bluebird

Features:

• New method: .value()
• New method: .reason()
• New method: Promise.onUnhandledRejectionHandled()
• Promise.map(), .map(), Promise.filter() and .filter() start calling their callbacks as soon as possible while retaining a correct order. See 8085922f.

Bugfixes:

• Fix #165
• Fix #166

Bugfixes:

• #138
• #144
• #148
• #151

Features:

• Implement Promise.prototype.tap()
• Implement Promise.coroutine.addYieldHandler()
• Deprecate Promise.prototype.spawn

Bugfixes:

• Fix already rejected promises being reported as unhandled when handled through collection methods
• Fix browserisfy crashing from checking process.version.indexOf

Bugfixes:

• Fix active domain being lost across asynchronous boundaries in Node.JS 10.xx

Bugfixes:

• Fix handled errors being reported

Features:

• Node.js performance: promisified functions try to check amount of passed arguments in most optimal order
• Node.js promisified functions will have same .length as the original function minus one (for the callback parameter)

Features:

• Possibly unhandled rejection handler will always get a stack trace, even if the rejection or thrown error was not an error
• Unhandled rejections are tracked per promise, not per error. So if you create multiple branches from a single ancestor and that ancestor gets rejected, each branch with no error handler with the end will cause a possibly unhandled rejection handler invocation

Bugfixes:

• Fix unhandled non-writable objects or primitives not reported by possibly unhandled rejection handler

Bugfixes:

• #93

Features:

• Significantly improve performance of foreign bluebird thenables

Bugfixes:

• #88

Features:

• Error objects that have property .isAsync = true will now be caught by .error()

Bugfixes:

• Fix TypeError and RangeError shims not working without new operator

Features:

• .filter, .map, and .reduce no longer skip sparse array holes. This is a backwards incompatible change.
• Like .map and .filter, .reduce now allows returning promises and thenables from the iteration function.

Bugfixes:

• #58
• #61
• #64
• #60

Features:

• You may now return promises and thenables from the filterer function used in Promise.filter and Promise.prototype.filter.

• .error() now catches additional sources of rejections:

  • Rejections originating from Promise.reject

  • Rejections originating from thenables using the reject callback

  • Rejections originating from promisified callbacks which use the errback argument

  • Rejections originating from new Promise constructor where the reject callback is called explicitly

  • Rejections originating from PromiseResolver where .reject() method is called explicitly

Bugfixes:

• Fix captureStackTrace being called when it was null
• Fix Promise.map not unwrapping thenables

Features:

• Improve performance of collection methods
• Improve performance of promise chains

Bugfixes:

• Fix Promise.some behavior with arguments like negative integers, 0...
• Fix stack traces of synchronously throwing promisified functions'

Features:

• Improve performance of generators

Bugfixes:

• Fix critical bug with collection methods.

Features:

• Improve performance of all collection methods

Features:

• Improve overall performance.
• Improve performance of promisified functions.
• Improve performance of catch filters.
• Improve performance of .finally.

Bugfixes:

• Fix .finally() rejecting if passed non-function. It will now ignore non-functions like .then.
• Fix .finally() not converting thenables returned from the handler to promises.
• .spread() now rejects if the ultimate value given to it is not spreadable.

Features:

• Improve overall performance when not using .bind() or cancellation.
• Promises are now not cancellable by default. This is backwards incompatible change - see .cancellable()
• Promise.delay
• .delay()
• .timeout()

Bugfixes:

• Fix race condition when mixing 3rd party asynchrony.

Bugfixes:

• Fix another bug with progression.

Bugfixes:

• Fix bug with progression.

Bugfixes:

• Fix .race() not propagating bound values.

Features:

• Improve performance of Promise.race

Bugfixes:

• Fixed Promise.promisifyAll invoking property accessors. Only data properties with function values are considered.

Features:

• Disable long stack traces in browsers by default. Call Promise.longStackTraces() to enable them.

Bugfixes:

• Fail early when new Promise is constructed incorrectly

Bugfixes:

• Promise.props now takes a thenable-for-collection
• All promise collection methods now reject when a promise-or-thenable-for-collection turns out not to give a collection

Features:

• All static collection methods take thenable-for-collection

Features:

• throw TypeError when thenable resolves with itself
• Make .race() and Promise.race() forever pending on empty collections

Bugfixes:

• Promise.resolve and PromiseResolver.resolve follow thenables too.

Bugfixes:

• Fix infinite loop when thenable resolves with itself

Bugfixes:

• Fix a file missing from build. (Critical fix)

Features:

• Remove dependency of es5-shim and es5-sham when using ES3.
