   Removed makefile.mingw.
   Eliminated PNG_NO_EXTERN and PNG_ALL_EXTERN
 
-version 1.5.0beta16 [March 17, 2010]
+version 1.5.0beta16 [March 30, 2010]
+  Make png_text_struct independent of PNG_iTXt_SUPPORTED, so that
+    fields are initialized in all configurations.  The READ/WRITE
+    macros (PNG_(READ|WRITE)_iTXt_SUPPORTED) still function as
+    before to disable code to actually read or write iTXt chunks
+    and iTXt_SUPPORTED can be used to detect presence of either
+    read or write support (but it is probably better to check for
+    the one actually required - read or write.)
