    15.1
      changes and enhancements:
	* Building GDB and GDBserver now requires a C++17 compiler (for instance,
	  GCC 9 or later).
	* Enhanced Python support
	  ** New function gdb.notify_mi(NAME, DATA), that emits custom
	     GDB/MI async notification.
	  ** New read/write attribute gdb.Value.bytes that contains a bytes
	     object holding the contents of this value.
	  ** New module gdb.missing_debug that facilitates dealing with
	     objfiles that are missing any debug information.
	  ** New function gdb.missing_debug.register_handler that can register
	     an instance of a sub-class of gdb.missing_debug.MissingDebugInfo
	     as a handler for objfiles that are missing debug information.
	  ** New class gdb.missing_debug.MissingDebugInfo which can be
	     sub-classed to create handlers for objfiles with missing debug
	     information.
	  ** Stop events now have a "details" attribute that holds a
	     dictionary that carries the same information as an MI "*stopped"
	     event.
	  ** New function gdb.interrupt(), that interrupts GDB as if the user
	     typed control-c.
	  ** New gdb.InferiorThread.ptid_string attribute.  This read-only
	     attribute contains the string that appears in the 'Target Id'
	     column of the 'info threads' command output.
	  ** It is no longer possible to create new gdb.Progspace object using
	     'gdb.Progspace()', this will result in a TypeError.  Progspace
	     objects can still be obtained through calling other API
	     functions, for example 'gdb.current_progspace()'.
	  ** User defined attributes can be added to a gdb.Inferior object,
	     these will be stored in the object's new Inferior.__dict__
	     attribute.
	  ** User defined attributes can be added to a gdb.InferiorThread
	     object, these will be stored in the object's new
	     InferiorThread.__dict__ attribute.
	  ** New constants gdb.SYMBOL_TYPE_DOMAIN, gdb.SYMBOL_FUNCTION_DOMAIN,
	     and gdb.SEARCH_*_DOMAIN
	* Debugger Adapter Protocol changes
	  ** GDB now emits the "process" event.
	  ** GDB now supports the "cancel" request.
	  ** The "attach" request now supports specifying the program.
	  ** New command "set debug dap-log-level" controls DAP logging.
	* Remote protocol
	  ** New stop reason: clone
	  ** QThreadOptions in qSupported
	  ** New remote packets: QThreadOptions, qIsAddressTagged
	  ** New "set/show remote thread-options-packet" commands
	* GDBserver
	  ** The --remote-debug and --event-loop-debug command line options
	     have been removed.
	  ** The --debug command line option now takes an optional comma
	     separated list of components to emit debug for.  The currently
	     supported components are: all, threads, event-loop, and remote.
	     If no components are given then threads is assumed.
	  ** The 'monitor set remote-debug' and 'monitor set event-loop-debug'
	     command have been removed.
	  ** The 'monitor set debug 0|1' command has been extended to take a
	     component name, e.g.: 'monitor set debug COMPONENT off|on'.
	     Possible component names are: all, threads, event-loop, and
	     remote.
	* Deprecated or removed
	  ** The MPX commands "show/set mpx bound" have been deprecated, as Intel
	     listed MPX as removed in 2019.
	* Miscellaneous
	  ** Guile API: New constants SYMBOL_TYPE_DOMAIN, SYMBOL_FUNCTION_DOMAIN,
	     and SEARCH_*_DOMAIN
	  ** New "set/show direct-call-timeout" commands.
	  ** New "set/show indirect-call-timeout" commands.
	  ** New "set/show unwind-on-timeout on|off" commands.
	  ** New "set/show unwind-on-signal on|off" commands, renaming the old
	     "set/show unwindonsignal" commands. The old commands are maintained
	     as an alias.
	  ** The "gcore" and "generate-core-file" commands now generates sparse
	     core files, on systems that support it.
	  ** The "maintenance info line-table" command now includes a new
	     EPILOGUE-BEGIN column indicating the start of the function's epilogue.
	  ** Simultaneous use of the 'r' and 'b' flags in the "disassemble" command
	     now triggers an error.
