Release notes

Sourced from nikic/php-parser's releases.

PHP-Parser 5.8.0

Fixed

• Treat _ as label character in formatting-preserving pretty printer.
• Handle comment after object operator in keyword emulator.

Changed

• Drop support for pipe operator in constant expression evaluator. It is not supported in constant expressions and may pose security risks, as it allows calls to arbitrary functions.
• void parameter types now generate a (recoverable) error during parsing.
• Restored reverse emulation support for fn keywords when targeting PHP before 7.4.
