*** Changes since GDB 7.4
+* The "info os" command on GNU/Linux can now display information on
+ several new classes of objects managed by the operating system:
+ "info os procgroups" lists process groups
+ "info os files" lists file descriptors
+ "info os sockets" lists internet-domain sockets
+ "info os shm" lists shared-memory regions
+ "info os semaphores" lists semaphores
+ "info os msg" lists message queues
+ "info os modules" lists loaded kernel modules
+
* GDB now has support for SDT (Static Defined Tracing) probes. Currently,
the only implemented backend is for SystemTap probes (<sys/sdt.h>). You
can set a breakpoint using the new "-probe, "-pstap" or "-probe-stap"
