Joey Hess 341269e035 git-annex (4.20130815) unstable; urgency=low
* assistant, watcher: .gitignore files and other git ignores are now
    honored, when git 1.8.4 or newer is installed.
    (Thanks, Adam Spiers, for getting the necessary support into git for this.)
  * importfeed: Ignores transient problems with feeds. Only exits nonzero
    when a feed has repeatedly had a problems for at least 1 day.
  * importfeed: Fix handling of dots in extensions.
  * Windows: Added support for encrypted special remotes.
  * Windows: Fixed permissions problem that prevented removing files
    from directory special remote. Directory special remotes now fully usable.
