Note that the duplication in tsconfig.json files will be fixed in a followup CL now that we have tsconfig inheritance
BREAKING CHANGE: Angular 4 will support only TypeScript 2.1, so we no longer provide backwards compatibility to TS 1.8.
Add upgrade-static.umd.js bundles
This allows depending on it without getting a transitive dependency on compiler.
BREAKING CHANGE:
Four newly added APIs in 2.2.0-beta:
downgradeComponent, downgradeInjectable, UpgradeComponent, and UpgradeModule
are no longer exported by @angular/upgrade.
Import these from @angular/upgrade/static instead.
