This major release bumps dependencies to their latest versions and sets the minimum node version is to v18, the current LTS node.js. While the library should work with older versions of node, we no longer test the library against versions of node older than 18, so we cannot guarantee compatibility.
In addition, calling disconnect() when already disconnected should no longer throw an exception (fixed https://github.com/slackapi/node-slack-sdk/issues/842).
