        Changes

        - mtn db kill_rev_locally now checks for an existing workspace
          before the revision is killed and tries to apply the changes
          of this particular revision back to the workspace to allow
          easy re-committing afterwards

        - the "--brief" switch for mtn annotate has been renamed to
          "--revs-only" for clarity

        - mtn help now lists the commands (and their aliases) available
          within a group, so its easier to get an overview which commands
          are available at all

        - the "MTN_MERGE=diffutils" merger (provided by std_hooks.lua)
          was improved. It now accepts a MTN_MERGE_DIFFUTILS environment
          variable which can be used to control its behaviour
          through comma-separated "key[=value]" entries. Currently
          supported entries are "partial" for doing a partial
          batch/non-modal 3-way merge conflict "resolution" which uses
          embedded content conflict markers and "diff3opts=[...]" and
          "sdiffopts=[...]" for passing arbitrary options to the used
          "diff3" and "sdiff" tools. When used in \ 
combination with "mtn
          merge_into_workspace" this way one especially can achieve a
          CVS/SVN style non-modal workspace-based merging.

        - There is a new revision selector: "p:REV" selects the
          parent(s) of revision REV.  For example, if a revision has
          one parent,

             mtn diff -r p:REV -r REV

          will show the changes made in that revision.

        - Monotone now uses the Perl-Compatible Regular Expression
          (PCRE) library for all regular expressions, instead of the
          boost::regex library.  This means that external Boost
          libraries are no longer required to build or use Monotone.
          If building from source, you will still need the Boost headers
          available somewhere.  See INSTALL for details.

          PCRE's syntax for regular expressions is a superset of
          boost::regex's syntax; it is unlikely that any existing
          .mtn-ignore files or other user uses of regexps will break.
          The manual now contains detailed documentation of the regexp
          syntax, borrowed from PCRE itself.

        - the format of "mtn automate inventory" has changed to basic_io.
          This fixes a couple of corner cases where the old format
          returned wrong information and introduces new capabilities like
          restricted output, recognized attribute changes, and more.
          For a complete overview on the new format, please take a look
          in the appropriate manual section.

        Bugs fixed

        - mtn automate heads called without a branch argument now properly
          returns the head revisions of the workspace's branch if called
          over mtn automate stdio

        - mtn commit no longer crashes if it creates a revision whose
          roster already exists, i.e. was left behind by the command
          `mtn db kill_rev_locally REV` (savannah #18990)

        Documentation changes

        - the documentation of the "--revs-only" (formerly \ 
"--brief")
          switch for the annotate command didn't match its actual
          behavior, this has been fixed

        - documentation for the "ssh_agent_add" command was missing
          and has been added

        Other

        - contrib/usher.cc has been removed. Please use the
          net.venge.monotone.contrib.usher branch instead.

        Internal

        - Update SQLite to 3.4.1.

        - Update Lua to 5.1.2 plus latest bug fixes.

        - Update Botan to 1.5.10.

        - Internal use of regular expressions has been almost eliminated.
          (Regular expressions are still used for .mtn-ignore and the
          --show-encloser feature of mtn diff, and are still available to
          Lua hooks.)
