## Release Notes: SeaORM 2.0.0-rc.26

*(since 2.0.0-rc.25)*

### New Features

**PostgreSQL legacy serial primary key option**

Added the `postgres-use-serial-pk` feature flag to use legacy `serial` / `bigserial` types for auto-increment primary keys instead of `GENERATED BY DEFAULT AS IDENTITY`. Enable with `postgres-use-serial-pk` in your `Cargo.toml` if you need compatibility with older PostgreSQL setups or tooling.
