+
+  On FreeBSD, git-annex incorrectly calculated SHA256 hashes for files
+  added to the annex repository due to the BSD-style output of
+  /sbin/sha256.  The result of this is silent data corruption.
+
+  This problem has been fixed, but every file stored in an annex
+  repository will fail a `git annex fsck` after the upgrade.  Thus,
+  before updating, it is wise to issue the command below and restore the
+  files.
+
+  $ git annex uninit
+
+  Corruptions can then be found by finding all files with the same hash.
+  Note that only files that were mishashed to the same location are a
+  problem.
