IN DEVELOPMENT

--------------

  COMPATIBILITY BREAKS:

    * ``exporters/bzr-fast-export`` has been replaced with a

      ``fast-export`` command. Some minor issues have been

      fixed at the same time: the first commit now goes into

      refs/heads/master (not refs/head/tmp); there's no

      checkpoint at the top of the stream; parent commits are

      now always given lower mark numbers than the commits they

      are merged into. (Ian Clatworthy)

    * The ``fast-import`` command now uses a different mapping of

      git reference names to bzr branch names. In summary:

      * ``refs/heads/foo`` is mapped to ``foo``

      * ``refs/remotes/origin/foo`` is mapped to ``foo.remote``

      * ``refs/tags/foo`` is mapped to ``foo.tag``

      * ``*/master`` is mapped to ``trunk``, ``trunk.remote``, etc.

      * ``*/trunk`` is mapped to ``git-trunk``, ``git-trunk.remote``, etc.

      This new mapping has been introduced so that more natural

      branch names are used and to enable round-tripping back to git.

      (Ian Clatworthy)

    * The old ``fast-import-filter`` command is now called

      ``fast-import-query``. ``fast-import-filter`` now

      really filters the input to produce a fast-import stream

      based on filtering criteria. See below.

      (Ian Clatworthy)

    * The ``--inv-fulltext`` option is no longer supported. It was

      only used in experimental mode for old versions of bzrlib so

      it added more complexity than value. (Ian Clatworthy)

  FEATURES:

    * Added ``fast-import-filter`` command for splitting out a

      subdirectory or bunch of files into their own project. It can

      also be used to create a new repository without any history

      for nominated files and directories. This is useful for

      removing information which is a security risk, huge binary

      files like ISO images, etc.

      (Ian Clatworthy)

    * Copying of files and symbolic links is now supported.

      (Ian Clatworthy)

    * Initial cut at reset support. (Brian de Alwis, Ian Clatworthy)

  IMPROVEMENTS:

    * If ``refs/heads/xxx`` and ``refs/remotes/origin/xxx`` are both

      defined, the latter is now mapped to a bzr branch called

      ``xxx.remote`` rather than ``remotes--origins--xxx``.

      (Ian Clatworthy)

    * ``bzr fast-import-info`` now handles an unlimited # of parents for a

      revision. The spec suggests the maximum ought to be 16 but the linux

      kernel has revisions with more than that.

      (Ian Clatworthy)

    * ``bzr fast-import-info`` now reports on things that may need caching,

      i.e. merges, rename old paths and copy source paths.

      (Ian Clatworthy)

    * Tag commands with a missing from clause now produce a warning but

      are otherwise ignored. (Scott James Remnant, Ian Clatworthy)

    * The fastimport-id-map file can now have more revisions than the

      repository. (Scott James Remnant)

    * Updated the bundled version of hg-fast-export to be the latest

      code from http://repo.or.cz/w/fast-export.git. It should now

      support recent Mercurial releases.

      (Ian Clatworthy, #318903)

  BUG FIXES:

    * Fixed a *bad* bug where filecopy commands were being parsed

      as filerename commands. Repositories generated by previous

      version of bzr-fast-import where the input stream contained

      filecopy commands might be missing data (the copy source will

      no longer be there if it was unchanged since the copy happened)

      and ought to be regenerated.

      (Ian Clatworthy)

    * Fixed how the per-file graph is generated. The per-file graph

      may still be less than perfect in the case where a file is only

      changed in a merge and not the parent, but in the vast majority

      of cases now, ``bzr check`` should no longer report inconsistent

      parents. (Ian Clatworthy)

    * Fix ``os`` import as needed on Windows.

      (Ian Clatworthy, esskov, #264988)

    * Handle a directory turning into a file and then the children

      of that directory being deleted.

      (Ian Clatworthy, #309486)

    * Handle an empty email section.

      (Ian Clatworthy)

    * Handle multiple merges within the one merge clause. That's illegal

      according to the spec but git-fast-export does it.

      (Ian Clatworthy, #259711)

    * Handle names and paths that aren't utf8 encoded. The spec recommends

      utf8 encoding of these but git-fast-export doesn't always do that.

      (Ian Clatworthy, #289088)

    * Ignore lightweight tags with no from clause rather than abort.

      (It seems git-fast-export outputs these commands frequently now

      while it didn't appear to in early versions.)

      (Ian Clatworthy, edice, #259711)

    * Import into rich-root (and subtree) repositories without aborting.

      (Ian Clatworthy, #300921)

    * Recursively delete children when a directory is deleted.

      (Scott James Remnant)

    * The ``deleteall`` command now only tries to delete files in the

      nominated branch, not all known files. As a consequence,

      it should now be possible (if it wasn't before) to import

      multiple Darcs branches (via darcs-fast-export) at once.

      (Ian Clatworthy)

  API BREAKS:

  TESTING:

    * A large number of tests have been added.

      (Ian Clatworthy)

  INTERNALS:

    * Refactored ``processors/generic_processor.py`` into a bunch of modules.

      (Ian Clatworthy)

0.7 09-Feb-2009

---------------

  COMPATIBILITY BREAKS:

    * bzr-fast-export.py renamed to bzr-fast-export.

      (Jelmer Vernooij)

  IMPROVEMENTS:

    * Add support for the deleteall command.

      (Miklos Vajna, #284941)

  BUG FIXES:

    * bzr-fast-export now exports rm+mv correctly.

      (Jonas)

    * Fix recursive rename handling in bzr-fast-export.

      (Pieter de Bie, #287785)

    * hg-fast-export should use binary mode on Windows.

      (Alexey Stukalov)

    * setup.py no longer assumes python2.4.

      (schickb@gmail.com)

    * setup.py support fixed.

      (Jelmer Vernooij)

    * Update the last-modified revision for a renamed file.

      (John Arbash Meinel)

0.6 23-Jul-2008

---------------

  FEATURES:

  IMPROVEMENTS:

    * Added NEWS containing Release Notes. (Ian Clatworthy)

    * ``bzr help fastimport`` now provides help that is useful.

      (Ian Clatworthy)

    * Numerous fixes to ``bzr-fast-export.py`` to improve round-tripping

      with Git. Added ``--import-marks`` and ``--export-marks`` options

      to ``fast-import`` as well.

      (Pieter de Bie)

    * ``svn-fast-export.py`` now supports a regular-expression to specify

      the branches to export.

      (Mirko Friedenhagen)

  BUG FIXES:

    * Support the new Repository API added in bzr.dev r3510. The old API

      will be used for earlier versions of bzr including bzr 1.6beta2 and

      earlier. (Ian Clatworthy)

  COMPATIBILITY BREAKS:

    * The ``--inv-fulltext`` option is not yet supported when the new

      Repository API is used to import revisions. The option can be

      provided but it will be ignored. (Ian Clatworthy)

  API BREAKS:

    * The ``RevisionLoader`` class has been renamed to ``RevisionLoader1``.

      The ``ExperimentalRevisionLoader`` class has been renamed to

      ``ImportRevisionLoader1``. New classes called ``RevisionLoader2``

      and ``ImportRevisionLoader2`` are provided that use the new

      Repository API. (Ian Clatworthy)

  TESTING:

  INTERNALS:

    * Improved packaging by adding a setup.py file. (Ian Clatworthy)

0.5 02-Jun-2008

---------------

  FEATURES:

    * Version suitable for Bazaar 1.5.

      (Ian Clatworthy)
