@ -35,6 +35,10 @@ In addition to numerous new and upgraded packages, this release has the followin
for a transition period so that in time the ecosystem can switch without
breaking compatibility with any supported NixOS release.
- `emacs` enables native compilation which means:
- emacs packages from nixpkgs, builtin or not, will do native compilation ahead of time so you can enjoy the benefit of native compilation without compiling them on you machine;
- emacs packages from somewhere else, e.g. `package-install`, will do asynchronously deferred native compilation. If you do not want this, maybe to avoid CPU consumption for compilation, you can use `(setq native-comp-deferred-compilation nil)` to disable it while still enjoy the benefit of native compilation for packages from nixpkgs.
- `nixos-generate-config` now generates configurations that can be built in pure
mode. This is achieved by setting the new `nixpkgs.hostPlatform` option.
