1.3.0

New Features

• Add animationFrame yieldable helper. Yielding animationFrame() will
  pause a task until after the next animation frame using the native
  requestAnimationFrame() browser API.

  Note: ember-concurrency tasks are scheduled on the runloop, so this will
  not cause the remainder of the task to instead run during the next animation
  frame, but the runloop after the next animation frame. (#365, thanks @Turbo87!)

• Add hashSettled helper for cancellation-aware implementation of RSVP's hashSettled (#353, thanks @kwliou!)

Bugfixes

• Add missing types for linked() and unlinked() (Fixes #373)

Deprecations

• Deprecate direct usage of task with action helper and disable tests for it
  on 3.20+.

  This feature unfortunately depends on private APIs that will be removed in
  Ember 3.25. Unfortunately, the mechanism was already removed in Ember 3.20,
  making it impossible to support this for releases at least until recent
  canaries where it was re-introduced with a deprecation. However, the feature
  is rarely used, only documented in this changelog, and frequently breaks
  whenever the private constant it depends on moves modules internally
  throughout new versions of Ember.

  It will continue to remain available for Ember < 3.20, but will not be
  available in Ember-Concurrency 2.0, and will show a deprecation warning from
  1.3.0 forward.

  Any existing uses can be converted to using {{perform}} directly or
  wrapping the task in (perform) before passing to {{action}} or {{fn}}

  Before:

  <button onClick={{action someTask}}>My button</button>

  After:

  {{!-- Any of these --}}
  <button {{on "click" (perform someTask)}}>My button</button>
  <button onClick={{perform someTask}}>My button</button>
  <button onClick={{action (perform someTask)}}>My button</button>
  <button onClick={{fn (perform someTask)}}>My button</button>
