Please read it carefully. ### Convergent Encryption version 3 If you are using `transit`'s convergent encryption feature, which prior to this release was at version 2, we recommend [rotating](/api/secret/transit#rotate-key) your encryption key (the new key will use version 3) and [rewrapping](/api/secret/transit#rewrap-data) your data to mitigate the chance of offline plaintext-confirmation attacks. ### PKI duration return types The PKI backend now returns durations (e.g. when reading a role) as an integer number of seconds instead of a Go-style string.
