 *** Changes since GDB 7.7
+ 
+* The ARM simulator now supports instruction level tracing
+  with or without disassembly.
+
+* Guile scripting
+
+  GDB now has support for scripting using Guile.  Whether this is
+  available is determined at configure time.
+  Guile version 2.0 or greater is required.
+  Guile version 2.0.9 is well tested, earlier 2.0 versions are not.
+
+* New commands (for set/show, see "New options" below)
+
+guile [code]
+gu [code]
+  Invoke CODE by passing it to the Guile interpreter.
+
+guile-repl
+gr
+  Start a Guile interactive prompt (or "repl" for "read-eval-print loop").
+
+info auto-load guile-scripts [regexp]
+  Print the list of automatically loaded Guile scripts.
+
+* The source command is now capable of sourcing Guile scripts.
+  This feature is dependent on the debugger being built with Guile support.
+
+* New options
+
+set print symbol-loading (off|brief|full)
+show print symbol-loading
+  Control whether to print informational messages when loading symbol
+  information for a file.  The default is "full", but when debugging
+  programs with large numbers of shared libraries the amount of output
+  becomes less useful.
+
+set guile print-stack (none|message|full)
+show guile print-stack
+  Show a stack trace when an error is encountered in a Guile script.
+
+set auto-load guile-scripts (on|off)
+show auto-load guile-scripts
+  Control auto-loading of Guile script files.
+
+maint ada set ignore-descriptive-types (on|off)
+maint ada show ignore-descriptive-types
+  Control whether the debugger should ignore descriptive types in Ada
+  programs.  The default is not to ignore the descriptive types.  See
+  the user manual for more details on descriptive types and the intended
+  usage of this option.
+
+* New features in the GDB remote stub, GDBserver
+
+  ** New option --debug-format=option1[,option2,...] allows one to add
+     additional text to each output.  At present only timestamps
+     are supported: --debug-format=timestamps.
+     Timestamps can also be turned on with the
+     "monitor set debug-format timestamps" command from GDB.
+
+* The 'record instruction-history' command now starts counting instructions
+  at one.  This also affects the instruction ranges reported by the
+  'record function-call-history' command when given the /i modifier.
+
+* The command 'record function-call-history' supports a new modifier '/c' to
+  indent the function names based on their call stack depth.
+  The fields for the '/i' and '/l' modifier have been reordered.
+  The source line range is now prefixed with 'at'.
+  The instruction range is now prefixed with 'inst'.
+  Both ranges are now printed as '<from>, <to>' to allow copy&paste to the
+  "record instruction-history" and "list" commands.
+
+* The ranges given as arguments to the 'record function-call-history' and
+  'record instruction-history' commands are now inclusive.
+
+* The btrace record target now supports the 'record goto' command.
+  For locations inside the execution trace, the back trace is computed
+  based on the information stored in the execution trace.
+
+* The btrace record target supports limited reverse execution and replay.
+  The target does not record data and therefore does not allow reading
+  memory or registers.
+
+* The "catch syscall" command now works on s390*-linux* targets.
+
+* New remote packets
+
+qXfer:btrace:read's annex
+  The qXfer:btrace:read packet supports a new annex 'delta' to read
+  branch trace incrementally.
+
+* Python Scripting
+
+  ** Valid Python operations on gdb.Value objects representing
+     structs/classes invoke the corresponding overloaded operators if
+     available.
+
+* New targets
+PowerPC64 GNU/Linux little-endian	powerpc64le-*-linux*
+
+* The "dll-symbols" command, and its two aliases ("add-shared-symbol-files"
+  and "assf"), have been deprecated.  Use the "sharedlibrary" command, or
+  its alias "share", instead.
 
 *** Changes in GDB 7.7
 
+* Improved support for process record-replay and reverse debugging on
+  arm*-linux* targets.  Support for thumb32 and syscall instruction
+  recording has been added.
+
 * GDB now supports SystemTap SDT probes on AArch64 GNU/Linux.
 
 * GDB now supports Fission DWP file format version 2.
