Revision history for Perl extension Promise::XS:

0.08
- MAJOR BREAKING CHANGE: Callbacks now run in scalar context. The prior
  behavior of running in list context allowed for weirdness like
  returning a promise plus additional items, in whatever order. Proper
  behavior in this case isn’t clear from Promises/A+, and iterating through
  the return to warn or fail would slow everything down. Scalar context
  conduces to more robust usage and hews closer to both Promises/A+ and
  ECMAScript standards.
- MAJOR BREAKING CHANGE: Due to the above change, all()/collect() now
  resolves with an array reference of the promise returns.
- BREAKING CHANGE (minor): finally() now mimics ECMAScript’s interface.
  That means:
    * Callbacks now receive no arguments.
    * Returned promises resolve with the original value if the callback
      returns anything but a promise that rejects.
