Versions that are older than the previous two versions are listed in this article and are provided for technical upgrade support only.

+### What's new
+
+- Microsoft Defender Antivirus now caches the Mark of the Web (MoTW) Alternative Data Stream (ADS) for better performance while scanning.
+- Fixed an issue that occurred in [attack surface reduction](attack-surface-reduction-rules-reference.md) in warn mode when removing scan results from the real-time protection cache.
+- Performance improvement added for `OneNote.exe`.
+- Cloud-based entries are regularly removed from the persistent user mode cache in Windows Defender to prevent an uncommon issue where a user could still add a certificate, based on an Indicator of compromise (IoC), to the cache after a file with that certificate had already been added via cloud signature.
+- The Sense onboarding event is now sent in passive mode for operating systems with the old Sense client.
+- Improved performance for logs created/accessed by powershell.
+- Improved performance for folders included in [Controlled folder access(CFA)](controlled-folders.md) when accessing network files.
+- Fixed a deadlock that occurred at shutdown for Data Loss Prevention (DLP) enabled devices.
+- Fixed an issue to remove a vulnerability in the Microsoft Defender Core service.
+- Fixed an onboarding issue in the Unified Agent installation script [install.ps1](https://github.com/microsoft/mdefordownlevelserver).
+- Fixed a memory leak that impacted some devices that received platform update `4.18.24010.7`
