 # Minimal printf and snprintf
 
 
-Library supports both printf and snprintf in 1252 bytes of flash.
+Library supports both printf and snprintf in around 1300 bytes of flash.
 
 Prints directly to stdio/UART without using malloc. All flags and precision modifiers are ignored.
 There is no error handling if a writing error occurs.
