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
- compiler: The method
ngGetContentSelectors()
, deprecated in Angular 4.0, has been removed. UseComponentFactory.ngContentSelectors
instead. -
- the Angular compiler now requires TypeScript 2.4.x.
- router:
RouterOutlet
propertieslocationInjector
andlocationFactoryResolver
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 optionenableLegacyTemplate
and the<template>
element will both be removed in Angular v6. - core:
OpaqueToken
has been removed as it was deprecated since v4. UseInjectionToken
instead. platformXXXX()
no longer accepts providers which depend on reflection. Specifically the method signature when fromProvider[]
toStaticProvider[]
.
Example: Before:
1 2 3 4 5 6 |
[ MyClass, {provide: ClassA, useClass: SubClassA} ] |
After:
1 2 3 4 5 |
[ {provide: MyClass, deps: [Dep1,...]}, {provide: ClassA, useClass: SubClassA, deps: [Dep1,...]} ] |
NOTE: This only applies to platform creation and providers for the JIT compiler. It does not apply to @Component
or @NgModule
provides 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 ofLOCALE_ID
to another locale, you will have to import new locale data for this language because we don't use the intl API anymore.
- By default Angular now only contains locale data for the language
- 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 tokenLOCALE_ID
(whose default value isen-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 theDeprecatedI18NPipesModule
after theCommonModule
(the order is important):
1234567891011<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 be8/15/17
instead of8/15/2017
foren-US
. - the narrow version of eras is now
GGGGG
instead ofG
, the formatG
is now similar toGG
andGGG
. - the narrow version of months is now
MMMMM
instead ofL
, the formatL
is now the short standalone version of months. - the narrow version of the week day is now
EEEEE
instead ofE
, the formatE
is now similar toEE
andEEE
. - the timezone
z
will now fallback toO
and outputGMT+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 useZZZZ
to getGMT+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 - the predefined formats (

- new predefined formats
long
,full
,longTime
,fullTime
. - the format
yyy
is now supported, e.g. the year52
will be052
and the year2017
will be2017
. - standalone months are now supported with the formats
L
toLLLLL
. - week of the year is now supported with the formats
w
andww
, e.g. weeks5
and05
. - week of the month is now supported with the format
W
, e.g. week3
. - fractional seconds are now supported with the format
S
toSSS
. - day periods for AM/PM now supports additional formats
aa
,aaa
,aaaa
andaaaaa
. The formatsa
toaaa
are similar, whileaaaa
is the wide version if available (e.g.ante meridiem
foram
), or equivalent toa
otherwise, andaaaaa
is the narrow version (e.g.a
foram
). - extra day periods are now supported with the formats
b
tobbbbb
(andB
toBBBBB
for the standalone equivalents), e.g.morning
,noon
,afternoon
, .... - the short non-localized timezones are now available with the format
O
toOOOO
. The formatsO
toOOO
will outputGMT+1
while the formatOOOO
will beGMT+01:00
. - the ISO8601 basic time zones are now available with the formats
Z
toZZZZZ
. The formatsZ
toZZZ
will output+0100
, while the formatZZZZ
will beGMT+01:00
andZZZZZ
will be+01:00
.
- new predefined formats
- 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 beAD
instead of8 15, 2017 AD
.
Currency pipe
- Breaking change:
- the default value for
symbolDisplay
is nowsymbol
instead ofcode
. This means that by default you will see$4.99
foren-US
instead ofUSD4.99
previously.
- the default value for
- Deprecation:
- the second parameter of the currency pipe (
symbolDisplay
) is no longer a boolean, it now takes the valuescode
,symbol
orsymbol-narrow
. A boolean value is still valid for now, but it is deprecated and it will print a warning message in the console.
- the second parameter of the currency pipe (
- Features:
- you can now choose between
code
,symbol
orsymbol-narrow
which gives you access to more options for some currencies (e.g. the canadian dollar with the codeCAD
has the symbolCA$
and the symbol-narrow$
).
- you can now choose between
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 output314%
for the localeen-US
instead of314.1592%
previously.
- 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.
