2.3.0 - async arrow fn tasks

NOTE: v2.3.2 simplifies the new task() API even more further; you should upgrade to that (or higher!)

2.3.0

• Introduce async-arrow task() API as the new universal JS/TS API, e.g.
  myTask = task(this, { drop: true }, async (arg: string) => {}). This new API
  sidesteps the vast majority of TypeScript issues that plagued past decorators- and generators-
  based APIs. All prior APIs are still supported, but users are strongly recommended
  to migrate to the new API. Recommended steps:
  • Finish migrating any classes with EC tasks to ES6 class syntax
  • Once you've done that, use the following codemods
    • Convert @task decorator based APIs to the new async-arrow fn
      • npx machty-ember-concurrency-codemods async-arrow-task app/**/*.ts app/**/*.js
    • If you've used ember-concurrency-ts, run the following codemod to remove taskFor()
      • npx machty-ember-concurrency-codemods rm-ember-concurrency-ts app/**/*.ts app/**/*.js
• The ember-concurrency-ts and ember-concurrency-async packages are no longer needed
  and can be removed
• Soft-deprecated (removed from documentation, likely to formally deprecate later)
  a number of less commonly used features
  • Encapsulated Tasks
  • Task Groups

2.2.1

Bugfixes

• Added missing TypeScript types for onState task modifier and
  TaskFactory#setOnState (#449, fixed #447. Thanks @johanrd for the heads up!)

2.2.0

New Features

• Implemented a public API for Task Modifiers,
  providing a way for users to define additional modifiers and behavior in
  application code. (#441) Please consider the TaskProperty
  prototype extension method of implementing task modifiers to be deprecated
  in favor of the registerModifier API.
• Add onError parameter to perform helper to allow UI-triggered tasks to
  specify alternative or null error handlers (#443, fixes #435. Thanks
  @lolmaus for the discussion)

Bugfixes

• Fix inefficent use of run.once (#442, fixes #437. Thanks @stefanpenner for
  the heads up!)

2.1.2

Bugfixes

• Expose TaskInstance state inside encapsulated tasks (#434)

Misc

• [dev] use prettier to format code (#415, thanks @alexlafroscia!)
• [dev] test against embroider scenarios (#430, thanks @alexlafroscia!)

2.1.0

New Features

• Implemented a public API for Yieldables, a new way to instrument TaskInstances by providing a safe mechanism to implement custom waiters, hooks, introspection, and other operations from application code. (#413)

Read more about Yieldables in the ember-concurrency docs

Bugfixes

• Avoid applying task state updates out of order (#423, #426, fixes #422)

Docs

• [docs] Document that @lastValue does not support chained property access (#429)

2.0.3

Bugfixes

• Remove runloop binding for perform and cancel-all helpers, which prevented proper instrumentation. (#414, fixes #409)
• Fix incorrect import for deprecated private task-instance module alias (#411, thanks @mydea!)

Misc

• [dev] Upgrade qunit to v5 (#410, thanks @alexlafroscia)
• [docs] Fix missing jsdoc documentation (#407)

2.0.2

Bugfixes

• Ensure lastRunning resets one-by-one as tasks are completed, successfully
  or not. (Fixes #403)
• Expose lastValue decorator in TS definitions (Fixes #404)

2.0.1

Bugfixes

• Prevent synchronous errors in cancelable promise helpers from being rethrown asynchronously later (#402, fixes #400. thanks @Turbo87 for flagging!)
• Restore access to host context from encapsulated tasks (#401)

2.0.0

ember-concurrency 2.0 is primarily an "engine" replacement. Internally, its been substantially rewritten and decoupled from Ember at it's core. This will enable a much more maintainable codebase, as well as setting the stage for potential extraction of core primatives for us in the broader JavaScript ecosystem.

The application developer-facing changes are fairly minimal, and there are few potentially breaking semantic changes to the operation of the addon.

Please review the 2.0 Upgrade Guide for a thorough description of the changes for app and addon users alike.

New Features

• 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.

• Implement decorators from ember-concurrency-decorators. 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.

  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.

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

• [docs] 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.

• Make Task#cancelAll and TaskInstance#cancel awaitable (#396). See
  topic in UPGRADING-2.x.md for more info.

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.

• 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.

2.0.0-rc.2

Enhancements

• Make Task#cancelAll and TaskInstance#cancel awaitable (#396). See
  topic in UPGRADING-2.x.md for more info.

Bugfixes

• Fix TaskProperty extension methods not working with built-in decorators
  (e.g. ember-concurrency-retryable, ember-concurrency-test-waiters, etc.)

Misc.

• [dev] Add test for interop w/ ember-concurrency-decorators
• [dev] Migrate CI to GitHub Actions (#393)
