   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.
