+
+version 1.4.0beta55 [April 15, 2009]

+  Revised libpng*.txt and libpng.3 to mention calling png_set_IHDR()
+    multiple times and to specify the sample order in the tRNS chunk,
+    because the ISO PNG specification has a typo in the tRNS table.
+  Changed several PNG_UNKNOWN_CHUNK_SUPPORTED to
+    PNG_HANDLE_AS_UNKNOWN_SUPPORTED, to make the png_set_keep mechanism
+    available for ignoring known chunks even when not saving unknown chunks.

+    "#if defined()" and "if !defined()" where possible.
+

+  Removed extraneous declaration from the new call to png_read_gray_to_rgb()
+    (bug introduced in libpng-1.4.0beta67).
+  Fixed up xcode project (Alam Arias)
+
+version 1.4.0beta70 [July 27, 2009]
+  Avoid a possible NULL dereference in debug build, in png_set_text_2().

+  Moved CMakeLists.txt from scripts into the main libpng directory.
+  Various bugfixes and improvements to CMakeLists.txt (Philip Lowman)

+version 1.4.0beta78 [August 31, 2009]
+  Converted all PNG_NO_* tests to PNG_*_SUPPORTED everywhere except pngconf.h
+  Eliminated PNG_NO_FREE_ME and PNG_FREE_ME_SUPPORTED macros.

+
+version 1.4.0beta86 [October 9, 2009]

+  Eliminated a shadowed declaration of "pp" in png_handle_sPLT().
+
+version 1.4.0rc01 [October 19, 2009]

+
+version 1.4.0beta87 [October 30, 2009]
+  Moved version 1.4.0 back into beta.
+
+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)

+    of differences from 1.2.41 to 1.4.0)
+
+version 1.4.0beta93 [November 7, 2009]
+  Added PNG_DEPSTRUCT, PNG_DEPRECATED, PNG_USE_RESULT, PNG_NORETURN, and
+    PNG_ALLOCATED macros to detect deprecated direct access to the
+    png_struct or info_struct members and other deprecated usage in
+    applications (John Bowler).
+  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
+    that they need to be updated, to remove references to pnggccrd.c and
+    pngvcrd.c and to depend on pngpriv.h
+  Removed three direct references to read_info_ptr members in pngtest.c
+    that were detected by the new PNG_DEPSTRUCT macro.

+    png_debug(), png_debug1(), and png_debug2() from libpng.3 to libpngpf.3.
+
+version 1.4.0beta94 [November 9, 2009]
+  Removed the obsolete, unused pnggccrd.c and pngvcrd.c files.
+  Updated CMakeLists.txt to add "-DPNG_CONFIGURE_LIBPNG" to the definitions.
+  Removed dependency of pngtest.o on pngpriv.h in the makefiles.
+  Only #define PNG_DEPSTRUCT, etc. in pngconf.h if not already defined.
+
+version 1.4.0beta95 [November 10, 2009]
+  Changed png_check_sig() to !png_sig_cmp() in contrib programs.
+  Added -DPNG_CONFIGURE_LIBPNG to contrib/pngminm/*/makefile

+  Renamed scripts/makefile.wce to scripts/makefile.cegcc
+  Revised Makefile.am to use libpng.sys while building libpng.so
+    so that only PNG_EXPORT functions are exported.
+  Removed the deprecated png_check_sig() function/macro.
+  Removed recently removed function names from scripts/*.def
+  Revised pngtest.png to put chunks in the same order written by pngtest
+    (evidently the same change made in libpng-1.0beta54 was lost).
+  Added PNG_PRIVATE macro definition in pngconf.h for possible future use.
+
+version 1.4.0beta97 [November 13, 2009]
+  Restored pngtest.png to the libpng-1.4.0beta7 version.
+  Removed projects/beos and netware.txt; no one seems to be supporting them.
+  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
+    modified Makefile.am and configure.ac accordingly.  Now "configure"
+    needs nothing from the "scripts" directory.
+
+version 1.4.0beta100 [November 14, 2009]
+  Removed ASM builds from projects/visualc6 and projects/visualc71
+  Removed scripts/makefile.nommx and makefile.vcawin32
+  Revised CMakeLists.txt to account for new location of libpng-config.in
+    and libpng-pc.in
+  Updated INSTALL to reflect removal and relocation of files.
+
+version 1.4.0beta101 [November 14, 2009]
+  Restored the binary files (*.jpg, *.png, some project files) that were
+    accidentally deleted from the zip and 7z distributions when the xcode
+    project was added.
+
+version 1.4.0beta102 [November 18, 2009]
+  Added libpng-config.in and libpng-pc.in to the zip and 7z distributions.
+  Fixed a typo in projects/visualc6/pngtest.dsp, introduced in beta100.
+  Moved descriptions of makefiles and other scripts out of INSTALL into
+    scripts/README.txt
+  Updated the copyright year in scripts/pngwin.rc from 2006 to 2009.
+
+version 1.4.0beta103 [November 21, 2009]
+  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 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.
+  Make the 'png_jmpbuf' macro expand to a call that records the correct
+    longjmp function as well as returning a pointer to the setjmp
+    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
+  Rebuilt configure scripts with autoconf-2.65
+
+version 1.4.0beta105 [November 25, 2009]
+  Use fast integer PNG_DIVIDE_BY_255() or PNG_DIVIDE_BY_65535()
+    to accomplish alpha premultiplication when
+    PNG_READ_COMPOSITE_NODIV_SUPPORTED is defined.
+  Changed "/255" to "/255.0" in background calculations to make it clear
+    that the 255 is used as a double.
+
+version 1.4.0beta106 [November 27, 2009]
+  Removed premultiplied alpha feature.
+
+version 1.4.0beta107 [December 4, 2009]
+  Updated README
+  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/libpng14 instead of in
+    $prefix/include/libpng/libpng14.
+
+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
+    (revising the change in 1.4.0beta99)
+
+version 1.4.0rc04 [December 25, 2009]
+  Swapped PNG_UNKNOWN_CHUNKS_SUPPORTED and PNG_HANDLE_AS_UNKNOWN_SUPPORTED
+    in pngset.c to be consistent with other changes in version 1.2.38.
+
+version 1.4.0rc05 [December 25, 2009]
+  Changed "libpng-pc.in" to "libpng.pc.in" in configure.ac, configure, and
+    Makefile.in to be consistent with changes in libpng-1.4.0rc03
+
+version 1.4.0rc06 [December 29, 2009]
+  Reverted the gamma_table changes from libpng-1.4.0beta109.
+  Fixed some indentation errors.
+
+version 1.4.0 [December 29, 2009]
