This directory contains sample repositories from different versions of Notary client (TUF metadata, trust anchor certificates, and private keys), in order to test backwards compatibility (that newer clients can read old-format repositories).

Notary client makes no guarantees of future-compatibility though (that is, repositories produced by newer clients may not be able to be read by old clients.)

Backwards compatibility has been tested in `client/backwards_compatibility_test.go`
