+How do I install packages from Nixpkgs unstable?
+------------------------------------------------
+
+If you are using a stable version of Nixpkgs but would like to install
+some particular packages from Nixpkgs unstable then you can import the
+unstable Nixpkgs and refer to its packages within your configuration.
+Something like
+
+```nix
+{ pkgs, config, ... }:
+
+let
+
+  pkgsUnstable = import <nixpkgs-unstable> {};
+
+in
+
+{
+  home.packages = [
+    pkgsUnstable.foo
+  ];
+
+  # …
+}
+```
+
+should work provided you have a Nix channel called `nixpkgs-unstable`.
+Note, the package will not be affected by any package overrides,
+overlays, etc.

+=== Highlights
+
+This release has the following notable changes:
+
+* The <<opt-programs.firefox.enableGoogleTalk>> and
+  <<opt-programs.firefox.enableIcedTea>> options are now deprecated
+  and will only work if Firefox ESR 52.x is used.
+
+* The `home-manager` tool now provides an `uninstall` sub-command that
+  can be used to uninstall Home Manager, if used in the standalone
+  mode. That is, not as a NixOS module.
