Joey Hess 7189dfd77d git-annex (5.20131127) unstable; urgency=low
* webapp: Detect when upgrades are available, and upgrade if the user
    desires.
    (Only when git-annex is installed using the prebuilt binaries
    from git-annex upstream, not from eg Debian.)
  * assistant: Detect when the git-annex binary is modified or replaced,
    and either prompt the user to restart the program, or automatically
    restart it.
  * annex.autoupgrade configures both the above upgrade behaviors.
  * Added support for quvi 0.9. Slightly suboptimal due to limitations in its
    interface compared with the old version.
  * Bug fix: annex.version did not get set on automatic upgrade to v5 direct
    mode repo, so the upgrade was performed repeatedly, slowing commands down.
  * webapp: Fix bug that broke switching between local repositories
    that use the new guarded direct mode.
  * Android: Fix stripping of the git-annex binary.
  * Android: Make terminal app show git-annex version number.
  * Android: Re-enable XMPP support.
  * reinject: Allow to be used in direct mode.
  * Futher improvements to git repo repair. Has now been tested in tens
    of thousands of intentionally damaged repos, and successfully
    repaired them all.
  * Allow use of --unused in bare repository.

Worked on making the assistant able to merge in existing encrypted
git repositories from rsync.net.
This had two parts. First, making the webapp UI where you click to enable a
known special remote work with these encrypted repos. Secondly, handling
the case where a user knows they have an encrypted repository on rsync.net,
so enters in its hostname and path, but git-annex doesn't know about that
special remote. The second case is important, for example, when the
encrypted repository is a backup and you're restoring from it. It wouldn't
do for the assistant, in that case, to make a *new* encrypted repo and
push it over top of your backup!
Handling that was a neat trick. It has to do quite a lot of probing, including
downloading the whole encrypted git repo so it can decrypt it and merge it,
to find out about the special remote configuration used for it. This all
works with just 2 ssh connections, and only 1 ssh password prompt max.
Next, on to generalizing this rsync.net specific code to work with
arbitrary ssh servers!
