 - `services.ntpd-rs` now performs configuration validation.
 
+- Immich now has support for [VectorChord](https://github.com/tensorchord/VectorChord) when using the PostgreSQL configuration provided by `services.immich.database.enable`, which replaces `pgvecto-rs`. VectorChord support can be toggled with the option `services.immich.database.enableVectorChord`.

 - `services.postsrsd` now automatically integrates with the local Postfix instance, when enabled. This behavior can disabled using the [services.postsrsd.configurePostfix](#opt-services.postsrsd.configurePostfix) option.
 
 - `services.pfix-srsd` now automatically integrates with the local Postfix instance, when enabled. This behavior can disabled using the [services.pfix-srsd.configurePostfix](#opt-services.pfix-srsd.configurePostfix) option.
