+# Release 2.18 (2023-09-20)
+
+- Two new builtin functions,
+  [`builtins.parseFlakeRef`](@docroot@/language/builtins.md#builtins-parseFlakeRef)
+  and
+  [`builtins.flakeRefToString`](@docroot@/language/builtins.md#builtins-flakeRefToString),
+  have been added.
+  These functions are useful for converting between flake references encoded as attribute sets and URLs.
+
+- [`builtins.toJSON`](@docroot@/language/builtins.md#builtins-parseFlakeRef) now prints [--show-trace](@docroot@/command-ref/conf-file.html#conf-show-trace) items for the path in which it finds an evaluation error.
+
+- Error messages regarding malformed input to [`nix derivation add`](@docroot@/command-ref/new-cli/nix3-derivation-add.md) are now clearer and more detailed.
+
+- The `discard-references` feature has been stabilized.
+  This means that the
+  [unsafeDiscardReferences](@docroot@/contributing/experimental-features.md#xp-feature-discard-references)
+  attribute is no longer guarded by an experimental flag and can be used
+  freely.
+
+- The JSON output for derived paths which are store paths is now a string, not an object with a single `path` field.
+  This only affects `nix-build --json` when "building" non-derivation things like fetched sources, which is a no-op.
+
+- A new builtin [`outputOf`](@docroot@/language/builtins.md#builtins-outputOf) has been added.
+  It is part of the [`dynamic-derivations`](@docroot@/contributing/experimental-features.md#xp-feature-dynamic-derivations) experimental feature.
+
+- Flake follow paths at depths greater than 2 are now handled correctly, preventing "follows a non-existent input" errors.
+
+- [`nix-store --query`](@docroot@/command-ref/nix-store/query.md) gained a new type of query: `--valid-derivers`. It returns all `.drv` files in the local store that *can be* used to build the output passed in argument. This is in contrast to `--deriver`, which returns the single `.drv` file that *was actually* used to build the output passed in argument. In case the output was substituted from a binary cache, this `.drv` file may only exist on said binary cache and not locally.
