Angular (commonly referred to as "Angular 2+" or "Angular v2 and above")[4][5] is a TypeScript-based open-source front-end web application platform led by the Angular Team at Google and by a community of individuals and corporations. Angular is a complete rewrite from the same team that built AngularJS.

Differences between Angular and AngularJS

Architecture of an Angular application. The main building blocks are modules, components, templates, metadata, data binding, directives, services and dependency injection.

Angular was a ground-up rewrite of AngularJS.

History

Naming

Originally, the rewrite of AngularJS was called "Angular 2" by the team, but this led to confusion among developers. To clarify, the team announced that separate terms should be used for each framework with "AngularJS" referring to the 1.X versions and "Angular" without the "JS" referring to versions 2 and up.[8]

Version 2.0.0

Angular 2.0 was announced at the ng-Europe conference 22-23. October 2014.[9][10] The drastic changes in the 2.0 version created considerable controversy among developers.[11] On April 30, 2015, the Angular developers announced that Angular 2 moved from Alpha to Developer Preview.[12] Angular 2 moved to Beta in December 2015,[13] and the first release candidate was published in May 2016.[14] The final version was released on September 14, 2016.

Version 4.0.0

On 13 December 2016 Angular 4 was announced, skipping 3 to avoid a confusion due to the misalignment of the router package's version which was already distributed as v3.3.0.[15] The final version was released on March 23, 2017.[16] Angular 4 is backward compatible with Angular 2.[17]

Angular version 4.3 is a minor release, meaning that it contains no breaking changes and that it is a drop-in replacement for 4.x.x.

Features in version 4.3

  • Introducing HttpClient, a smaller, easier to use, and more powerful library for making HTTP Requests.
  • New router life cycle events for Guards and Resolvers. Four new events: GuardsCheckStart, GuardsCheckEnd, ResolveStart, ResolveEnd join the existing set of life cycle event such as NavigationStart.
  • Conditionally disable animations.

Version 5.0.0

Angular 5 was released on November 1, 2017.[18] Key improvements in Angular 5 include support for progressive web apps, a build optimizer and improvements related to Material Design.[19]

Version 6.0.0

Angular 6 was released on May 4, 2018.[20]. This is a major release focused less on the underlying framework, and more on the toolchain and on making it easier to move quickly with Angular in the future, like: ng update, ng add, Angular Elements, Angular Material + CDK Components, Angular Material Starter Components, CLI Workspaces, Library Support, Tree Shakable Providers, Animations Performance Improvements, and RxJS v6.

Future releases

Angular 7 release will be showing up in September or October 2018. Each version is expected to be backward-compatible with the prior release. Google pledged to do twice-a-year upgrades.
