* 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 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
