(Organized release by release)
*** Changes since GDB 7.9
+=======
+
+* GDB now honors the content of the file /proc/PID/coredump_filter
+ (PID is the process ID) on GNU/Linux systems. This file can be used
+ to specify the types of memory mappings that will be included in a
+ corefile. For more information, please refer to the manual page of
+ "core(5)". GDB also has a new command: "set use-coredump-filter
+ on|off". It allows to set whether GDB will read the content of the
+ /proc/PID/coredump_filter file when generating a corefile.
+
+* The "info os" command on GNU/Linux can now display information on
+ cpu information :
+ "info os cpus" Listing of all cpus/cores on the system
+
+* GDB has two new commands: "set serial parity odd|even|none" and
+ "show serial parity". These allows to set or show parity for the
+ remote serial I/O.
+
+* The "info source" command now displays the producer string if it was
+ present in the debug info. This typically includes the compiler version
+ and may include things like its command line arguments.
+
+* Directory names supplied to the "set sysroot" commands may be
+ prefixed with "target:" to tell GDB to access shared libraries from
+ the target system, be it local or remote. This replaces the prefix
+ "remote:". The default sysroot has been changed from "" to
+ "target:". "remote:" is automatically converted to "target:" for
+ backward compatibility.
+
+* Python Scripting
+
+ ** gdb.Objfile objects have a new attribute "username",
+ which is the name of the objfile as specified by the user,
+ without, for example, resolving symlinks.
+ ** You can now write frame unwinders in Python.
+
+* New commands
+
+maint print symbol-cache
+ Print the contents of the symbol cache.
+
+maint print symbol-cache-statistics
+ Print statistics of symbol cache usage.
+
+maint flush-symbol-cache
+ Flush the contents of the symbol cache.
+
+record btrace bts
+record bts
+ Start branch trace recording using Branch Trace Store (BTS) format.
+
+* New options
+
+set max-completions
+show max-completions
+ Set the maximum number of candidates to be considered during
+ completion. The default value is 200. This limit allows GDB
+ to avoid generating large completion lists, the computation of
+ which can cause the debugger to become temporarily unresponsive.
+
+maint set symbol-cache-size
+maint show symbol-cache-size
+ Control the size of the symbol cache.
+
+set|show record btrace bts buffer-size
+ Set and show the size of the ring buffer used for branch tracing in
+ BTS format.
+ The obtained size may differ from the requested size. Use "info
+ record" to see the obtained buffer size.
+
+* The command 'thread apply all' can now support new option '-ascending'
+ to call its specified command for all threads in ascending order.
+
+* Python/Guile scripting
+
+ ** GDB now supports auto-loading of Python/Guile scripts contained in the
+ special section named `.debug_gdb_scripts'.
+
+* New remote packets
+
+qXfer:btrace-conf:read
+ Return the branch trace configuration for the current thread.
+
+Qbtrace-conf:bts:size
+ Set the requested ring buffer size for branch tracing in BTS format.
+
+swbreak stop reason
+ Indicates a memory breakpoint instruction was executed, irrespective
+ of whether it was GDB that planted the breakpoint or the breakpoint
+ is hardcoded in the program. This is required for correct non-stop
+ mode operation.
+
+hwbreak stop reason
+ Indicates the target stopped for a hardware breakpoint. This is
+ required for correct non-stop mode operation.
+
+vFile:fstat:
+ Return information about files on the remote system.
+
+* The info record command now shows the recording format and the
+ branch tracing configuration for the current thread when using
+ the btrace record target.
+ For the BTS format, it shows the ring buffer size.
+
+* GDB now has support for DTrace USDT (Userland Static Defined
+ Tracing) probes. The supported targets are x86_64-*-linux-gnu.
+
+* GDB now supports access to vector registers on S/390 GNU/Linux
+ targets.
+
+* Removed targets and native configurations
+
+HP/PA running HP-UX hppa*-*-hpux*
+Itanium running HP-UX ia64-*-hpux*
