backend/v3.0.4

Hanko v3 introduces native multi-tenancy, allowing a single Hanko API deployment to manage any number of isolated tenants. Each tenant has its own user pool and authentication configuration.

Previously, Hanko was designed as a single-tenant, cloud-native application. Scaling multiple projects required running separate Hanko API instances, which we managed in Hanko Cloud using our Kubernetes operator.

With Hanko v3, a single Hanko API instance can now serve either one tenant or multiple tenants.

## Multi-tenancy

* The Hanko API can manage a single tenant or multiple isolated tenants.
* Each tenant has its own user pool and authentication configuration.
* Tenant-specific configuration is stored in the database when running in multi-tenant mode.
* The Tenant Management API specification will be published separately.

## Single-tenant mode

Hanko v3 can still be deployed in single-tenant mode.

YAML-based configuration continues to work as before (refer to the [configuration options reference](https://github.com/teamhanko/hanko/wiki/config)), making it possible to upgrade without migrating tenant configuration into the database.

## Global configuration

Multi-tenant deployments still require a global configuration file or environment variables.

This configuration contains settings that apply to the entire Hanko API deployment rather than to an individual tenant, including:

* Database connection settings
* Server and infrastructure configuration
* Other cross-tenant settings

## Breaking changes

Deprecated API endpoints have been removed.

See the migration guide for details and instructions:
