v2.0.0

Changelog

This is a completely rewritten version of Promise in python, based in the ultra-performant and low-memory bluebird.js promise implementation.

• New dataloader implementation
• Promise.resolve now acts the same as Promise.cast
• Promise.reject is now a static method (instead of a instance one, like in previous versions)
• New Promise.all fast implementation.
• promise.get raised exceptions now include traceback.
• Custom schedulers for Promise resolution.

Deprecation

• Promise.promisify is now a function wrapper, that executes the function, but returning a Promise. Calling Promise.promisify on a static value will be deprecated in next versions.
• promise.fulfill is renamed to promise.do_fulfill
• promise.rejected/promise.reject is renamed to promise.do_reject
