Ivy Everywhere

Angular 12 is the step in the Angular revolution.

  • Current libraries with View Engine will continue to function with Ivy apps. However, with Angular 12 it is about time that library authors start planning to transition to Ivy.

Migrating from legacy i18n message IDs

Legacy message-ids come across with issues relating to whitespace and the organizing formats and ICU expressions utilized in the i18n framework. In order to overcome this matter, the Angular team is making the standard message-id design stronger and better. This configuration will reduce the superfluous translation invalidation as well as related retranslation cost in applications where translations don’t organize due to whitespace changes.

Since Angular version 11, new tasks leverage new message ids and they presently have the tooling to move existing ventures with existing translations. Angular 12 provides essential tools to migrate the translations.

Adios Protractor

Angular syncs well with tools such as Cypress, WebdriverIO, and TestCafe. The future of Protractor seemed in doubt. However, moving forward Protractor will not be included in Angular projects. While the team is reviewing feedback, more news on the fate of Protractor is expected soon, probably in the next update.
