Angular (commonly referred to as "Angular 2+" or "Angular v2 and above") is a TypeScript-based open-source web application framework 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.
|Initial release||2.0 / 14 September 2016|
7.2.12 / 4 April 2019
8.0.0-beta.11 / 4 April 2019
Angular was a ground-up rewrite of AngularJS.

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.
Angular 2.0 was announced at the ng-Europe conference 22-23. October 2014. The drastic changes in the 2.0 version created considerable controversy among developers. On April 30, 2015, the Angular developers announced that Angular 2 moved from Alpha to Developer Preview. Angular 2 moved to Beta in December 2015, and the first release candidate was published in May 2016. The final version was released on September 14, 2016.
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. The final version was released on March 23, 2017. Angular 4 is backward compatible with Angular 2.
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
Angular 6 was released on May 4, 2018.. 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.
Angular 7 was released on October 18, 2018. Updates regarding Application Performance, Angular Material & CDK, Virtual Scrolling, Improved Accessibility of Selects, now supports Content Projection using web standard for custom elements, and dependency updates regarding Typescript 3.1, RxJS 6.3, Node 10 (still supporting Node 8).
One of the highlights is the expected release of Ivy, a backwards compatible, completely new render engine based on the incremental DOM architecture. Ivy has been engineered with tree shaking in mind, which means that application bundles will only include the parts of Angular source code that is actually used by the application.
Each version is expected to be backward-compatible with the prior release. Google pledged to do twice-a-year upgrades.
All the major releases are supported for 18 months. This consists of 6 months of active support, during which regularly-scheduled updates and patches are released. It is then followed by 12 months of long-term support (LTS), during which only critical fixes and security patches are released.
