One of the biggest worries was about how long Google was going to support version 1.X. To allay these fears,Google has taken a new approach to determining where the community is at and what they want. The Angular 1.X project will continue to be hosted at angularjs.org. Angular 2.0,now in Alpha,will be hosted at angular.io.
The team will look at the traffic to both sites,along with GitHub,in order to determine where the community is still invested. This means that if a majority of traffic is still at angularjs.org,the team will continue to focus resources on 1.X. Angular 1.X will not end life until the majority of traffic has moved to 2.0. “We’ll continue releasing Angular 1 releases until the vast majority of you migrate to Angular 2,” said Minar.
上述报价是从2015年3月。一个more recent quote从2015年10月说：
We at Google are actually going to be on Angular 1 for some time,even though we’ve started to adopt Angular 2 internally,” Green said,speaking about Google’s own Angular-based projects.

我找不到一个官方公告，当安全补丁和错误修复将不再被开发。最近我发现是从2014年10月，可能不再相关：
According to Brad Green of Angular,Angular 1.3 will continue to receive bugfix and security patch support for 18-24 months after the release of version 2.0.
虽然我的意见不是官方的，我期望开发商社区将叉Angular 1.x并继续保持它多年。有太多的大型应用程序写在Angular1.x的顶部，只是放弃一切，冲破了Angular2。
