Version 3.0.0-alpha.9
------------------
* 403 358 549 Make all names nodes: either SimpleName or Name. This makes every name in the AST visitable. NameExpr is now a wrapper to use SimpleName in an expression.
* 516 536 use Optional<> for return values.
* 556 557 558 550 small improvements and fixes.
* 560 559 make nodes observable.

Version 3.0.0-alpha.8
------------------
* 344 529 turn DumpVisitor into an official PrettyPrinter
* 532 508 427 530 531 513 528 cleanups

Version 3.0.0-alpha.7
------------------
* 515 roll back attempt at using Optional
* 522 504 make NodeList not a Node (restores parent/children behaviour to before alpha.4)
* 527 526 rename getChildrenNodes to getChildNodes
* 525 495 520 bug fix

Version 3.0.0-alpha.6
------------------
* 503 modified ImportDeclaration hierarchy to have getters for static and "asterisk" again
* 506 bug fix

Version 3.0.0-alpha.5
------------------
* 451 null is no longer allowed in the AST. [See last post in issue](https://github.com/javaparser/javaparser/issues/451)
* 501 421 420 316 use a special type of list for nodes: NodeList. [See last post in issue](https://github.com/javaparser/javaparser/issues/421)

Version 3.0.0-alpha.4
------------------
* 463 471 nodes can now be removed easily
* 491 import handling changed. Instead of "ImportDeclaration", we now have the four types of import as described in the JLS. [See issue](https://github.com/javaparser/javaparser/pull/491)
* 452 355 474 494 various improvements
* 493 492 485 Simplify the JavaParser interface

Version 3.0.0-alpha.3
------------------
* 112 237 466 465 461 460 458 457 fundamentally changes how we deal with arrays. [It is explained in the last post here](https://github.com/javaparser/javaparser/issues/237)
* 472 456 makes the "data" field on every node more structured.
* 477 468 refactor TypeArguments. You will find that TypeArguments is no longer a type, it is just a list in some nodes.
* 482 adds the "nodeTypes" packages to the osgi export.
* 479 476 makes all setters on nodes return this so they become chainable.
* 473 437 clean up CloneVisitor.

Version 3.0.0-alpha.2

* 400 405 introduce many "builder" style methods for constructing code. Thanks DeepSnowNeeL!
* 409 remove ASTHelper (methods are now on specific Node subclasses)
* 414 JavaParser can now be instantiated and reused. InstanceJavaParser removed
* 418 417 411 408 bugs
