 Changes since the last public release (1.2.46):
 
-version 1.2.47beta01 [February 17, 2012]
-  Updated contrib/pngminus/makefile.std (Samuli Souminen)
 
-version 1.2.47rc01 [February 17, 2012]
-  Fixed CVE-2011-3026 buffer overrun bug.
+version 1.2.48beta01 [Febuary 27, 2012]
+  Removed two useless #ifdef directives from pngread.c and one from pngrutil.c
+  Eliminated redundant png_push_read_tEXt|zTXt|iTXt|unknown code from
+    pngpread.c and use the sequential png_handle_tEXt, etc., in pngrutil.c;
+    now that png_ptr->buffer is inaccessible to applications, the special
+    handling is no longer useful.
+  Fixed bug with png_handle_hIST with odd chunk length (Frank Busse).
+  Fixed incorrect type (int copy should be png_size_t copy) in png_inflate().
+  Fixed off-by-one bug in png_handle_sCAL() when using fixed point arithmetic,
+    causing out-of-bounds read in png_set_sCAL() because of failure to copy
+    the string terminators (Franke Busse).
+
+version 1.2.48rc01 [March 2, 2012]
+  Removed the png_free() of unused png_ptr->current_text from pngread.c.
+  Added libpng license text to pnggccrd.c and pngvcrd.c (requested by Chrome).
