* **context:** Context events are now emitted as `ContextEvent` objects
instead of positional arguments. Context listener functions must switch from
the old style to new style as follows:

// ...
});
```

2. New style

```ts
ctx.on('bind', (event: ContextEvent) => {
// ...
});
```

Or:

```ts
ctx.on('bind', ({binding, context, type}) => {
// ...
});
```

* **context:** use Readonly to guard immutable values ([871ddef](https://github.com/strongloop/loopback-next/commit/871ddef))


### BREAKING CHANGES

* **context:** `ctx.get()` and `ctx.getSync()` require a type now.
See the example below for upgrade instructions:

```diff
- const c: MyController = await ctx.get('MyController');
+ const c = await ctx.get<MyController>('MyController');
```

`isPromise` was renamed to `isPromiseLike` and acts as a type guard
for `PromiseLike`, not `Promise`.  When upgrading affected code, you
need to determine whether the code was accepting any Promise
implementation (i.e. `PromiseLike`) or only native Promises. In the
former case, you should use `isPromiseLike` and potentially convert the
userland Promise instance to a native Promise via
`Promise.resolve(promiseLike)`. In the latter case, you can replace
`isPromise(p)` with `p instanceof Promise`.

### BREAKING CHANGES

* **context:** It is no longer possible to pass a promise instance
to `.to()` method of a Binding. Use `.toDynamicValue()` instead.
Consider deferring the async computation (that produced the promise
instance you are binding) into the dynamic value getter function,
i.e. start the async computation only from the getter function.

An example diff showing how to upgrade your existing code:

-    ctx.bind('bar').to(Promise.resolve('BAR'));
+    ctx.bind('bar').toDynamicValue(() => Promise.resolve('BAR'));
