 ### Automation rules now generally available
 
 Automation rules are now generally available (GA) in Microsoft Sentinel.
 
 [Automation rules](automate-incident-handling-with-automation-rules.md) allow users to centrally manage the automation of incident handling. They allow you to assign playbooks to incidents, automate responses for multiple analytics rules at once, automatically tag, assign, or close incidents without the need for playbooks, and control the order of actions that are executed. Automation rules streamline automation use in Microsoft Sentinel and enable you to simplify complex workflows for your incident orchestration processes.

 ### Create a large watchlist from file in Azure Storage (public preview)
 
 Create a watchlist from a large file that's up to 500 MB in size by uploading the file to your Azure Storage account. When you add the watchlist to your workspace, you provide a shared access signature URL. Microsoft Sentinel uses the shared access signature URL to retrieve the watchlist data from Azure Storage.
