 *** Changes since GDB 6.8
 
+* GDB now has an interface for JIT compilation.  Applications that
+dynamically generate code can create symbol files in memory and register
+them with GDB.  For users, the feature should work transparently, and
+for JIT developers, the interface is documented in the GDB manual in the
+"JIT Compilation Interface" chapter.
+
 * Tracepoints may now be conditional.  The syntax is as for
 breakpoints; either an "if" clause appended to the "trace" command,
 or the "condition" command is available.  GDB sends the condition to

+* Target descriptions can now describe "compatible" architectures
+to indicate that the target can execute applications for a different
+architecture in addition to those for the main target architecture.
+See the "Target Description Format" section in the user manual for
+more information.
+
+* Multi-architecture debugging.
+
+  GDB now includes general supports for debugging applications on
+  hybrid systems that use more than one single processor architecture
+  at the same time.  Each such hybrid architecture still requires
+  specific support to be added.  The only hybrid architecture supported
+  in this version of GDB is the Cell Broadband Engine.
+
+* GDB now supports integrated debugging of Cell/B.E. applications that
+use both the PPU and SPU architectures.  To enable support for hybrid
+Cell/B.E. debugging, you need to configure GDB to support both the
+powerpc-linux or powerpc64-linux and the spu-elf targets, using the
+--enable-targets configure option.
