-Version 1.1.1-dev
+Version 1.3.1-dev
 -----------------
 
 Nothing yet.
 
+Version 1.3.0 (2015-05-02)
+--------------------------
+
+### Added
+
+* Errors can now store the attributes of the node/token where the error occurred. Previously only the start line was
+  stored.
+* If file positions are enabled in the lexer, errors can now provide column information if it is available. See
+  [documentation](https://github.com/nikic/PHP-Parser/blob/master/doc/component/Error.markdown#column-information).
+* The parser now provides an experimental error recovery mode, which can be enabled by disabling the `throwOnError`
+  parser option. In this mode the parser will try to construct a partial AST even if the code is not valid PHP. See
+  [documentation](https://github.com/nikic/PHP-Parser/blob/master/doc/component/Error.markdown#error-recovery).
+* Added support for PHP 7 `yield from` expression. It is represented by `Expr\YieldFrom`.
+* Added support for PHP 7 anonymous classes. These are represented by ordinary `Stmt\Class_` nodes with the name set to
+  `null`. Furthermore this implies that `Expr\New_` can now contain a `Stmt\Class_` in its `class` subnode.
+
+### Fixed
+
+* Fixed registration of PHP 7 aliases, for the case where the old name was used before the new name.
+* Fixed handling of precedence when pretty-printing `print` expressions.
+* Floating point numbers are now pretty-printed with a higher precision.
+* Checks for special class names like `self` are now case-insensitive.
+
+Version 1.2.2 (2015-04-03)
+--------------------------
+
+* The `NameResolver` now resolves parameter type hints when entering the function/method/closure node. As such other
+  visitors running after it will be able to make use of the resolved names at that point already.
+* The autoloader no longer sets the `unserialize_callback_func` ini option on registration - this is not necessary and
+  may cause issues when running PhpUnit tests with process isolation.
+
+Version 1.2.1 (2015-03-24)
+--------------------------
+
+* Fixed registration of the aliases introduced in 1.2.0. Previously the old class names could not be used in
+  `instanceof` checks under some circumstances.
+
+Version 1.2.0 (2015-03-22)
+--------------------------
+
+### Changed
+
+* To ensure compatibility with PHP 7, the following node classes have been renamed:
+
+        OLD                             => NEW
+        PhpParser\Node\Expr\Cast\Bool   => PhpParser\Node\Expr\Cast\Bool_
+        PhpParser\Node\Expr\Cast\Int    => PhpParser\Node\Expr\Cast\Int_
+        PhpParser\Node\Expr\Cast\Object => PhpParser\Node\Expr\Cast\Object_
+        PhpParser\Node\Expr\Cast\String => PhpParser\Node\Expr\Cast\String_
+        PhpParser\Node\Scalar\String    => PhpParser\Node\Scalar\String_
+
+  **The previous class names are still supported as aliases.** However it is strongly encouraged to use the new names
+  in order to make your code compatible with PHP 7.
+
+* Subnodes are now stored using real properties instead of an array. This improves performance and memory usage of the
+  initial parse and subsequent node tree operations. The `NodeAbstract` class still supports the old way of specifying
+  subnodes, however this is *deprecated*. In any case properties that are assigned to a node after creation will no
+  longer be considered as subnodes.
+
+* Methods and property declarations will no longer set the `Stmt\Class_::MODIFIER_PUBLIC` flag if no visibility is
+  explicitly given. However the `isPublic()` method will continue to return true. This allows you to distinguish whether
+  a method/property is explicitly or implicitly public and control the pretty printer output more precisely.
+
+* The `Stmt\Class_`, `Stmt\Interface_` and `Stmt\Trait_` nodes now inherit from `Stmt\ClassLike`, which provides a
+  `getMethods()` method. Previously this method was only available on `Stmt\Class_`.
+
+* Support including the `bootstrap.php` file multiple times.
+
+* Make documentation and tests part of the release tarball again.
+
+* Improve support for HHVM and PHP 7.
+
+### Added
+
+* Added support for PHP 7 return type declarations. This adds an additional `returnType` subnode to `Stmt\Function_`,
+  `Stmt\ClassMethod` and `Expr\Closure`.
+
+* Added support for the PHP 7 null coalesce operator `??`. The operator is represented by `Expr\BinaryOp\Coalesce`.
+
+* Added support for the PHP 7 spaceship operator `<=>`. The operator is represented by `Expr\BinaryOp\Spaceship`.
+
+* Added use builder.
+
+* Added global namespace support to the namespace builder.
+
+* Added a constructor flag to `NodeTraverser`, which disables cloning of nodes.
+
 Version 1.1.0 (2015-01-18)
 --------------------------
 
 * Methods that do not specify an explicit visibility (e.g. `function method()`) will now have the `MODIFIER_PUBLIC`
   flag set. This also means that their `isPublic()` method will return true.
 
-* Declaring a property as abstract or static is now an error.
+* Declaring a property as abstract or final is now an error.
 
 * The `Lexer` and `Lexer\Emulative` classes now accept an `$options` array in their constructors. Currently only the
   `usedAttributes` option is supported, which determines which attributes will be added to AST nodes. In particular
