Update monotone to 0.46.  Tested under OS X 10.5 and NetBSD/macppc.

Sun Jan 17 21:40:35 UTC 2010

        0.46 release.

        Changes

        - "automate stdio" (and "automate remote_stdio", see \ 
below)
          use separate streams to encode out-of-band information like
          informational messages, warnings or tickers. A special
          "header" section has been added to the standard output to
          identify future stdio version changes. The error codes used
          in the output of both stdio and remote_stdio, have also
          slightly changed: errors which are the result of a wrong
          call (unknown command, invalid options, parsing errors, ...)
          are returned with code 1, while errors which happened while
          the actual command executed are returned with code 2. Error
          codes are no longer echoed with every packet, but only as
          the payload of the final 'l' ("last") packet.

          Please consult the manual section "mtn automate stdio" for a
          detailed description of the new format.

        - The 'heads' command should be significantly faster now (not
          that it was particularly slow before). This probably isn't
          terribly noticable unless you're in the habit of using "h:*"
          (heads of all branches) as a selector, it's primarily meant
          to enable future changes that will depend on fast 'heads'.

          The database schema has been changed, so you will need to
          run 'mtn db migrate' (preferably after making a backup copy
          of your db).

        - the 'status' command now includes the current (to be committed)
          revision number and will indicate when the branch option in
          _MTN/options has been changed and does not match one of the
          revision's parent branches.

        - Cert labels in the output of the 'log' command are now
          localized.

        New features

        - There's a new command "automate remote_stdio" that makes it
          possible to execute automate commands on a remote server
          (for example, to permit a single database to be used both
          for serving netsync connections and for running a viewmtn
          instance). This requires that the server be running monotone
          0.46 or later. Access control on the server uses a new lua
          hook "get_remote_automate_permitted(identity, command_line,
          options)".

        - There's also a new command "automate remote" that's very much
          the same, but executes only a single command and does not
          stdio-encode the output.

        - A new 'bisect' command has been added to allow searching for a
          specific revision within a range of revisions. This can be useful for
          locating the exact revision that broke something or removed a
          particular feature.

        - Three new commands - 'push', 'pull' and 'sync' - have been added
          to the automation interface. They work just as their non-automate
          counterparts.

        - The global option '--timestamps' has been added which prefixes
          the current local timestamp before diagnostic messages such as
          warnings, progress messages, errors and tickers.  For example,
          this option can be used to log the date and time when clients
          connect to a monotone server.

        Bugs fixed

        - A regression from 0.45's key migration prevented the proper
          output of the `committer` field in 'git_export'.

        - 'db info --full' no longer crashes when executed on a database
          with only one revision.

        - The mtn_automate Lua function which can be used for custom
          commands now properly handles binary data.

        - `db info` now returns a correct byte count for certs again.

        - If a public key was read in via the `read` or
          `automate read_packets`, an invariant was triggered if the
          key was already existing in the database. This has been fixed.

        - `annotate` no longer crashes if the annotated file is empty.

        Other

        - Added the script of the Lua-based contributed Monotone
          extension command "mtn remote_export" to contrib/command/
          with which a remote revision can be exported locally without
          having to fetch all of the history before.
