| - **PostgreSQL 14+ is now a hard requirement:** The `lib/pq` driver has been updated to v1.11.2, which only supports PostgreSQL 14 and newer. Previously, PostgreSQL 17.x was the "tested and default" version, but older versions (e.g., PostgreSQL 13) may have still worked. With this update, **operators running PostgreSQL 13 or older must upgrade their database before upgrading Nebraska**. ([#1300](https://github.com/flatcar/nebraska/pull/1300)) |
