- Aligned invalid octal numbers checks to the specification
- BC break: identifier tokens' value now report their raw name, this means that unicode escape sequences are reported as they are written in the code, without converting them to their corresponding characters. Identifier nodes have a new property called
rawNamethat contains their raw name, including unconverted unicode escape sequences, while thenameproperty still contains the converted value as before. Renderer now printsrawNamefor identifiers to prevent automatic conversion of escaped keywords.
