We've created a new Slack notification service for easier management of your Slack notifications. This new notification service requires only a single authorization for the entire workspace and replaces the need for multiple Slack notification services. See the documentation for enabling a Slack Workspace for your organization. Going forward, we recommend using Slack Workspace. Connecting this new notification service will not impact current implementations.

With this change comes:

• Build notifications now include mentions when triggering builds using an account with an associated email in slack workspace.
• Build notifications can be filtered to only trigger on the first failure with started_failing, rather than notifying on recurring failures. Using YAML, this is possible in the existing slack integration and the new workspace.
• Slack channels are now configured in pipeline YAML when using slack workspace.
