Angular 5.0.0 Final Release "Pentagonal Donut" disponibile per il download su GitHub!

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…

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  , if you set the value of   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   which allows you to use a specific locale instead of the one defined in the token   (whose default value is  ).
    • 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  . To use them, you will have to import the   after the   (the order is important):

    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 ( , …) 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.   will be  instead of   for  .
    • the narrow version of eras is now   instead of  , the format   is now similar to   and  .
    • the narrow version of months is now   instead of  , the format   is now the short standalone version of months.
    • the narrow version of the week day is now   instead of  , the format   is now similar to   and  .
    • the timezone   will now fallback to   and output   instead of the complete zone name (e.g.  ), 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   will now output the ISO8601 basic format, e.g.  , you should now use   to get  .
    Field typeFormatExample valuev4v5
    ErasNarrowA for ADGGGGGG
    MonthsNarrowS for SeptemberLMMMMM
    Week dayNarrowM for MondayEEEEEE
    TimezoneLong locationPacific Standard TimezNot available
    TimezoneLong GMTGMT+01:00ZZZZZ
  • Features
    • new predefined formats  .
    • the format   is now supported, e.g. the year   will be   and the year   will be  .
    • standalone months are now supported with the formats   to  .
    • week of the year is now supported with the formats   and  , e.g. weeks   and  .
    • week of the month is now supported with the format  , e.g. week  .
    • fractional seconds are now supported with the format   to  .
    • day periods for AM/PM now supports additional formats   and  . The formats   to   are similar, while   is the wide version if available (e.g.   for  ), or equivalent to   otherwise, and   is the narrow version (e.g.   for  ).
    • extra day periods are now supported with the formats   to   (and   to   for the standalone equivalents), e.g.  , ….
    • the short non-localized timezones are now available with the format   to  . The formats   to   will output   while the format   will be  .
    • the ISO8601 basic time zones are now available with the formats   to  . The formats   to   will output  , while the format   will be   and   will be  .
  • 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   will be   instead of  .
Currency pipe
  • Breaking change:
    • the default value for   is now   instead of  . This means that by default you will see  for   instead of   previously.
  • Deprecation:
    • the second parameter of the currency pipe ( ) is no longer a boolean, it now takes the values   or  . 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   or   which gives you access to more options for some currencies (e.g. the canadian dollar with the code   has the symbol   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.   will output   for the locale  instead of   previously.
