+git-annex is not yet formally released. If you [[download]] it from git,
+everything described on this web site should already work, and I hope work
+well, with these exceptions:
+
+* The SHA1 backend is incomplete.
+
+I reserve the right to change its data formats before the first release,
+though I already have enough drives using it that I'd probably have to
+write a transition tool anyway!
