+ * The names chosen should be very close to the PNG specification, so
+ * consult that document for information about the meaning of each field.
+ *
+ * With libpng < 0.95, it was only possible to directly set and read the
+ * the values in the png_info_struct, which meant that the contents and
+ * order of the values had to remain fixed.  With libpng 0.95 and later,
+ * however, there are now functions that abstract the contents of
+ * png_info_struct from the application, so this makes it easier to use
+ * libpng with dynamic libraries, and even makes it possible to use
+ * libraries that don't have all of the libpng ancillary chunk-handing
+ * functionality.  In libpng-1.5.0 this was moved into a separate private
+ * file that is not visible to applications.
+ *
+ * The following members may have allocated storage attached that should be
+ * cleaned up before the structure is discarded: palette, trans, text,
+ * pcal_purpose, pcal_units, pcal_params, hist, iccp_name, iccp_profile,
+ * splt_palettes, scal_unit, row_pointers, and unknowns.   By default, these
+ * are automatically freed when the info structure is deallocated, if they were
+ * allocated internally by libpng.  This behavior can be changed by means
+ * of the png_data_freer() function.
+ *
+ * More allocation details: all the chunk-reading functions that
+ * change these members go through the corresponding png_set_*
+ * functions.  A function to clear these members is available: see
+ * png_free_data().  The png_set_* functions do not depend on being
+ * able to point info structure members to any of the storage they are
+ * passed (they make their own copies), EXCEPT that the png_set_text
+ * functions use the same storage passed to them in the text_ptr or
+ * itxt_ptr structure argument, and the png_set_rows and png_set_unknowns
+ * functions do not make their own copies.

-//   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

-Project files to build libpng using Borland C++ Builder v5.0
-
-In order to build and use libpng, please follow these steps:
-
- 1). Install zlib in a directory at the same level with libpng.
-
- 2). In a console window, go to the zlib directory and type:
-       make -f win32\Makefile.bor
-     After performing this step, you should have a file named
-     zlib.lib in the zlib directory.
-
- 3). Add the following conditional define to your project:
-       PNG_USE_DLL
-
- 4). Add libpng.lib or libpngstat.lib to the project.
-     Build the project.
-
- 5). If the build fails, add the paths to png.h and zlib.h to
-     your include path, and restart the build.
-
-By default, the libpng project uses zlib as a static library.  If
-you wish to use zlib as a DLL, please read the important notes from
-the zlib DLL FAQ, found inside the zlib distribution.
-
-See the libpng documentation for instructions on how to use the code.
