+Alongside many enhancements to NixOS modules and general system improvements, this release features the following highlights:
+
 - NixOS now has initial support for the [**COSMIC DE**](https://system76.com/cosmic) which is currently at **Alpha 7**. COSMIC is a Rust-based Desktop Environment by System76, makers of Pop!_OS. You can use COSMIC by enabling the greeter (login manager) with [](#opt-services.displayManager.cosmic-greeter.enable), and the DE itself by enabling [](#opt-services.desktopManager.cosmic.enable). The support in NixOS/Nixpkgs is stable but still considered experimental because of the recent the addition. The COSMIC maintainers will be waiting for one more release of NixOS to determine if the experimental tag should be removed or not. Until then, please report any issues to the [COSMIC DE tracker in Nixpkgs](https://github.com/NixOS/nixpkgs/issues/259641) instead of upstream.
 
 - `nixos-rebuild-ng`, a full rewrite of `nixos-rebuild` in Python, is available for testing. You can enable it by setting [](#opt-system.rebuild.enableNg) in your configuration (this will replace the old `nixos-rebuild`), or by adding `nixos-rebuild-ng` to your `environment.systemPackages` (in this case, it will live side-by-side with `nixos-rebuild` as `nixos-rebuild-ng`). It is expected that the next major version of NixOS (25.11) will enable `system.rebuild.enableNg` by default.
 
-- The `nixos-generate-config` command now supports a optional `--flake` option, which will generate a flake.nix file alongside the `configuration.nix` and `hardware-configuration.nix`, providing an easy introduction into flake-based system configurations.
-
 - A `nixos-rebuild build-image` sub-command has been added.
   It allows users to build platform-specific (disk) images from their NixOS configurations. `nixos-rebuild build-image` works similar to the popular [nix-community/nixos-generators](https://github.com/nix-community/nixos-generators) project. See new [section on image building in the NixOS manual](#sec-image-nixos-rebuild-build-image). It is also available for `nixos-rebuild-ng`.

-- The `intel` video driver for X.org (from the xf86-video-intel package, which was previously removed because it was non-functional) has been fixed and the driver has been re-introduced.
+- [channels.nixos.org](https://channels.nixos.org) now supports the Lockable HTTP Tarball Protocol. This allows using the channel `nixexprs.tar` as Nix Flake input, e.g.:
+  ```
+  inputs.nixpkgs.url = "https://channels.nixos.org/nixos-25.05/nixexprs.tar.xz";

 - PAM services for `i3lock`/`i3lock-color`, `vlock`, `xlock`, and `xscreensaver` now default to disabled unless other corresponding NixOS options are set (`programs.i3lock.enable`, `console.enable`, `services.xserver.enable`, and `services.xscreensaver.enable`, respectively). If for some reason you want one of them back without setting the corresponding option, set, e.g., `security.pam.services.xlock.enable = true`.

 - [`system.stateVersion`](#opt-system.stateVersion) is now validated and must be in the `"YY.MM"` format, ideally corresponding to a prior NixOS release.
 
 - [`hardware.xone`](options.html#opt-hardware.xone.enable) will also enable [`hardware.xpad-noone`](options.html#opt-hardware.xpad-noone.enable) to provide Xbox 360 driver by default.

 - systemd's {manpage}`systemd-ssh-generator(8)` now works out of the box on NixOS.
   - You can ssh into VMs without any networking configuration if your hypervisor configures the vm to support AF_VSOCK.
     It still requires the usual ssh authentication methods.
