 		What has changed since GDB-3.5?
+		(Organized release by release)
 
+*** Changes in GDB-4.1:
+
+ *  Multiple source language support
+
+GDB now has internal scaffolding to handle several source languages.
+It determines the type of each source file from its filename extension,
+and will switch expression parsing and number formatting to match the
+language of the function in the currently selected stack frame.
+You can also specifically set the language to be used, with
+`set language c' or `set language modula-2'.
 
  *  GDB and Modula-2

 Other Modula-2 compilers are currently not supported, and attempting to
 debug programs compiled with them will likely result in an error as the
-symbol table of the executable is read in.
+symbol table is read.  Feel free to work on it, though!
+
+There are hooks in GDB for strict type checking and range checking,
+in the `Modula-2 philosophy', but they do not currently work.
+
+ * set write on/off
+
+GDB can now write to executable and core files (e.g. patch
+a variable's value).   You must turn this switch on, specify
+the file ("exec foo" or "core foo"), *then* modify it, e.g.
+by assigning a new value to a variable.  Modifications take
+effect immediately.
+
+ * Automatic SunOS shared library reading
+
+When you run your program, GDB automatically determines where its
+shared libraries (if any) have been loaded, and reads their symbols.
+The `share' command is no longer needed.  This also works when
+examining core files.
+
+ * set listsize
+
+You can specify the number of lines that the `list' command shows.
+The default is 10.
+
+ * New machines supported (host and target)

+SGI Iris (MIPS) running Irix V3:  	mips-sgi-irix   or  iris
