`v1.89.1` is a patch release on top of [`v1.89.0`](/release_notes/v1.89.0/v1-89-0). It brings the 1.84.8 database-resilience set onto the 1.89 line, hardens the MCP OAuth and credential paths, aligns the `/v1/model/info` and `/v2/model/info` surfaces, adds the budget-reservation toggle, and refreshes dependencies.
