# Feature Deprecation Notice and Plans

This announcement page is maintained and updated periodically to communicate important decisions made concerning End of Support(EoS) for Vault features as well as features we have removed or disabled from the product. We document the removal of features, enable the community with a plan and timeline for eventual deprecations, and supply alternative paths to explore and evaluate to minimize business disruptions. If you have questions or concerns about a deprecated feature, please create a topic on [the community forum](https://discuss.hashicorp.com/c/vault/30) or raise a ticket with your support team. Please refer to the [FAQ](/docs/deprecation/faq) page for frequently asked questions concerning Vault feature deprecations.
