 * Other changes:
 
-  - Optimized strlen_P, thanks to Jan Waclawek. Rename strlen_P to be 
__strlen_P
-  and add new strlen_P inline function in header file that checks if value is a
-  constant and known at compile time. If not, then the new inline function 
calls
-  __strlen_P as normal.
+  - The old prog_* typedefs are now deprecated, and are only included
+  if requested by the user.  This request is expressed by declaring
+  the macro __PROG_TYPES_COMPAT__, either by a #define directive
+  before including <avr/pgmspace.h>, or by a -D compiler option.
