+maint show target-async
+  This controls whether GDB targets operate in syncronous or
+  asyncronous mode.  Normally the default is asyncronous, if it is
+  available; but this can be changed to more easily debug problems
+  occurring only in syncronous mode.
+
+set mi-async (on|off)
+show mi-async
+  Control whether MI asynchronous mode is preferred.  This supersedes
+  "set target-async" of previous GDB versions.
+
+* "set target-async" is deprecated as a CLI option and is now an alias
+  for "set mi-async" (only puts MI into async mode).
+
+* Background execution commands (e.g., "c&", "s&", etc.) are now
+  possible ``out of the box'' if the target supports them.  Previously
+  the user would need to explicitly enable the possibility with the
+  "set target-async on" command.

 * The "catch syscall" command now works on s390*-linux* targets.
 
+* The "compare-sections" command is no longer specific to target
+  remote.  It now works with all targets.
+
+* All native targets are now consistently called "native".
+  Consequently, the "target child", "target GNU", "target djgpp",
+  "target procfs" (Solaris/Irix/OSF/AIX) and "target darwin-child"
+  commands have been replaced with "target native".  The QNX/NTO port
+  leaves the "procfs" target in place and adds a "native" target for
+  consistency with other ports.  The impact on users should be minimal
+  as these commands previously either throwed an error, or were
+  no-ops.  The target's name is visible in the output of the following
+  commands: "help target", "info target", "info files", "maint print
+  target-stack".
+
+* The "target native" command now connects to the native target.  This
+  can be used to launch native programs even when "set
+  auto-connect-native-target" is set to off.
