 Changes since the last public release (1.2.42):
 
-version 1.2.43 [February 25, 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
+
+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
