+# 0.51.1
+
+Released 2019/09/23.
+
+## Fixed
+
+ * Mismatched `Ord` and `PartialOrd` implementations were fixed, which regresses
+   bindgen in funny ways when using rustc nightly. Dot releases for a few of the
+   previous versions of bindgen will be created with this fix. [#1627][]
+
+## Changed
+
+ * Syn and related dependencies have been updated. [#1611][]
+
+ * Switches added to allow less dependencies. In
+   particular: It won't pull `failure` and related dependencies by default, and
+   there's a default-on `which-rustfmt` feature which allows to get rid of
+   `which` altogether. [#1615][] / [#1625][]
+
+ * `fxhash` dependency was switched to `rustc-hash`. [#1626][]
