*** Changes since GDB 8.0
-* On Unix systems, GDBserver now does globbing expansion and variable
- substitution in inferior command line arguments.
-
- This is done by starting inferiors using a shell, like GDB does.
- See "set startup-with-shell" in the user manual for how to disable
- this from GDB when using "target extended-remote". When using
- "target remote", you can disable the startup with shell by using the
- new "--no-startup-with-shell" GDBserver command line option.
+* New features in the GDB remote stub, GDBserver
+
+ ** New "--selftest" command line option runs some GDBserver self
+ tests. These self tests are disabled in releases.
