* `nix store make-content-addressable` has been renamed to `nix store
make-content-addressed`.
+
+* New builtin function `builtins.fetchClosure` that copies a closure
+ from a binary cache at evaluation time and rewrites it to
+ content-addressed form (if it isn't already). Like
+ `builtins.storePath`, this allows importing pre-built store paths;
+ the difference is that it doesn't require the user to configure
+ binary caches and trusted public keys.
