* Nix can now be built with LTO by passing `--enable-lto` to `configure`.
LTO is currently only supported when building with GCC.

and it is a no-op otherwise.
* `nix search` has a new flag `--exclude` to filter out packages.
* On Linux, if `/nix` doesn't exist and cannot be created and you're
not running as root, Nix will automatically use
`~/.local/share/nix/root` as a chroot store. This enables non-root
users to download the statically linked Nix binary and have it work
out of the box, e.g.
```
# ~/nix run nixpkgs#hello
warning: '/nix' does not exists, so Nix will use '/home/ubuntu/.local/share/nix/root' as a chroot store
Hello, world!
```
* `flake-registry.json` is now fetched from `channels.nixos.org`.
