I was puzzled, believing that recent versions used v6 repository format.

Indeed, all my repositories have been created with 6.20161011-g3135d35 with default options (indirect mode).

```
git-annex version: 6.20161011-g3135d35

```

I understand now that v6 is still experimental and not enabled by default ( ref http://git-annex.branchable.com/devblog/day_421__lost_in_the_trees/ ).
