This release is meant to help users migrate to the smaller, lighter,
independent packages. If you'd just like to test the compatibility of
your app with the latest breaking changes, you can simply update the
from a previous version of this package to this version. If everything
works, you're ready to change your code to depend on the independent
packages instead.

For each of the follow classes, these packages should be used directly.

| Class name        | Command to install           |
|-------------------|------------------------------|
| `WebClient`       | `npm install @&#8203;slack/web-api` |
| `RTMClient`       | `npm install @&#8203;slack/rtm-api` |
| `IncomingWebhook` | `npm install @&#8203;slack/webhook` |

See the [migration
guide](https://slack.dev/node-slack-sdk/tutorials/migrating-to-v5) for
more details.
