-Changes since the last public release (1.0.50):
+Changes since the last public release (1.2.42):
 
-version 1.2.41beta01 [September 25, 2009]
-  Moved redundant IHDR checking into new png_check_IHDR() in png.c
-    and report all errors found in the IHDR data.
-  Eliminated useless call to png_check_cHRM() from pngset.c
-  Expanded TAB characters in pngrtran.c
+version 1.2.43beta01 [January 27, 2010]
+  Updated CMakeLists.txt for consistent indentation and to avoid an
+    unclosed if-statement warning (Philip Lowman).
+  Removed "#ifdef PNG_1_0_X / #endif" surrounding
+    PNG_READ_16_TO_8_SUPPORTED and PNG_READ_GRAY_TO_RGB_SUPPORTED
+    in pngconf.h.  These were added in libpng-1.2.41beta08 and libpng-1.0.51,
+    which introduced a binary incompatibility with libpng-1.0.50.
+  Backported new png_decompress_chunk() algorithm from libpng-1.4.1
 
-version 1.2.41beta02 [September 30, 2009]
-  Revised png_check_IHDR().
+version 1.2.43beta02 [February 1, 2010]
+  Backported two-pass png_decompress_chunk() algorithm from libpng-1.4.1
 
-version 1.2.41beta03 [October 1, 2009]
-  Revised png_check_IHDR() again, to check info_ptr members instead of
-    the contents of the returned parameters.
+version 1.2.43beta03 [February 6, 2010]
+  Backported fast png_push_save_buffer() algorithm from libpng-1.4.1
 
-version 1.2.41beta04 [October 7, 2009]
-  Added "xcode" project similar one already in libpng-1.4.0beta (Alam Arias).
-  Ported some cosmetic changes from libpng-1.4.0beta86.
-  Eliminated a shadowed declaration of "pp" in png_handle_sPLT().
+version 1.2.43beta04 [February 8, 2010]
+  Reverted recent changes to png_push_save-buffer().
+  Removed PNGAPI declaration of png_calloc() and png_write_sig() in
+    1ibpng-1.2.X, introduced by mistake in libpng-1.2.41.
+  Return allocated "old_buffer" in png_push_save_buffer() before png_error(),
+    to avoid a potential memory leak.
 
-version 1.2.41beta05 [October 17, 2009]
-  Revised pngconf.h to make it easier to enable iTXt support.  From libpng
-    version 1.2.9 through 1.2.40, defining PNG_iTXt_SUPPORTED did not work
-    as expected.
-  Ported some cosmetic changes from libpng-1.4.0beta87, changing
-    many "#if defined(x)" to "#ifdef x".
+version 1.2.43beta05 [February 8, 2010]
+  Ported rewritten png_decompress_chunk() by John Bowler from libpng-1.4.1.
 
-version 1.2.41beta06 [October 18, 2009]
-  Restored PNG_USE_LOCAL_ARRAYS code in pngread.c that was inadvertently
-    deleted in libpng-1.2.41beta05.
-  Converted all PNG_NO_* tests to PNG_*_SUPPORTED everywhere except pngconf.h
-    as in libpng-1.4.0beta78 and later.
+version 1.0.53rc01 and 1.2.43rc01 [February 20, 2010]
+  No changes.
 
