### BREAKING CHANGES

- **zone.js:** in TaskTrackingZoneSpec track a periodic task until it is cancelled

The breaking change is scoped only to the plugin
`zone.js/plugins/task-tracking`. If you used `TaskTrackingZoneSpec` and
checked the pending macroTasks e.g. using `(this.ngZone as any)._inner ._parent._properties.TaskTrackingZone.getTasksFor('macroTask')`, then
its behavior slightly changed for periodic macrotasks. For example,
previously the `setInterval` macrotask was no longer tracked after its
callback was executed for the first time. Now it's tracked until
the task is explicitly cancelled, e.g with `clearInterval(id)`.

### BREAKING CHANGES

- **zone.js:** ZoneJS no longer swallows errors produced by `Object.defineProperty` calls.

Prior to this change, ZoneJS monkey patched `Object.defineProperty` and if there is an error
(such as the property is not configurable or not writable) the patched logic swallowed it
and only console.log was produced. This behavior used to hide real errors,
so the logic is now updated to trigger original errors (if any). One exception
where the patch remains in place is `document.registerElement`
(to allow smooth transition for code/polyfills that rely on old behavior in legacy browsers).
If your code relies on the old behavior (where errors were not thrown before),
you may need to update the logic to handle the errors that are no longer masked by ZoneJS patch.

## [0.11.1](https://github.com/angular/angular/compare/zone.js-0.11.0...zone.js-0.11.1) (2020-08-19)

### Bug Fixes

- **zone.js:** zone.js package.json should not include files/directories field ([#38528](https://github.com/angular/angular/issues/38528)) ([6b662d1](https://github.com/angular/angular/commit/6b662d1)), closes [#38526](https://github.com/angular/angular/issues/38526) [#38516](https://github.com/angular/angular/issues/38516) [#38513](https://github.com/angular/angular/issues/38513)

# BREAKING CHANGES since Zone.js v0.11.1

Prior to `v0.11.1`, Zone.js provided two distribution bundle formats in the `dist` folder.
They were (1) `ES5` bundle distributed as `zone.js` and (2) `ES2015` bundle distributed as `zone-evergreen.js`.
These bundles are used for Angular's differential-loading mechanism.

Prior to `v0.11.11` the following code

```
import 'zone.js';
```

would load the `ES5` bundle from `dist/zone.js`.

Starting with `v0.11.1`, Zone.js follows the [Angular Package Format](https://docs.google.com/document/d/1CZC2rcpxffTDfRDs6p1cfbmKNLA6x5O-NtkJglDaBVs), so the folder structure of the Zone.js bundles is updated to match `Angular Package Format`.
So the same code

```
import 'zone.js';
```

now loads the `ES2015` bundle instead.

This is a breaking change for legacy browsers such as `IE11`.

For backwards compatibility `zone.js` continues to distribute the same bundles under `dist`.
To restore the old behavior change the `polyfills.ts` generated by `Angular CLI` to import like so:

```
import 'zone.js/dist/zone';
```

- minor fixes ([18f5511](https://github.com/angular/zone.js/commit/18f5511))

### Code Refactoring

- split zone.js into CJS modules, add zone-microtask.js ([2e52900](https://github.com/angular/zone.js/commit/2e52900))

### Features

- **scheduling:** Prefer MutationObserver over Promise in FF ([038bdd9](https://github.com/angular/zone.js/commit/038bdd9))
- **scheduling:** Support Promise.then() fallbacks to enqueue a microtask ([74eff1c](https://github.com/angular/zone.js/commit/74eff1c))
- add isRootZone api ([bf925bf](https://github.com/angular/zone.js/commit/bf925bf))
- make root zone id to be 1 ([605e213](https://github.com/angular/zone.js/commit/605e213))

### BREAKING CHANGES

- New child zones are now created only from a async task
  that installed a custom zone.

Previously even without a custom zone installed (e.g.
LongStacktracesZone), we would spawn new
child zones for all asynchronous events. This is undesirable and
generally not useful.

It does not make sense for us to create new zones for callbacks from the
root zone since we care
only about callbacks from installed custom zones. This reduces the
overhead of zones.

This primarily means that LongStackTraces zone won't be able to trace
events back to Zone.init(),
but instead the starting point will be the installation of the
LongStacktracesZone. In all practical
situations this should be sufficient.

- zone.js as well as \*-zone.js files are moved from / to dist/
