2.0.0-rc.1

New features

• Implement decorators from ember-concurrency-decorators (#386). The "nice" decorators
  from ember-concurrency-decorators are now built-in to ember-concurrency, without
  requiring an additional addon or seperate import. All decorators are available for
  import directly from the top-level ember-concurrency package.

  Many thanks to @buschtoens for years of stewardship of that addon, and important contributions from @chancancode for TypeScript support, and others in the community to get it to a place where it's seen wide adoption in the world of Ember Octane, TypeScript, and native ES classes.

  Addon maintainers: Please see notes in UPGRADING-2.x.md if you're using
  decorators currently, and wish to support both ember-concurrency 1.x and 2.x at
  runtime.

Documentation

• Rewrite documentation to use native classes and decorators, and update tutorial
  to show rewriting of async function code, rather than Promise code, as is more common
  today (#387, #389)

2.0.0-beta.2

Enhancements

• Migrate task lifetimes to @ember/destroyable underneath, rather than
  patching willDestroy (#377).

  Potentially breaking: this drops support for Node 8 and Ember < 3.8 LTS

Bugfixes

• Ensure encapsulated task state can be accessed on the TaskInstance (#381, #383)

  Note: this uses Proxy and WeakMap, which may need to be polyfilled/unavailable on
  older browsers.

• Make sure task/group-level state field is tracked (#382)

Removals

• Drop unused broccoli-file-creator and ember-maybe-import-regenerator
  dependencies.

  Note on ember-maybe-import-regenerator: This was originally added back when
  generator support in browsers was far lower and Babel 5 and 6 were used. The
  addon does nothing for Babel 7, which is used for ember-concurrency these
  days. Tweaking config/targets.js or adding the regenerator Babel plugin to
  your babel config can be done instead if the regenerator runtime is needed
  to transpile generators for older browsers.

Other

• [dev] Upgrade Ember-CLI to 3.22 (#380)

2.0.0-beta.1

Enhancements

• Port over changes from 1.1.6 through 1.3.0 (#367)

• Use @tracked underneath on Ember 3.16+ (#354)

  Note: Within applications with both tracked & computed properties,
  if using a native getter to access task state, and wishing to use it
  alongside a computed property, @dependantKeyCompat will need to be used on
  the getter as expected with any other tracked-prop using getter.

Bugfixes

• Fixes the deprecated -task-property module (for compatibility w/ some
  external addons). TaskProperty is available at the top-level.

Removals

• Remove ability to directly use tasks with {{action}} helper stuff
  (deprecated in 1.3.0) (#374)
• Remove get and set compatibility methods from Task, TaskGroup,
  and TaskInstance.

Documentation about upgrading to 2.0.0-beta.1 and other future 2.x releases in
general can be found in UPGRADING-2.x.md

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>

1.2.1

Bugfixes

• Correct types for encapsulated tasks to allow accessing encapsulated task state (#362, thanks @chancancode!)
• Correct types to reflect that Task, TaskInstance, and TaskGroup extend EmberObject (#363, thanks @jamescdavis!)

1.2.0

New Features

• Introduce official TypeScript definitions targeting the last 3 versions of
  TypeScript. A big, big thank you to @chancancode for this heroic effort!
  Also, a thank you to all others before who worked on previous iterations of
  typing experiments for ember-concurrency and provided feedback. If you were
  using one of the community-provided solutions or other custom type definitions,
  you will likely need to remove those and refactor to adhere to the new official
  types. (#357)

  For more information about using TypeScript with ember-concurrency, please see the new docs page

1.1.7

Bugfixes

• Fix waitForProperty on non-EmberObject hosts (i.e. native classes) (#352. Fixes #292. Thanks @andrewfan for the find!)

1.1.6

Enhancements

• Add support for waitForEvent helper on host objects supporting 'on' API. Previously, waitForEvent only supported DOM-like objects with addEventListener/removeEventListener or jQuery-like objects with one/off, but did not support those with just on/off. (#348. Fixes #164)

2.0.0-alpha.0

Breaking Changes

• Currently, there are no known breaking changes related to user-facing APIs. Paths to various private modules have changed, so if you were depending on those, they may need to be updated. Please open an issue and let us know what you're using them for.

Enhancements

• @machty refactored & cleaned up the scheduler and core to rely less on computed properties, and potentially make the core extractable and usable in non-Ember environments. (#302)

Bugfixes

• Fixes derived state related bugs (#175, #278, potentially more)

Notes

• This is a pre-release, so we don't necessarily recommend its use in production, but would love your feedback.
• There may be breaking changes in future 2.0.0 pre-releases.

1.1.5

Bugfixes

• Avoid auto-tracking rerender assertion / infinite rerender during cancellation in certain contexts in Ember 3.15+ (#341, Fixes #340)
