Answer 1

The AngularJS team announced the end of official support by July 2021. They will release one more version (v1.7) and in July 2018, they will enter a Long Term Support period of 3 years.

During this LTS period they will only apply fixes to v1.7 that are essential for security or browser compatibility, or jQuery changes that would cause production applications to stop working.

After the LTS period, no changes will be made anymore (by Google).

The official announcement can be found in the Angular Blog: Stable AngularJS and Long Term Support.
