-version 1.0.54 [July 2, 2010]
+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
 
-  Rewrote png_process_IDAT_data to consistently treat extra data as warnings
-    and handle end conditions more cleanly.
+version 1.2.43beta02 [February 1, 2010]
+  Backported two-pass png_decompress_chunk() algorithm from libpng-1.4.1
+
+version 1.2.43beta03 [February 6, 2010]
+  Backported fast png_push_save_buffer() algorithm from libpng-1.4.1
+
+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 1.2.43beta05 [February 8, 2010]
+  Ported rewritten png_decompress_chunk() by John Bowler from libpng-1.4.1.
+
+version 1.0.53rc01 and 1.2.43rc01 [February 18, 2010]
+  No changes.
+
+version 1.0.53rc02 and 1.2.43rc02 [February 19, 2010]
+  Define _ALL_SOURCE in configure.ac, makefile.aix, and CMakeLists.txt
+    when using AIX compiler.
+
+version 1.0.53 and 1.2.43 [February 25, 2010]
+  Removed unused gzio.c from contrib/pngminim gather and makefile scripts
+
+version 1.2.44beta01 [June 18, 2010]
+  In pngpread.c: png_push_have_row() add check for new_row > height
   Removed the now-redundant check for out-of-bounds new_row from example.c
 
+version 1.2.44beta02 [June 19, 2010]
+  In pngpread.c: png_push_process_row() add check for too many rows.
+  Removed the now-redundant check for new_row > height in png_push_have_row().
 
+version 1.2.44beta03 [June 20, 2010]
+  Rewrote png_process_IDAT_data to consistently treat extra data as warnings
+    and handle end conditions more cleanly.
+  Removed the new (beta02) check in png_push_process_row().
+
+version 1.2.44rc01 [June 21, 2010]
+  Revised some comments in png_process_IDAT_data().
 Send comments/corrections/commendations to png-mng-implement at lists.sf.net
 
+version 1.2.44rc02 [June 22, 2010]
+  Stop memory leak when reading a malformed sCAL chunk.
+
+version 1.2.44rc03 [June 23, 2010]
+  Revised pngpread.c patch of beta05 to avoid an endless loop.
+

+  Pass "" instead of '\0' to png_default_error() in png_err().  This mistake
+    was introduced in libpng-1.2.20beta01.
+  Check for up->location !PNG_AFTER_IDAT when writing unknown chunks
+    before IDAT.
+  Ported bugfix in pngrtran.c from 1.5.3: when expanding a paletted image,
+    always expand to RGBA if transparency is present.
+
+version 1.2.45beta02 [June 8, 2011]
+  Check for integer overflow in png_set_rgb_to_gray().
+
+version 1.2.45beta03 [June 19, 2011]
+  Check for sCAL chunk too short.
