*** Changes since GDB 11
+* Configure changes
+
+--enable-threading
+
+ Enable or disable multithreaded symbol loading. This is enabled
+ by default, but passing --disable-threading or --enable-threading=no
+ to configure will disable it.
+
+ Disabling this can cause a performance penalty when there are a lot of
+ symbols to load, but is useful for debugging purposes.
+
* New commands
maint set backtrace-on-fatal-signal on|off
These are now deprecated aliases for "set max-value-size" and
"show max-value-size".
+task apply [all | TASK-IDS...] [FLAG]... COMMAND
+ Like "thread apply", but applies COMMAND to Ada tasks.
+
+watch [...] task ID
+ Watchpoints can now be restricted to a specific Ada task.
+
maint set internal-error backtrace on|off
maint show internal-error backtrace
maint set internal-warning backtrace on|off
internal-error, or an internal-warning. This is on by default for
internal-error and off by default for internal-warning.
+set logging on|off
+ Deprecated and replaced by "set logging enabled on|off".
+
+set logging enabled on|off
+show logging enabled
+ These commands set or show whether logging is enabled or disabled.
+
+exit
+ You can now exit GDB by using the new command "exit", in addition to
+ the existing "quit" command.
+
+set debug threads on|off
+show debug threads
+ Print additional debug messages about thread creation and deletion.
+
+set debug linux-nat on|off
+show debug linux-nat
+ These new commands replaced the old 'set debug lin-lwp' and 'show
+ debug lin-lwp' respectively. Turning this setting on prints debug
+ messages relating to GDB's handling of native Linux inferiors.
+
+maint flush source-cache
+ Flush the contents of the source code cache.
+
+maint set gnu-source-highlight enabled on|off
+maint show gnu-source-highlight enabled
+ Whether GDB should use the GNU Source Highlight library for adding
+ styling to source code. When off, the library will not be used, even
+ when available. When GNU Source Highlight isn't used, or can't add
+ styling to a particular source file, then the Python Pygments
+ library will be used instead.
+
+* Changed commands
+
+maint packet
+ This command can now print a reply, if the reply includes
+ non-printable characters. Any non-printable characters are printed
+ as escaped hex, e.g. \x?? where '??' is replaces with the value of
+ the non-printable character.
+
+clone-inferior
+ The clone-inferior command now ensures that the TTY, CMD and ARGS
+ settings are copied from the original inferior to the new one.
+ All modifications to the environment variables done using the 'set
+ environment' or 'unset environment' commands are also copied to the new
+ inferior.
+
+set debug lin-lwp on|off
+show debug lin-lwp
+ These commands have been removed from GDB. The new command 'set
+ debug linux-nat' and 'show debug linux-nat' should be used
+ instead.
+
* Python API
** New function gdb.add_history(), which takes a gdb.Value object
event is triggered once GDB decides it is going to exit, but
before GDB starts to clean up its internal state.
+ ** New function gdb.architecture_names(), which returns a list
+ containing all of the possible Architecture.name() values. Each
+ entry is a string.
+
+ ** New function gdb.Architecture.integer_type(), which returns an
+ integer type given a size and a signed-ness.
+
+ ** New gdb.TargetConnection object type that represents a connection
+ (as displayed by the 'info connections' command). A sub-class,
+ gdb.RemoteTargetConnection, is used to represent 'remote' and
+ 'extended-remote' connections.
+
+ ** The gdb.Inferior type now has a 'connection' property which is an
+ instance of gdb.TargetConnection, the connection used by this
+ inferior. This can be None if the inferior has no connection.
+
+ ** New 'gdb.events.connection_removed' event registry, which emits a
+ 'gdb.ConnectionEvent' when a connection is removed from GDB.
+ This event has a 'connection' property, a gdb.TargetConnection
+ object for the connection being removed.
+
+ ** New gdb.connections() function that returns a list of all
+ currently active connections.
+
+ ** New gdb.RemoteTargetConnection.send_packet(PACKET) method. This
+ is equivalent to the existing 'maint packet' CLI command; it
+ allows a user specified packet to be sent to the remote target.
+
+ ** New function gdb.host_charset(), returns a string, which is the
+ name of the current host charset.
+
+* New features in the GDB remote stub, GDBserver
+
+ ** GDBserver is now supported on OpenRISC GNU/Linux.
+
+* New native configurations
+
+GNU/Linux/OpenRISC or1k*-*-linux*
+
*** Changes in GDB 11
* The 'set disassembler-options' command now supports specifying options