-version 1.2.41beta07 [October 21, 2009]
-  Ported some cosmetic changes from libpng-1.4.0rc01, changing
-    many "#if defined(x)" to "#ifdef x" in png.h and pngconf.h.
-
-version 1.2.41beta08 [October 30, 2009]
-  Ported from libpng-1.4.0rc01: png_calloc(), png_get_io_chunk_name(),
-    png_get_io_state(), png_set_user_cache_max(), png_get_user_cache_max(),
-    png_set_premultiply_alpha, and png_do_read_premultiply_alpha().
-  Relocated png_do_chop() ahead of building gamma tables in pngrtran.c
-    This avoids building 16-bit gamma tables unnecessarily.
-
-version 1.2.41beta09 [November 1, 2009]
-  Removed a harmless extra png_set_invert_alpha() from pngwrite.c
-  More bugfixes and improvements to CMakeLists.txt (Philip Lowman)
-  Moved CMakeLists.txt from scripts into the main libpng directory.
-  Apply png_user_chunk_cache_max within png_decompress_chunk().
-  Merged libpng-1.2.41.txt with libpng-1.4.0.txt where appropriate.
-
-version 1.2.41beta10 [November 1, 2009]
-  Enabled iTXt support by default. To ensure binary compatibility with
-    previous versions, the "lang" and "lang_key" members will be assumed
-    to be omitted from previous versions unless the current libpng
-    version was built with PNG_iTXt_SUPPORTED (which is otherwise no
-    longer necessary to gain iTXt support), as a signal that the user has
-    been building previous versions with PNG_iTXt_SUPPORTED as well.
-
-version 1.2.41beta11 [November 2, 2009]
-  Store user's user_png_ver in new png_ptr->user_png_ver element.
-  Revised iTXt support. To ensure binary compatibility with
-    previous versions, the "lang" and "lang_key" members will be assumed
-    to be omitted from versions prior to 1.2.41beta11 whenever there is a
-    library mismatch.
-
-version 1.2.41beta12 [November 2, 2009]
-  Free png_ptr->user_png_ver when destroying png_ptr.
-
-version 1.2.41beta13 [November 3, 2009]
-  Updated scripts/pngw32.def and projects/wince/png32ce.def
-  Copied projects/wince/png32ce.def to the scripts directory.
-  Added scripts/makefile.wce
-  Patched ltmain.sh for wince support.
-  Added PNG_CONVERT_tIME_SUPPORTED macro.
-
-version 1.2.41beta14 [November 8, 2009]
-  versions 1.2.41beta05 through 1.2.41beta13 were abandoned.
-  Make inclusion of time.h in pngconf.h depend on PNG_CONVERT_tIME_SUPPORTED
-  Make #define PNG_CONVERT_tIME_SUPPORTED depend on PNG_WRITE_tIME_SUPPORTED
-  Reverted iTXt compatibility stuff from 1.2.41beta05, 1.2.41beta11, and
-    1.2.41beta12.
-  Reverted IOSTATE feature, user_cache_max, and premultiply_alpha features
-    from 1.2.41beta08.
-  Retained png_calloc() from 1.2.41beta08 but as a non-exported function,
-    and removed reference to png_calloc from scripts/*.def
-
-version 1.2.41beta15 [November 8, 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".
-
-version 1.2.41beta16 [November 9, 2009]
-  Removed three direct references to read_info_ptr members in pngtest.c
-    that were detected by the new PNG_DEPSTRUCT macro.
-  Only #define PNG_DEPSTRUCT, etc. in pngconf.h if not already defined.
-
-version 1.2.41beta17 [November 10, 2009]
-  Updated CMakeLists.txt to add "-DPNG_CONFIGURE_LIBPNG" to the definitions.
-  Marked deprecated function prototypes with PNG_DEPRECATED.
-  Marked memory allocation function prototypes with PNG_ALLOCATED.
-  Changed png_check_sig() to !png_sig_cmp() in contrib programs.
-  Corrected the png_get_IHDR() call in contrib/gregbook/readpng2.c
-  Added "-DPNG_CONFIGURE_LIBPNG" to the contrib/pngminum makefiles.
-
-version 1.2.41beta18 [November 11, 2009]
-  Renamed scripts/makefile.wce to scripts/makefile.cegcc
-  Marked nonexported functions with PNG_PRIVATE macro.
-
-version 1.2.41beta18 [November 11, 2009]
-  Revised scripts/*.def to reflect functions actually exported by libpng.
-
-version 1.2.41rc01 and 1.0.51rc01 [November 18, 2009]
-  Revised scripts/*.def to reflect functions actually exported by libpng.
-  Updated the copyright year in scripts/pngw32.rc from 2004 to 2009.
-  Moved descriptions of makefiles and other scripts out of INSTALL into
-    scripts/README.txt
+version 1.0.53rc02 and 1.2.43rc02 [February 20, 2010]
+  Define _ALL_SOURCE in pngconf.h when building with AIX compiler.

    Y2K compliance in libpng:
    =========================
 
-      November 18, 2009
+      February 20, 2010
 
       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 1.0.51rc01 are Y2K compliant.  It is my belief that earlier
+      upward through 1.2.43rc02 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
