v2.5.0

Added

• Support the readonly modifier on class and trait properties: readonly is a property modifier keyword that appears in the property visibility list (e.g. public readonly int x), independent of position relative to public/protected/private and combining with every property type prefix (builtin, ?type, <Class> cast and union). The parser only records the modifier; the typed / no-default / no-static rules are enforced by the compiler (zephir-lang/zephir#2614).

Changed

• readonly is now a reserved keyword; identifiers named readonly are a syntax error.
