    remote packets have been defined to support static tracepoints, see
    the "New remote packets" section below.
  
+ * Better reconstruction of tracepoints after disconnected tracing
+ 
+   GDB will attempt to download the original source form of tracepoint
+   definitions when starting a trace run, and then will upload these
+   upon reconnection to the target, resulting in a more accurate
+   reconstruction of the tracepoints that are in use on the target.
+ 
+ * Observer mode
+ 
+   You can now exercise direct control over the ways that GDB can
+   affect your program.  For instance, you can disallow the setting of
+   breakpoints, so that the program can run continuously (assuming
+   non-stop mode).  In addition, the "observer" variable is available
+   to switch all of the different controls; in observer mode, GDB
+   cannot affect the target's behavior at all, which is useful for
+   tasks like diagnosing live systems in the field.
+ 
+ * The new convenience variable $_thread holds the number of the
+   current thread.

  * The source command now accepts a -s option to force searching for the

    a directory.
