+*** Changes since GDB 5.2:
+
+* Changes in FreeBSD/i386 native debugging.
+
+Support for the "generate-core-file" has been added.
+
+* New commands "dump", "append", and "restore".
+
+These commands allow data to be copied from target memory
+to a bfd-format or binary file (dump and append), and back
+from a file into memory (restore).
+
+*** Changes in GDB 5.2:
+
+* New command "set trust-readonly-sections on[off]".
+
+This command is a hint that tells gdb that read-only sections
+really are read-only (ie. that their contents will not change).
+In this mode, gdb will go to the object file rather than the
+target to read memory from read-only sections (such as ".text").
+This can be a significant performance improvement on some
+(notably embedded) targets.
+
+* New command "generate-core-file" (or "gcore").
+
+This new gdb command allows the user to drop a core file of the child
+process state at any time.  So far it's been implemented only for
+GNU/Linux and Solaris, but should be relatively easily ported to other
+hosts.  Argument is core file name (defaults to core.<pid>).
 
 * New command line option
