+* On Linux, Nix can now run builds in a user namespace where they run
+  as root (UID 0) and have 65,536 UIDs available.
+  <!-- FIXME: move this to its own section about system features -->
+  This is primarily useful for running containers such as `systemd-nspawn`
+  inside a Nix build. For an example, see [`tests/systemd-nspawn/nix`][nspawn].

+
+  A build can enable this by setting the derivation attribute:
+
+  ```
+  requiredSystemFeatures = [ "uid-range" ];
+  ```
+
+  The `uid-range` [system feature] requires the [`auto-allocate-uids`]
+  setting to be enabled.
+
+  [system feature]: (../command-ref/conf-file.md#conf-system-features)

+* Nix can now automatically pick UIDs for builds, removing the need to
+  create `nixbld*` user accounts. See [`auto-allocate-uids`].
+
+  [`auto-allocate-uids`]: (../command-ref/conf-file.md#conf-auto-allocate-uids)

+* On Linux, Nix has experimental support for running builds inside a
+  cgroup. See
+  [`use-cgroups`](../command-ref/conf-file.md#conf-use-cgroups).
+
+* `<nix/fetchurl.nix>` now accepts an additional argument `impure` which
+  defaults to `false`.  If it is set to `true`, the `hash` and `sha256`
+  arguments will be ignored and the resulting derivation will have
+  `__impure` set to `true`, making it an impure derivation.
+
+* If `builtins.readFile` is called on a file with context, then only
+  the parts of the context that appear in the content of the file are
+  retained.  This avoids a lot of spurious errors where strings end up
+  having a context just because they are read from a store path
+  ([#7260](https://github.com/NixOS/nix/pull/7260)).
+
+* `nix build --json` now prints some statistics about top-level
+  derivations, such as CPU statistics when cgroups are enabled.
