Current Storage Formats

:pack-0.92:
    (native) (default) New in 0.92: Pack-based format with data
    compatible with dirstate-tags format repositories. Interoperates
    with bzr repositories before 0.92 but cannot be read by bzr <
    0.92. Previously called knitpack-experimental.  For more
    information, see http://doc.bazaar-
    vcs.org/latest/developers/packrepo.html.

:rich-root-pack:
    (native) New in 1.0: A variant of pack-0.92 that supports rich-
    root data (needed for bzr-svn).

:1.6:
    (native) A format that allows a branch to indicate that there is
    another (stacked) repository that should be used to access data
    that is not present locally.

:1.6.1-rich-root:
    (native) A variant of 1.6 that supports rich-root data (needed for
    bzr-svn).

:1.9:
    (native) A repository format using B+tree indexes. These indexes
    are smaller in size, have smarter caching and provide faster
    performance for most operations.

:1.9-rich-root:
    (native) A variant of 1.9 that supports rich-root data (needed for
    bzr-svn).
