   * info: Don't allow use in a non-git-annex repository, since it
     uses the git-annex branch and would create it if it were missing.
-  * S3: Added support for storageclass=STANDARD_IA to use Amazon's
-    new Infrequently Accessed storage.
-    (Needs aws-0.13.0.)
-  * S3: Use aws-0.13.0, which allows using storageclass=NEARLINE
+  * S3: When built with aws-0.13.0, supports using more storage classes.
+    In particular, storageclass=STANDARD_IA to use Amazon's

     to use Google's NearLine storage.
