Backward Incompatibilities in NixOS 24.11 (Continued)

- [Glances](https://github.com/nicolargo/glances), an open-source system cross-platform monitoring tool. Available as [services.glances](options.html#opt-services.glances). ## Backward Incompatibilities {#sec-release-24.11-incompatibilities} - Nixpkgs now requires Nix 2.3.17 or newer to allow for zstd compressed binary artifacts. - The `sound` options have been removed or renamed, as they had a lot of unintended side effects. See [below](#sec-release-24.11-migration-sound) for details. - The NVIDIA driver no longer defaults to the proprietary kernel module with versions >= 560. You will need to manually set `hardware.nvidia.open` to select the proprietary or open modules. - The `intel` driver for the X server (`services.xserver.videoDrives = [ "intel" ]`) is no longer functional due to incompatibilities with the latest Mesa version. All users are strongly encouraged to switch to the generic `modesetting` driver (the default one) whenever possible, for more information see the manual chapter on [Intel Graphics](#sec-x11--graphics-cards-intel) and issue [#342763](https://github.com/NixOS/nixpkgs/issues/342763). - The `intel-compute-runtime` package dropped support for older GPUs, and only supports 12th Gen and newer from now on. Intel GPUs from Gen 8,9 and 11 need to use the `intel-compute-runtime-legacy1` package in `hardware.graphics.extraPackages`. - The `(buildPythonPackage { ... }).override` and `(buildPythonPackage { ... }).overrideDerivation` attributes is now deprecated and removed in favour of `overridePythonAttrs` and `lib.overrideDerivation`. This change does not affect the override interface of most Python packages, as [`<pkg>.override`](https://nixos.org/manual/nixpkgs/unstable/#sec-pkg-override) provided by `callPackage` shadows such a locally-defined `override` attribute. The `<pkg>.overrideDerivation` attribute of Python packages called with `callPackage` will also remain available after this change. - All Cinnamon and XApp packages have been moved to top-level (i.e., `cinnamon.nemo` is now `nemo`). - All GNOME packages have been moved to top-level (i.e., `gnome.nautilus` is now `nautilus`). - `transmission` has been aliased with a `trace` warning to `transmission_3`, since [Transmission 4 has been released last year](https://github.com/transmission/transmission/releases/tag/4.0.0) and Transmission 3 will eventually go away -- this is meant to make people aware of the new version. `services.transmission.package` now also defaults to `transmission_3`, as the upgrade can cause data loss in some cases (examples: [#5153](https://github.com/transmission/transmission/issues/5153), [#6796](https://github.com/transmission/transmission/issues/6796)). Please make sure to back up to your data directory if you may be affected: - `transmission-gtk`: `~/.config/transmission` - `transmission-daemon` using NixOS module: `${config.services.transmission.home}/.config/transmission-daemon` (defaults to `/var/lib/transmission/.config/transmission-daemon`) - The default `mongodb` version has been updated from 5.0 to 7.0. For more information, see the compatibility changes for MongoDB [6.0](https://www.mongodb.com/docs/manual/release-notes/6.0-compatibility/) and [7.0](https://www.mongodb.com/docs/manual/release-notes/7.0-compatibility/). - `unifi` has been updated to UniFi 8. `unifi7` was removed as it is vulnerable to CVE-2024-42025 and required a version of MongoDB that has reached end of life. - `androidenv.androidPkgs_9_0` has been removed. It is replaced with `androidenv.androidPkgs` for a more complete Android SDK, including support for Android 9 and later. - The VirtualBox demo installer appliance has been removed. Please use the standard installer ISOs instead. - `grafana` has been updated to version 11.3. This version doesn't support setting `http_addr` to a hostname anymore, an IP address is expected. - `deno` has been updated to Deno 2, which has breaking changes. See the [migration guide](https://docs.deno.com/runtime/reference/migration_guide/) for details.

This section details backward incompatibilities introduced in NixOS 24.11. These include requirements for newer versions of Nix, changes to sound options, NVIDIA driver defaults, the removal of the intel X server driver, and dropping support for older Intel GPUs in the intel-compute-runtime package. It also covers deprecation of python package overrides, moving Cinnamon and GNOME packages to top-level, aliasing transmission to transmission_3, updating MongoDB to 7.0 and UniFi to version 8, removing androidPkgs_9_0, the VirtualBox demo installer, grafana updates, and breaking changes in Deno 2.
