⚡ Executive Summary (TL;DR)

TypeScript v3.4.2. Source highlight: This update solely changes TSServer to provide responses to `configurePlugin` requests, and allows global plugins to be loaded by external projects during project creation. This enables TSServer plugins (like IntelliCode) to be used in editors like Visual Studio.
