• (rope) remove a debug print left in materialize
• (lexer) a regex may follow the ) of a statement head
• (intl) DateTimeFormat formatToParts was missing numbering-system digits

• (intl) DisplayNames/supportedValuesOf agreement; -u-tz- alias names (+2)
• (regexp) @@replace must carry WTF-8, and concatenate it canonically
• (parser) carry program text as WTF-8 so lone surrogates survive (+9)
• (realm/temporal) swap intrinsics on realm entry; Table 6 month-day (+17)
• (annexB) per-realm RegExp brand check; B.3.5 for-in initializer (+7)

• (async) PromiseResolve must observe constructor; async-generator ticks (+13)
• (scope) Annex B.3.3 block-function hoisting is sloppy-only (+6)
• (lexer) a class body's } ends a statement, so / after it is a regex (+4)
• (module) evaluate a deferred import's async dependencies (+8)
• (intl) apply the locale's collation tailoring
• (shape) break the parent/transition reference cycle
• (array) Array.fromAsync suspends at each Await (+4)
