+*** Changes since GDB 7.6
+
+* Python scripting
+
+ ** Frame filters and frame decorators have been added.
+
+* New targets
+
+Nios II ELF nios2*-*-elf
+Nios II GNU/Linux nios2*-*-linux
+Texas Instruments MSP430 msp430*-*-elf
+
+* New commands:
+catch rethrow
+ Like "catch throw", but catches a re-thrown exception.
+maint check-psymtabs
+ Renamed from old "maint check-symtabs".
+maint check-symtabs
+ Perform consistency checks on symtabs.
+maint expand-symtabs
+ Expand symtabs matching an optional regexp.
+
+show configuration
+ Display the details of GDB configure-time options.
+
+maint set|show per-command
+maint set|show per-command space
+maint set|show per-command time
+maint set|show per-command symtab
+ Enable display of per-command gdb resource usage.
+
+* New options
+
+set print raw frame-arguments
+show print raw frame-arguments
+ Set/show whether to print frame arguments in raw mode,
+ disregarding any defined pretty-printers.
+
+set remote trace-status-packet
+show remote trace-status-packet
+ Set/show the use of remote protocol qTStatus packet.
+
+set debug nios2
+show debug nios2
+ Control display of debugging messages related to Nios II targets.
+
+set range-stepping
+show range-stepping
+ Control whether target-assisted range stepping is enabled.
+
+* You can now use a literal value 'unlimited' for options that
+ interpret 0 or -1 as meaning "unlimited". E.g., "set
+ trace-buffer-size unlimited" is now an alias for "set
+ trace-buffer-size -1" and "set height unlimited" is now an alias for
+ "set height 0".
+
+* New command-line options
+--configuration
+ Display the details of GDB configure-time options.
+
+* The command 'tsave' can now support new option '-ctf' to save trace
+ buffer in Common Trace Format.
+
+* Newly installed $prefix/bin/gcore acts as a shell interface for the
+ GDB command gcore.
+
+* GDB now implements the the C++ 'typeid' operator.
+
+* The new convenience variable $_exception holds the exception being
+ thrown or caught at an exception-related catchpoint.
+
+* The exception-related catchpoints, like "catch throw", now accept a
+ regular expression which can be used to filter exceptions by type.
+
+* MI changes
+
+ ** The -trace-save MI command can optionally save trace buffer in Common
+ Trace Format now.
+
+ ** The new command -dprintf-insert sets a dynamic printf breakpoint.
+
+ ** The command -data-list-register-values now accepts an optional
+ "--skip-unavailable" option. When used, only the available registers
+ are displayed.
+
+ ** The new command -trace-frame-collected dumps collected variables,
+ computed expressions, tvars, memory and registers in a traceframe.
+
+* New system-wide configuration scripts
+ A GDB installation now provides scripts suitable for use as system-wide
+ configuration scripts for the following systems:
+ ** ElinOS
+ ** Wind River Linux
+
+* GDB now supports target-assigned range stepping with remote targets.
+ This improves the performance of stepping source lines by reducing
+ the number of control packets from/to GDB. See "New remote packets"
+ below.
+
+* GDB now understands the element 'tvar' in the XML traceframe info.
+ It has the id of the collected trace state variables.
+
+* New remote packets
+
+vCont;r
+
+ The vCont packet supports a new 'r' action, that tells the remote
+ stub to step through an address range itself, without GDB
+ involvemement at each single-step.
+
+qXfer:libraries-svr4:read's annex
+ The previously unused annex of the qXfer:libraries-svr4:read packet
+ is now used to support passing an argument list. The remote stub
+ reports support for this argument list to GDB's qSupported query.
+ The defined arguments are "start" and "prev", used to reduce work
+ necessary for library list updating, resulting in significant
+ speedup.
+
+* New features in the GDB remote stub, GDBserver
+
+ ** GDBserver now supports target-assisted range stepping. Currently
+ enabled on x86/x86_64 GNU/Linux targets.
+
+ ** GDBserver now adds element 'tvar' in the XML in the reply to
+ 'qXfer:traceframe-info:read'. It has the id of the collected
+ trace state variables.
+
+ ** GDBserver now supports hardware watchpoints on the MIPS GNU/Linux
+ target.
+
+* New 'z' formatter for printing and examining memory, this displays the
+ value as hexadecimal zero padded on the left to the size of the type.
+
+*** Changes in GDB 7.6
+
+* Target record has been renamed to record-full.
+ Record/replay is now enabled with the "record full" command.
+ This also affects settings that are associated with full record/replay
+ that have been moved from "set/show record" to "set/show record full":
+
+set|show record full insn-number-max
+set|show record full stop-at-limit
+set|show record full memory-query
+
+* A new record target "record-btrace" has been added. The new target
+ uses hardware support to record the control-flow of a process. It
+ does not support replaying the execution, but it implements the
+ below new commands for investigating the recorded execution log.
+ This new recording method can be enabled using:
+
+record btrace
+
+ The "record-btrace" target is only available on Intel Atom processors
+ and requires a Linux kernel 2.6.32 or later.
+
+* Two new commands have been added for record/replay to give information
+ about the recorded execution without having to replay the execution.
+ The commands are only supported by "record btrace".
+
+record instruction-history prints the execution history at
+ instruction granularity
+
+record function-call-history prints the execution history at
+ function granularity
+
+* New native configurations
