 ## December 2024
 
-- If you're using Microsoft's unified security operations (SecOps) platform, with both Microsoft Sentinel and Microsoft Defender XDR, Microsoft Sentinel workbooks are now available to view directly in the Microsoft Defender portal. Continue tabbing out to the Azure portal only to edit your workbooks. For more information, see [Visualize and monitor your data by using workbooks in Microsoft Sentinel](/azure/sentinel/monitor-your-data?tabs=azure-portal).
 - (Preview) The [Link to incident](advanced-hunting-defender-results.md#link-query-results-to-an-incident) feature in Microsoft Defender advanced hunting now allows linking of Microsoft Sentinel query results. In both the Microsoft Defender unified experience and in [Defender XDR advanced hunting](advanced-hunting-link-to-incident.md), you can now specify whether an entity is an impacted asset or related evidence.
 - (Preview) In [advanced hunting](advanced-hunting-defender-use-custom-rules.md#use-adx-operator-for-azure-data-explorer-queries-preview), Microsoft Defender portal users can now use the `adx()` operator to query tables stored in Azure Data Explorer. You no longer need to go to log analytics in Microsoft Sentinel to use this operator if you are already in Microsoft Defender.
