» Overview

This page contains the list of breaking changes for Vault 0.6 compared to the previous release. Please read it carefully.

» PKI Backend Does Not Issue Leases for CA Certificates

When a token expires, it revokes all leases associated with it. This means that long-lived CA certs need correspondingly long-lived tokens, something that is easy to forget, resulting in an unintended revocation of the CA certificate when the token expires. To prevent this, root and intermediate CA certs no longer have associated leases. To revoke these certificates, use the pki/revoke endpoint.

CA certificates that have already been issued and acquired leases will report to the lease manager that revocation was successful, but will not actually be revoked and placed onto the CRL.

» The auth/token/revoke-prefix Endpoint Has Been Removed

As part of addressing a minor security issue, this endpoint has been removed in favor of using sys/revoke-prefix for prefix-based revocation of both tokens and secrets leases.

» Go API Uses json.Number For Decoding

When using the Go API, it now calls UseNumber() on the decoder object. As a result, rather than always decode as a float64, numbers are returned as a json.Number, where they can be converted, with proper error checking, to int64, float64, or simply used as a string value. This fixes some display errors where numbers were being decoded as float64 and printed in scientific notation.

» List Operations Return 404 On No Keys Found

Previously, list operations on an endpoint with no keys found would return an empty response object. Now, a 404 will be returned instead.

» Consul TTL Checks Automatically Registered

If using the Consul HA storage backend, Vault will now automatically register itself as the vault service and perform its own health checks/lifecycle status management. This behavior can be adjusted or turned off in Vault's configuration; see the documentation for details.
