 Changes since the last public release (1.2.36):
 
-version 1.2.37 [June 4, 2009]
-
+version 1.2.37beta01 [May 14, 2009]
   Fixed inconsistency in pngrutil.c, introduced in libpng-1.2.36.  The
     memset() was using "png_ptr->rowbytes" instead of "row_bytes", which
     the corresponding png_malloc() uses (Joe Drew).
   Clarified usage of sig_bit versus sig_bit_p in example.c (Vincent Torri)
-  Updated some of the makefiles in the scripts directory.
+  Updated some of the makefiles in the scripts directory (merged with
+    those in libpng-1.4.0beta57).
+
+version 1.2.37beta02 [May 19, 2009]
   Fixed typo in libpng documentation (FILTER_AVE should be FILTER_AVG)
   Relocated misplaced #endif in pngwrite.c, sCAL chunk handler.
   Conditionally compile png_read_finish_row() which is not used by
     progressive readers.
   Added contrib/pngminim/preader to demonstrate building minimal progressive
     decoder, based on contrib/gregbook with embedded libpng and zlib.
+
+version 1.2.37beta03 [May 20, 2009]
   In contrib/pngminim/*, renamed "makefile.std" to "makefile", since there
     is only one makefile in those directories, and revised the README files
     accordingly.
   Reformated sources in libpng style (3-space indentation, comment format)
+
+version 1.2.37rc01 [May 27, 2009]
+  No changes.
+
+versions 1.2.37 and 1.0.45 [June 4, 2009]
+  Reformatted several remaining "else statement;" and "if () statment;" into
+    two lines.
+  Added "#define PNG_NO_WRITE_SWAP" to contrib/pngminim/encoder/pngusr.h
+    and "define PNG_NO_READ_SWAP" to decoder/pngusr.h and preader/pngusr.h
   Added sections about the git repository and our coding style to the
     documentation (merged from libpng-1.4.0beta62)
   Added a section about using png_get_io_ptr() in configure scripts to detect
     the presence of libpng.
