Ember CLI Deploy Slack Plugin

ember-cli-deploy-slack is an ember-cli-deploy plugin designed to send deployment notifications to Slack. It integrates deeply into the `ember-cli-deploy` pipeline, providing hooks to send customizable messages for various stages such as `didDeploy` and `didFail`. The current stable version is 2.0.0, which includes updated dependencies and Node.js version requirements. As an Ember CLI Deploy plugin, its release cadence is typically aligned with the broader Ember ecosystem and major dependency updates. Its key differentiator is its seamless integration with the `ember-cli-deploy` context, allowing dynamic message generation using deployment-specific data, and leveraging `node-slackr` for flexible Slack message formatting.
