- git-annex (5.20151117) UNRELEASED; urgency=medium
++
 +  * annex.version increased to 6, but version 5 is also still supported.
 +  * The upgrade to version 6 is not done fully automatically, because
 +    upgrading a direct mode repository to version 6 will prevent old
 +    versions of git-annex from working in other clones of that repository.
 +  * smudge: New command, used for git smudge filter. 
 +    This will replace direct mode.
 +  * init: Configure .git/info/attributes to use git-annex as a smudge
 +    filter. Note that this changes the default behavior of git add in a
 +    newly initialized repository; it will add files to the annex.
 +
+ git-annex (5.20151208) unstable; urgency=medium
  
    * Build with -j1 again to get reproducible build.
    * Display progress meter in -J mode when copying from a local git repo,
