+# Release 2.10 (2022-07-11)
+
+* `nix repl` now takes installables on the command line, unifying the usage
+  with other commands that use `--file` and `--expr`. Primary breaking change
+  is for the common usage of `nix repl '<nixpkgs>'` which can be recovered with
+  `nix repl --file '<nixpkgs>'` or `nix repl --expr 'import <nixpkgs>{}'`.
+
+  This is currently guarded by the `repl-flake` experimental feature.
+
+* A new function `builtins.traceVerbose` is available. It is similar
+  to `builtins.trace` if the `trace-verbose` setting is set to true,
+  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`.
+
+* Nix can now be built with LTO by passing `--enable-lto` to `configure`.
+  LTO is currently only supported when building with GCC.

-
 * `nix copy` now copies the store paths in parallel as much as possible (again).
   This doesn't apply for the `daemon` and `ssh-ng` stores which copy everything
-  in one batch to avoid latencies issues.
