- a full MV* implementation - routing - DI - decorators - CSP / XSS protection - a ton of services for mocking for unit tests ($http, $window, et al)

I'm sure I'm missing a fair amount of stuff here, too. This is just what I get out of Angular 1.x on a daily basis.

* More mature router (IMHO, the best router out of all JS frameworks) * A CLI for developers to generate their models, views, components, controllers, routes * An opinion on where things should live and how they should be structured (ups the learning curve but saves time in the seemingly endless developer debates when discussing architecture)
