                What has changed in GDB?
             (Organized release by release)
 
-*** Changes since GDB 7.3.1
+*** Changes since GDB 7.4
+
+* Python scripting
+
+  ** The "maint set python print-stack on|off" is now deleted.
+
+  ** A new class, gdb.printing.FlagEnumerationPrinter, can be used to
+     apply "flag enum"-style pretty-printing to any enum.
+
+  ** gdb.lookup_symbol can now work when there is no current frame.
+
+  ** gdb.Symbol now has a 'line' attribute, holding the line number in
+     the source at which the symbol was defined.
+
+  ** gdb.Symbol now has the new attribute 'needs_frame' and the new
+     method 'value'.  The former indicates whether the symbol needs a
+     frame in order to compute its value, and the latter computes the
+     symbol's value.
+
+* GDBserver now supports stdio connections.
+  E.g. (gdb) target remote | ssh myhost gdbserver - hello
+
+* The binary "gdbtui" can no longer be built or installed.
+  Use "gdb -tui" instead.
+
+* GDB will now print "flag" enums specially.  A flag enum is one where
+  all the enumerator values have no bits in common when pairwise
+  "and"ed.  When printing a value whose type is a flag enum, GDB will
+  show all the constants, e.g., for enum E { ONE = 1, TWO = 2}:
+  (gdb) print (enum E) 3
+  $1 = (ONE | TWO)
+
+* The filename part of a linespec will now match trailing components
+  of a source file name.  For example, "break gcc/expr.c:1000" will
+  now set a breakpoint in build/gcc/expr.c, but not
+  build/libcpp/expr.c.
+
+* The "info proc" and "generate-core-file" commands will now also
+  work on remote targets connected to GDBserver on Linux.
+
+* The command "info catch" has been removed.  It has been disabled
+  since December 2007.
+
+* New commands
+
+  ** "catch load" and "catch unload" can be used to stop when a shared
+     library is loaded or unloaded, respectively.
+
+  ** "enable count" can be used to auto-disable a breakpoint after
+     several hits.
+
+* New targets

+
+*** Changes in GDB 7.4
+
+* GDB now handles ambiguous linespecs more consistently; the existing
+  FILE:LINE support has been expanded to other types of linespecs.  A
+  breakpoint will now be set on all matching locations in all
+  inferiors, and locations will be added or removed according to
+  inferior changes.
 
 * GDB now allows you to skip uninteresting functions and files when
   stepping with the "skip function" and "skip file" commands.
