-## Issues
-
-* There is no completion for commands - the default completion instead tries to
-  complete file names which is not very useful most of the time.
-* Decompilation is not implemented. The `ICSharpCode.Decompiler` library needs
-  to be separated from ILSpy for this to be practical.
-* The exit code of inferior processes is not shown. There is apparently no way
-  to get it from `Mono.Debugging`.
-* Attach support is not implemented. This requires special support in the
-  debugging libraries.
-* Some Mono versions throw a `NullReferenceException` when SDB shuts down. This
-  is because of a bug in the finalizer of `System.Timers.Timer` in Mono. This
-  bug has been fixed and should be available in whatever Mono version comes
-  after 3.2.5.
