E' stata dura, ma ce l'hanno fatta: dopo nove release candidate che si sono succedute in poco meno di un mese e mezzo, la Final Release di Angular 5.0.0, nota da oggi come Pentagonal Donut, è finalmente uscita! La nuova versione porta con sé una serie di nuove funzionalità, miglioramenti prestazionali e (ahimé) cambiamenti non retro-compatibili al codice rispetto alla precedente v4: siamo certi che non mancheremo di amarla, specialmente dopo questa estenuante attesa!

Ecco il changelog cumulativo della nuova versione 5.x aggiornato ad oggi, giorno della pubblicazione di Angular 5.0.0 final sul GitHub ufficiale del progetto. Per informazioni aggiuntive sulle Release Candidate precedenti, potete dare un'occhiata a questo articolo (dalla RC0 alla RC7), a questo articolo (per la RC8) e infine a questo articolo (per la RC9).

Cos'altro è rimasto da dire? Probabilmente nulla, a parte forse un paio di parole in maiuscolo...

... ERA ORA !

:)

BREAKING CHANGES

• • the Angular compiler now requires TypeScript 2.4.x.
• router: RouterOutlet properties locationInjector and locationFactoryResolver have been removed as they were deprecated since v4.
• compiler: the compiler option enableLegacyTemplate is now disabled by default as the <template> element has been deprecated since v4. Use <ng-template> instead. The option enableLegacyTemplate and the <template> element will both be removed in Angular v6.
• core: OpaqueToken has been removed as it was deprecated since v4. Use InjectionToken instead.
• platformXXXX() no longer accepts providers which depend on reflection. Specifically the method signature when from Provider[] to StaticProvider[].

Example: Before:

After:

NOTE: This only applies to platform creation and providers for the JIT compiler. It does not apply to @Component or @NgModuleprovides declarations.

Benchpress note: Previously Benchpress also supported reflective provides, which now require static providers.

I18n Changes (@angular/common)

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.

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 default value is en-US).
  • 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):
  <span class="pl-k">import</span> { <span class="pl-smi">NgModule</span> } <span class="pl-k">from</span> <span class="pl-s"><span class="pl-pds">'</span>@angular/core<span class="pl-pds">'</span></span>; <span class="pl-k">import</span> { <span class="pl-smi">CommonModule</span>, <span class="pl-smi">DeprecatedI18NPipesModule</span> } <span class="pl-k">from</span> <span class="pl-s"><span class="pl-pds">'</span>@angular/common<span class="pl-pds">'</span></span>; @<span class="pl-en">NgModule</span>({ imports: [ <span class="pl-smi">CommonModule</span>, <span class="pl-c">// import deprecated module after</span> <span class="pl-smi">DeprecatedI18NPipesModule</span> ] }) <span class="pl-k">export</span> <span class="pl-k">class</span> <span class="pl-en">AppModule</span> { }

  1 2 3 4 5 6 7 8 9 10 11

  <span class="pl-k">import</span> { <span class="pl-smi">NgModule</span> } <span class="pl-k">from</span> <span class="pl-s"><span class="pl-pds">'</span>@angular/core<span class="pl-pds">'</span></span>; <span class="pl-k">import</span> { <span class="pl-smi">CommonModule</span>, <span class="pl-smi">DeprecatedI18NPipesModule</span> } <span class="pl-k">from</span> <span class="pl-s"><span class="pl-pds">'</span>@angular/common<span class="pl-pds">'</span></span>;   @<span class="pl-en">NgModule</span>({   imports: [     <span class="pl-smi">CommonModule</span>,     <span class="pl-c">// import deprecated module after</span>     <span class="pl-smi">DeprecatedI18NPipesModule</span>   ] }) <span class="pl-k">export</span> <span class="pl-k">class</span> <span class="pl-en">AppModule</span> { }

  Don't forget that you will still need to import the intl API polyfill if you want to use those deprecated pipes.

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 8/15/17instead 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.

Currency pipe

• Breaking change:
  • the default value for symbolDisplay is now symbol instead of code. This means that by default you will see $4.99for 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 $).

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-USinstead of 314.1592% previously.
