Log Message:
## 0.11.2 (October 2nd, 2018)

CHANGES:

- `sys/seal-status` now includes an `initialized` boolean in the
  output. If Vault is not initialized, it will return a `200` with
  this value set `false` instead of a `400`.
- `passthrough_request_headers` will now deny certain headers from
  being provided to backends based on a global denylist.

FEATURES:

- AWS Secret Engine Root Credential Rotation: The credential used by
  the AWS secret engine can now be rotated, to ensure that only Vault
  knows the credentials it is using.
- Storage Backend Migrator: A new `operator migrate` command allows
  offline migration of data between two storage backends.
- AliCloud KMS Auto Unseal and Seal Wrap Support (Enterprise):
  AliCloud KMS can now be used a support seal for  Auto Unseal and
  Seal Wrapping.
