 * Added `Name` methods `toLowerString()` and `isSpecialClassName()`.
 * Added `Identifier` and `VarLikeIdentifier` nodes, which are used in place of simple strings in
   many places.
+* Added `getComments()`, `getStartLine()`, `getEndLine()`, `getStartTokenPos()`, `getEndTokenPos()`,
+  `getStartFilePos()` and `getEndFilePos()` methods to `Node`. These provide a more obvious access
+  point for the already existing attributes of the same name.
 
 ### Changed
 

UPGRADE-4.0.md

 * The `alias` subnode of `UseUse` is now `null` if no explicit alias is given. As such,
   `use Foo\Bar` and `use Foo\Bar as Bar` are now represented differently. The `getAlias()` method
   can be used to get the effective alias, even if it is not explicitly given.
+
+### Miscellaneous
+
+* The indenentation handling in the pretty printer has been changed (this is only relevant if you
+  extend the pretty printer). Previously indentation was automatic, and parts were excluded using
+  `pNoindent()`. Now no-indent is the default and newlins that require indentation should use
+  `$this->nl`.
 
 ### Removed functionality
