Joey Hess e213ef310f git-annex (5.20140717) unstable; urgency=high
* Fix minor FD leak in journal code. Closes: #754608
  * direct: Fix handling of case where a work tree subdirectory cannot
    be written to due to permissions.
  * migrate: Avoid re-checksumming when migrating from hashE to hash backend.
  * uninit: Avoid failing final removal in some direct mode repositories
    due to file modes.
  * S3: Deal with AWS ACL configurations that do not allow creating or
    checking the location of a bucket, but only reading and writing content to
    it.
  * resolvemerge: New plumbing command that runs the automatic merge conflict
    resolver.
  * Deal with change in git 2.0 that made indirect mode merge conflict
    resolution leave behind old files.
  * sync: Fix git sync with local git remotes even when they don't have an
    annex.uuid set. (The assistant already did so.)
  * Set gcrypt-publish-participants when setting up a gcrypt repository,
    to avoid unncessary passphrase prompts.
    This is a security/usability tradeoff. To avoid exposing the gpg key
    ids who can decrypt the repository, users can unset
    gcrypt-publish-participants.
  * Install nautilus hooks even when ~/.local/share/nautilus/ does not yet
    exist, since it is not automatically created for Gnome 3 users.
  * Windows: Move .vbs files out of git\bin, to avoid that being in the
    PATH, which caused some weird breakage. (Thanks, divB)
  * Windows: Fix locking issue that prevented the webapp starting
    (since 5.20140707).

When generating a view, there's now a way to reuse part of the directory
hierarchy of the parent branch. For example, `git annex view tag=* podcasts/=*`
makes a view where the first level is the tags, and the second level is
whatever `podcasts/*` directories the files were in.
Also, year and month metadata can be automatically recorded when
adding files to the annex. I made this only be done when annex.genmetadata
is turned on, to avoid polluting repositories that don't want to use metadata.
It would be nice if there was a way to add a hook script that's run
when files are added, to collect their metadata. I am not sure yet if
I am going to add that to git-annex though. It's already possible to do via
the regular git `post-commit` hook. Just make it look at the commit to see
what files were added, and then run `git annex metadata` to set their
metadata appropriately. It would be good to at least have an example of
such a script to eg, extract EXIF or ID3 metadata. Perhaps someone can
contribute one?
