Some notable features of this version include: template binding syntax improvements, TypeScript 2.1 and 2.2 compatibility, and source maps for temples.

Going forward, developers can expect patch updates and ongoing work on version 4.1. The team is still creating a roadmap for the next six months. According to its release schedule, version 5.0 is expected in the fall of 2017 with version 6.0 being released March of 2018.

Angular 4 Beta 5 version is released. Check out the new changes from here

The beta phase officially began in mid-December 2016 and has rapidly gone through six beta versions (beta.5 was released on January 25)

The sixth beta version consists of 11 bug fixes and eight new features. 

Angular 4 Beta 1 was released in December. Angular JS Development Company.

In November 2016, Google surprised everyone when it detailed plans for Angular 3 to be released a short six months after Angular 2’s arrival. Now it turns out there will be “No Angular 3“ release after all. Instead, “Google will go right to version 4“ of its popular JavaScript framework in March 2017.features and release date

Google’s Igor Minar said at the recent NG-BE 2016 Angular conference in Belgium that Google will jump from version 2 to version 4 so that the number of the upgrade correlates with the Angular version 4 router planned for usage with the release.

Minar, in fact, laid out a road map that has eight beta releases of Angular 4 coming out between December and February, followed by two release candidates in February and the general release on March 1. But Minar cautioned against getting too hung up on numbers and advised that the framework simply is called “Angular” anyway. “Let’s not call it Angular JS development services, let’s not call it Angular 2,” he said, “because as we are releasing more and more of these versions, it’s going to be super-confusing for everybody.” 

Tentative Angular 4 release schedule

The fact that breaking changes will arrive, doesn’t mean they will arrive every other week. The Angular team committed to time-based releases that occur in three cycles:

    — patch releases every week,
    — 3 monthly minor release after each major release and
    — a major release with easy-to-migrate-over breaking changes every 6 months.

Angular is on an aggressive schedule that would have Angular 5 arriving in September/October 2017, followed by six months by Angular 6, with Angular 7 coming six months later in September/October 2018. The next 3 months will be dedicated to finalizing Angular 4.0.0. Angular 4 features and release date

Google’s goals for Angular 4 are to be as backward-compatible with Angular 2 as possible and to improve compiler error messages. In November, Google talked about the next version of Angular, then known as version 3, emphasizing improvements in tooling as well as reduced code generation.

Angular’s upgrade plan also includes moving to TypeScript 2.1 as a baseline, away from TypeScript 1.8. While this means there are breaking changes, Minar was reassuring. “It’s not going to be a big deal. 

We did these migrations across the whole Google and it was quite trivial, but it does require [some interventions].” Angular 2 was rewritten in TypeScript, Microsoft’s typed superset of JavaScript.

Earlier this month, Google earlier this month released Angular 2.3, a minor upgrade featuring Angular Language Service, which is designed to integrate with IDEs and provide type completion and error-checking with Angular Templates.

Object inheritance for components is featured as well. Angular 2.2 arrived in November, featuring ahead-of-time compilation compatibility.
