docs(changelog): add release notes for 2.4.2

@angular/language-service now supports using TypeScript 2.1 as the
the TypeScript host. TypeScript 2.1 is now also partially supported
in `ngc` but is not recommended as Tsickle does not yet support 2.1.

+### Note ###
+
+Due to regression in the 2.3.0 release that was fixed by [#13464](https://github.com/angular/angular/pull/13464), 
+components that have been compiled using 2.3.0 and published to npm will need to be recompiled and republished.
+
+The >=2.3.1 compiler will issue is the following error if it encounters components compiled with 2.3.0:  
+`Unsupported metadata version 2 for module ${module}. This module should be compiled with a newer version of ngc`.
+
+We are adding more tests to our test suite to catch these kinds of problems before we cut a release.
