 *** Changes since GDB 7.4
 
+* GDB now supports debugging microMIPS binaries.
+
+* 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"

   ** A new method 'referenced_value' on gdb.Value objects which can
      dereference pointer as well as C++ reference values.
 
+  ** New methods 'global_block' and 'static_block' on gdb.Symtab objects
+     which return the global and static blocks (as gdb.Block objects),
+     of the underlying symbol table, respectively.
+
+  ** New function gdb.find_pc_line which returns the gdb.Symtab_and_line
+     object associated with a PC value.

 * Go language support.
   GDB now supports debugging programs written in the Go programming
   language.

+     is basically a breakpoint that does a printf and immediately
+     resumes your program's execution, so it is like a printf that you
+     can insert dynamically at runtime instead of at compiletime.

+     Controls whether GDB attempts to display the symbol, if any,
+     corresponding to addresses it prints.  This defaults to "on", but
+     you can set it to "off" to restore GDB's previous behavior.
