NEWS:
        Changes

        - 'mtn clone' now takes a branch argument rather than a branch
          option which is more what people expect given the fact that
          mtn push/pull/sync do not use a branch option either.

        - 'mtn automate inventory' will show the birth revision for
          any file that has been committed.

        Bugs fixed

        - If the options '--db' or '--keydir' were previously
          specified for a command which was executed inside a
          workspace and one or both option arguments were invalid
          (f.e. invalid paths), they were still written to
          _MTN/options of the particular workspace.  This lead to
          errors on any subsequent command which used these
          options. This bug is fixed in so far that basic file type
          checks are applied on both options, so its no longer
          possible to set non-existing paths accidentally or use a
          path to a directory as option argument for '--db'.

        - If a key clash occurs on a netsync operation, i.e. two
          different keys with the same key id are encountered, mtn now
          fails cleanly and provides further guidance how to proceed.

        - It was previously not possible to clone a branch / database
          anonymously; this has been fixed.

        - If the client tries to use an unknown key, try to fall back
          to anonymous pull instead of failing immediately.

        - 'mtn automate identify' was broken in 0.40 when used over
          stdio, i.e. the output of the command did not get into the
          right output channel; this has been fixed.

        - Monotone would produce a warning if executed from the root
          directory of a Windows drive; this has been fixed.

        - The 'note_commit' hook now returns the new revision id
          hex-encoded again - the bug was introduced in 0.40.

        New features

        - New 'mtn suspend' command which lets you mark certain
          revisions and thus whole branches as discontinued
          ("suspended") by attaching a special suspend cert to the
          revision. All relevant mtn commands (f.e. mtn heads,
          mtn ls branches) honor this cert by default. To ignore it,
          simply add '--ignore-suspend-certs' to your command line.
          Suspended revisions can have children, which are in no
          way affected by the cert of their parent, i.e. suspended
          development lines or branches can simply be "unsuspended"
          by committing to them.
          This feature was already added in monotone 0.37, but was
          forgotten to be mentioned in NEWS back then.

        - New 'get_default_command_options' lua hook which lets you
          specify default options for a given, triggered command.
          Useful f.e. if you always want to have your 'mtn add'
          command executed with '-R' / '--recursive'.

        - Add 'automate show_conflicts' command.

        - Add 'automate get_workspace_root' command.

        - Add Lua hooks 'note_netsync_revision_sent',
          'note_netsync_cert_sent' and 'note_netsync_pubkey_sent'.
