 - 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`. Additionally, `pgvecto-rs` support is now disabled from NixOS 25.11 onwards using the option `services.immich.database.enableVectors`. This option will be removed fully in the future once Immich drops support for `pgvecto-rs` fully. See [Immich migration instructions](#module-services-immich-vectorchord-migration)
 
+- `services.restic.backups` now includes a `command` option for passing a command to the [--stdin-from-command](https://github.com/restic/restic/pull/4410) flag.

 - `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.
