# @theorchard/backend-m2m-token-manager

## 0.9.0

### Minor Changes

- PP-1385 Update ImpersonationM2MTokenManager to perform retries when generating an Impersonation JWT. This handles when Auth0 returns 429 (Too Many Requests), 502, 503, 504 HTTP Status Codes, which are indicative of Auth0 having too much load, and needing clients to back-off.
- Update the getBackoffWithFullJitter (private method) to return in milliseconds unit
- Update the Auth0TokenException to take ErrorOptions as opposed to a detail string

## 0.8.0

### Minor Changes

- PP-1201: Enable injecting a Logger to M2MTokenManager.

The `M2MTokenManager` constructor now accepts an optional `logger` parameter that
implements the `Logger` interface. If not provided, a `ConsoleLogger` is used by default.
This allows clients to integrate their own logging implementations for better observability of
token management operations.
