  (Ale Gadea, Ganesh Sittampalam)
- darcs dist --zip: generate a zip archive from a repository
  (Guillaume Hoffmann)
- patch bundle contexts are minimized by default.
  Enables bundles to be applied to more repositories. (Guillaume Hoffmann)
- darcs convert export/import for conversion
  to/from VCSes supporting the fast-export protocol (Petr Rockai,
  Owen Stephens, Guillaume Hoffmann, Lele Gaifax, Ben Franksen)

  (Ganesh Sittampalam)

## User Interface ##

- add a last question after all patches have been selected to confirm
  the whole selection (Florent Becker)
- command names:
    - clone is the new name of get and put
    - log   is the new name of changes
    - amend is the new name of amend-record
- show output of log into a pager by default (Guillaume Hoffmann)
- the output of log is more similar to git's:
    - show patch hash in UI (hash of the patch's metadata)
    - put author and date on separate lines (Guillaume Hoffmann)
- enable to match on patch hash prefix with -h and --hash
 (Guillaume Hoffmann, Gian Piero Carrubba)

    - better error messages for http and ssh errors (Ernesto Rodriguez)
    - init, add, remove, move and replace print
      confirmation messages (Guillaume Hoffmann)

- darcs send no longer tries to send a mail by default (Eric Kow)
- when no patch name given, directly invoke text editor (Jose Neder,
Guillaume Hoffmann)

- keep log files for patch name and mail content in _darcs (Ale Gadea)
- optimize and convert are now supercommands (Guillaume Hoffmann)
- improve darcs help environment and darcs help markdown (Radoslav
Dorcik, Guillaume Hoffmann)
- warn about duplicate tags when creating a new one (Ale Gadea)
- allow darcs mv into known, but deleted in working, file (Owen Stephens)
- improve --not-in-remote, allowing multiple repos and use default
(Owen Stephens)

## Performance ##

  Benedikt Schmidt, Eric Kow, Guillaume Hoffmann, Ganesh Sittampalam)
