Version 4.6.0 (2020-07-02)

Added

• [PHP 8.0] Added support for trailing commas in parameter lists.
• [PHP 8.0] Added support for constructor promotion. The parameter visibility is stored in Node\Param::$flags.

Fixed

• Comment tokens now always follow the PHP 8 interpretation, and do not include trailing whitespace.
• As a result of the previous change, some whitespace issues when inserting a statement into a method containing only a comment, and using the formatting-preserving pretty printer, have been resolved.

Version 4.5.0 (2020-06-03)

Added

• [PHP 8.0] Added support for the mixed type. This means mixed types are now parsed as an Identifier rather than a Name.
• [PHP 8.0] Added support for catching without capturing the exception. This means that Catch_::$var may now be null.
