 - Ethercalc and its associated module have been removed, as the package is unmaintained and cannot be installed from source with npm now.
 
-- `services.headplane` has been updated to 0.6.2, which introduces several changes to the configuration schema:
-  - `services.headplane.settings.oidc.redirect_uri` is deprecated. Use `services.headplane.settings.server.base_url` instead; the OIDC redirect URI is now automatically derived from it. Ensure `base_url` is the bare host URL without the `/admin` suffix.
-  - `services.headplane.settings.oidc.user_storage_file` is deprecated. Headplane 0.6.2 still accepts it to migrate the old JSON user database into the new internal SQL database.
-  - `services.headplane.settings.oidc.strict_validation` is deprecated and has no effect.
-  - `services.headplane.settings.oidc.token_endpoint_auth_method` now defaults to `null` (auto-detection), which typically falls back to `client_secret_basic`. Previous versions defaulted to `client_secret_post`.
-  - `services.headplane.settings.integration.agent.cache_ttl` is deprecated and has no effect in 0.6.2.
-
 - `services.immich` no longer supports pgvecto.rs since the package has been removed from nixpkgs.
   As a result, options `services.immich.database.enableVectors` and `services.immich.database.enableVectorchord` have been removed, and VectorChord is now always used.
   If you have not completed the migration yet, ensure you completely remove the extension from your database before upgrading by following the [migration guide](https://github.com/NixOS/nixpkgs/blob/nixos-25.11/nixos/modules/services/web-apps/immich.md#migrating-from-pgvecto-rs-to-vectorchord-pre-2511-installations-module-services-immich-vectorchord-migration).
