v0.308.0

Parser:

• The 5 enum body ESTree node types (EnumBooleanBody, EnumNumberBody, EnumStringBody, EnumSymbolBody, EnumBigIntBody) have been replaced with a single EnumBody node. Its members property is a flat array of per-type member nodes (EnumBooleanMember, EnumNumberMember, EnumStringMember, EnumBigIntMember, EnumDefaultedMember). The explicitType property is now a string ("boolean", "number", "string", "symbol", "bigint") or null (previously a boolean). hasUnknownMembers remains a boolean. Several enum validation errors are no longer reported by the parser and are instead reported by the type checker.

Library Definitions:

• Add type definition for RegExp.escape()
