Vault 1.9.0 released

Hi folks,

The Vault team is happy to announce the release of Vault 1.9!

Open-source binaries can be downloaded at [1]. Enterprise binaries are available to customers as well.

As a reminder, if you believe you have found a security issue in Vault, please responsibly disclose by emailing and do not use the public issue tracker. Our security policy and our PGP key can be found at [2].

In 1.9.0 we have added a documentation page covering some planned deprecations [8]. Please review this page.

The key fixes and improvements in this release are:

  • Customizable HTTP Headers: Users can now customize HTTP headers returned from the Vault server for the full range of Vault endpoints
  • KVv2 - Custom Metadata: The KvV2 secrets engine now allows custom metadata defined by users
  • KVv2 - HTTP PATCH (Tech Preview): The KVv2 secrets engine now supports partial updates via HTTP PATCH
  • Namespace API Lock (Enterprise): Vault has added the capability to lock API access at the namespace level
  • UI Support for Databases: The UI now supports Elasticsearch, Oracle, and Postgres database plugins
  • Updated UI for KV Secret Engine: The KV secret engine has a new streamlined workflow, with the ability to add custom metadata, a separate tab for viewing metadata per secret, and other updates.
  • PKI Secrets Engine (UI): Updated UI for the PKI Secrets Engine to display certificate metadata for common name, issue date, expiration date, and serial number.
  • Client Count: Many improvements across the UI for seeing clients per namespace, data export option, and view totals earlier than month end. Updated formula for handling non-entity tokens.
  • OIDC Provider (Tech Preview): Vault can now act as an OIDC provider. Applications that support OIDC can now delegate authentication to Vault using OIDC.
  • Key Management Secrets Engine (Enterprise): The Key Management Secrets Engine now supports distributing keys to GCP KMS
  • Azure Secrets: Support for rotating the root password has been added. Additionally, the engine has been updated to support the Microsoft Graph APIs.
  • Transform Secrets Engine (Enterprise): Added advanced handling of encode and decode in format preserving encryption (FPE), including support for roles that can partially decode.

See the Changelog at [3] for the full list of improvements and bug fixes.

See the Feature Deprecation Notice and Plans page [8] for our upcoming feature deprecation plans.

OSS [5] and Enterprise [6] Docker images will be available soon.


See [4] for general upgrade instructions.

As always, we recommend upgrading and testing this release in an isolated environment. If you experience any non-security issues, please report them on the Vault GitHub issue tracker or post to the Vault Discuss Forum at [7].

We hope you enjoy Vault 1.9!
