doc: west: add v0.6.1 documentation

West v0.6.1 has been released. The main feature is that "west update"
now avoids communicating with the network by default when project
revisions have already been fetched.

This allows for offline operation and significantly speeds up the
command (it's 10 times faster on my machine and home network).

There are other miscellaneous changes as well; document them also.

 West Release Notes
 ##################
 
-v0.6.x
+v0.6.1
+******
+
+The user-visible features in this point release are:
+
+- The `west update <west-multi-repo-cmds>` command has a new ``--fetch``
+  command line flag and ``update.fetch`` :ref:`configuration option
+  <west-config>`. The default value, "smart", skips fetching SHAs and tags
+  which are available locally.
+- Better and more consistent error-handling in the ``west diff``, ``west
+  status``, ``west forall``, and ``west update`` commands. Each of these
+  commands can operate on multiple projects; if a subprocess related to one
+  project fails, these commands now continue to operate on the rest of the
+  projects. All of them also now report a nonzero error code from the west
+  process if any of these subprocesses fails (this was previously not true of
+  ``west forall`` in particular).
+- The :ref:`west manifest <west-multi-repo-misc>` command also handles errors
+  better.
+- The :ref:`west list <west-multi-repo-misc>` command now works even when the
+  projects are not cloned, as long as its format string only requires
+  information which can be read from the manifest file. It still fails if the
+  format string requires data stored in the project repository, e.g. if it
+  includes the ``{sha}`` format string key.
+- Commands and options which operate on git revisions now accept abbreviated
+  SHAs. For example, ``west init --mr SHA_PREFIX`` now works. Previously, the
+  ``--mr`` argument needed to be the entire 40 character SHA if it wasn't a
+  branch or a tag.
+
+The developer-visible changes to the :ref:`west-apis` are:
+
+- west.log.banner(): new
+- west.log.small_banner(): new
+- west.manifest.Manifest.get_projects(): new
+- west.manifest.Project.is_cloned(): new
+- west.commands.WestCommand instances can now access the parsed
+  Manifest object via a new self.manifest property during the
+  do_run() call. If read, it returns the Manifest object or
+  aborts the command if it could not be parsed.
+- west.manifest.Project.git() now has a capture_stderr kwarg
