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.
+
* New remote packets
qGetTIBAddr
tracepoint action). The remote stub reports support for this packet
to gdb's qSupported query.
+QAllow
+
+ Send the current settings of GDB's permission flags.
+
+QTDPsrc
+
+ Send part of the source (textual) form of a tracepoint definition,
+ which includes location, conditional, and action list.
+
* The source command now accepts a -s option to force searching for the
script in the source search path even if the script name specifies
a directory.
Define a static tracepoint by probing a marker at the given
function, line, address, or marker ID.

+ Set individual permissions for GDB effects on the target. Note that
+ some of these settings can have undesirable or surprising
+ consequences, particularly when changed in the middle of a session.
+ For instance, disabling the writing of memory can prevent
+ breakpoints from being inserted, cause single-stepping to fail, or
+ even crash your program, if you disable after breakpoints have been
+ inserted. However, GDB should not crash.
