Changes for version 0.19

  • BREAKING CHANGE / BUG FIX: finally() now matches the ES6 standard better. While the erstwhile differences weren’t documented, they’re salient enough to be noticeable. That said, it seems unlikely that anything depended on the old (useless?) behavior.
    • Its callback no longer receives any arguments.
    • Its callback runs in void context.
    • Its returned promise now duplicates the original if the callback succeeds. This means that unhandled rejection warnings will now fire correctly from finally().
  • BUG FIX: all() and race() now correctly handle all promises’ rejections.
  • Anything that has a then() method is now regarded as a promise. This allows easier compatibility with other promise implementations.
  • All unresolved promises—including those resolved immediately—now prompt uncaught-rejection warnings. The prior behavior of suppressing the warning for immediately-rejected promises made sense under initial implementations of the uncaught-rejection warning but now appears to serve no useful end.
