BREAKING CHANGE: Because of multiple bugs and browser inconsistencies, we have dropped the intl api in favor of data exported from the Unicode Common Locale Data Repository (CLDR).
Unfortunately we had to change the i18n pipes (date, number, currency, percent) and there are some breaking changes.
1. I18n pipes
* Breaking change:
- By default Angular now only contains locale data for the language `en-US`, if you set the value of `LOCALE_ID` to another locale, you will have to import new locale data for this language because we don't use the intl API anymore.
* Features:
- you don't need to use the intl polyfill for Angular anymore.
- all i18n pipes now have an additional last parameter `locale` which allows you to use a specific locale instead of the one defined in the token `LOCALE_ID` (whose value is `en-US` by default).
- the new locale data extracted from CLDR are now available to developers as well and can be used through an API (which should be especially useful for library authors).
- you can still use the old pipes for now, but their names have been changed and they are no longer included in the `CommonModule`. To use them, you will have to import the `DeprecatedI18NPipesModule` after the `CommonModule` (the order is important):
```ts
import { NgModule } from '@angular/core';
import { CommonModule, DeprecatedI18NPipesModule } from '@angular/common';
@NgModule({
imports: [
CommonModule,
// import deprecated module after
DeprecatedI18NPipesModule
]
})
export class AppModule { }
```
Dont forget that you will still need to import the intl API polyfill if you want to use those deprecated pipes.
2. Date pipe
* Breaking changes:
- the predefined formats (`short`, `shortTime`, `shortDate`, `medium`, ...) now use the patterns given by CLDR (like it was in AngularJS) instead of the ones from the intl API. You might notice some changes, e.g. `shortDate` will be `8/15/17` instead of `8/15/2017` for `en-US`.
- the narrow version of eras is now `GGGGG` instead of `G`, the format `G` is now similar to `GG` and `GGG`.
- the narrow version of months is now `MMMMM` instead of `L`, the format `L` is now the short standalone version of months.
- the narrow version of the week day is now `EEEEE` instead of `E`, the format `E` is now similar to `EE` and `EEE`.
- the timezone `z` will now fallback to `O` and output `GMT+1` instead of the complete zone name (e.g. `Pacific Standard Time`), this is because the quantity of data required to have all the zone names in all of the existing locales is too big.
- the timezone `Z` will now output the ISO8601 basic format, e.g. `+0100`, you should now use `ZZZZ` to get `GMT+01:00`.
| Field type | Format | Example value | v4 | v5 |
|------------|---------------|-----------------------|----|---------------|
| Eras | Narrow | A for AD | G | GGGGG |
| Months | Narrow | S for September | L | MMMMM |
| Week day | Narrow | M for Monday | E | EEEEE |
| Timezone | Long location | Pacific Standard Time | z | Not available |
| Timezone | Long GMT | GMT+01:00 | Z | ZZZZ |
* Features
- new predefined formats `long`, `full`, `longTime`, `fullTime`.
- the format `yyy` is now supported, e.g. the year `52` will be `052` and the year `2017` will be `2017`.
- standalone months are now supported with the formats `L` to `LLLLL`.
- week of the year is now supported with the formats `w` and `ww`, e.g. weeks `5` and `05`.
- week of the month is now supported with the format `W`, e.g. week `3`.
- fractional seconds are now supported with the format `S` to `SSS`.
- day periods for AM/PM now supports additional formats `aa`, `aaa`, `aaaa` and `aaaaa`. The formats `a` to `aaa` are similar, while `aaaa` is the wide version if available (e.g. `ante meridiem` for `am`), or equivalent to `a` otherwise, and `aaaaa` is the narrow version (e.g. `a` for `am`).
- extra day periods are now supported with the formats `b` to `bbbbb` (and `B` to `BBBBB` for the standalone equivalents), e.g. `morning`, `noon`, `afternoon`, ....
- the short non-localized timezones are now available with the format `O` to `OOOO`. The formats `O` to `OOO` will output `GMT+1` while the format `OOOO` will be `GMT+01:00`.
- the ISO8601 basic time zones are now available with the formats `Z` to `ZZZZZ`. The formats `Z` to `ZZZ` will output `+0100`, while the format `ZZZZ` will be `GMT+01:00` and `ZZZZZ` will be `+01:00`.
* Bug fixes
- the date pipe will now work exactly the same across all browsers, which will fix a lot of bugs for safari and IE.
- eras can now be used on their own without the date, e.g. the format `GG` will be `AD` instead of `8 15, 2017 AD`.
3. Currency pipe
* Breaking change:
- the default value for `symbolDisplay` is now `symbol` instead of `code`. This means that by default you will see `$4.99` for `en-US` instead of `USD4.99` previously.
* Deprecation:
- the second parameter of the currency pipe (`symbolDisplay`) is no longer a boolean, it now takes the values `code`, `symbol` or `symbol-narrow`. A boolean value is still valid for now, but it is deprecated and it will print a warning message in the console.
* Features:
- you can now choose between `code`, `symbol` or `symbol-narrow` which gives you access to more options for some currencies (e.g. the canadian dollar with the code `CAD` has the symbol `CA$` and the symbol-narrow `$`).
4. Percent pipe
* Breaking change
- if you don't specify the number of digits to round to, the local format will be used (and it usually rounds numbers to 0 digits, instead of not rounding previously), e.g. `{{ 3.141592 | percent }}` will output `314%` for the locale `en-US` instead of `314.1592%` previously.

Fixes#14417
Updated example to illustrate @ContentChildren default behavior (only query direct children), and how to query for nested elements/all descendants.
DEPRECATION:
- the arguments `inputs` / `outputs` / `ngContentSelectors` of `downgradeComponent`
are no longer used as Angular calculates these automatically now.
- Compiler.getNgContentSelectors is deprecated. Use
ComponentFactory.ngContentSelectors instead.

* feat(common): support `as` syntax in template/* bindings
Closes#15020
Showing the new and the equivalent old syntax.
- `*ngIf="exp as var1”`
=> `*ngIf="exp; let var1 = ngIf”`
- `*ngFor="var item of itemsStream |async as items”`
=> `*ngFor="var item of itemsStream |async; let items = ngForOf”`
* feat(common): convert ngIf to use `*ngIf="exp as local“` syntax
* feat(common): convert ngForOf to use `*ngFor=“let i of exp as local“` syntax
* feat(common): expose NgForOfContext and NgIfContext
