-Version 3.0.5-dev
+Version 3.1.3-dev
 -----------------
 
 Nothing yet.
 
+Version 3.1.2 (2017-11-04)
+--------------------------
+
+### Fixed
+
+* Comments on empty blocks are now preserved on a `Stmt\Nop` node. (#382)
+
+### Added
+
+* Added `kind` attribute for `Stmt\Namespace_` node, which is one of `KIND_SEMICOLON` or
+  `KIND_BRACED`. (#417)
+* Added `setDocComment()` method to namespace builder. (#437)
+
+Version 3.1.1 (2017-09-02)
+--------------------------
+
+### Fixed
+
+* Fixed syntax error on comment after brace-style namespace declaration. (#412)
+* Added support for TraitUse statements in trait builder. (#413)
+
+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.
+
+Version 3.0.6 (2017-06-28)
+--------------------------
+
+### Fixed
+
+* Fixed the spelling of `Class_::VISIBILITY_MODIFIER_MASK`. The previous spelling of
+  `Class_::VISIBILITY_MODIFER_MASK` is preserved for backwards compatibility.
+* The pretty printing will now preserve comments inside array literals and function calls by
+  printing the array items / function arguments on separate lines. Array literals and functions that
+  do not contain comments are not affected.
+
+### Added
+
+* Added `Builder\Param::makeVariadic()`.
+
+### Deprecated
+
+* The `Node::setLine()` method has been deprecated.
+
+Version 3.0.5 (2017-03-05)
+--------------------------
+
+### Fixed
+
+* Name resolution of `NullableType`s is now performed earlier, so that a fully resolved signature is
+  available when a function is entered. (#360)
+* `Error` nodes are now considered empty, while previously they extended until the token where the
+  error occurred. This made some nodes larger than expected. (#359)
+* Fixed notices being thrown during error recovery in some situations. (#362)
+
 Version 3.0.4 (2017-02-10)
