+Version 3.1.0 (2017-07-28)
+--------------------------
+
 ### Added
 
 * [PHP 7.2] Added support for trailing comma in group use statements.
 * [PHP 7.2] Added support for `object` type. This means `object` types will now be represented as a
   builtin type (a simple `"object"` string), rather than a class `Name`.
+  
+### Fixed
+
+* Floating-point numbers are now printed correctly if the LC_NUMERIC locale uses a comma as decimal
+  separator.
+
+### Changed
+
+* `Name::$parts` is no longer deprecated.
