Defender ATP version 10.8775

Were you looking for anything specific about this? as I see you're right that for example this has not been updated with the latest version information

https://learn.microsoft.com/en-us/defender-endpoint/whats-new-in-microsoft-defender-endpoint

However Sense gets updated often with the monthly updates and here you can see this versioning by going to, say the latest December cumulative patch information here is an example. go to the the Windows update catalog and get the latest CU update version and got to more information

Go to the File information

This will download the list of files in Cumulative update

In for example my laptop

This matches the Defender console output for versions distributed

You might say I'm being obvious, and if that's the case yes seems like MS may need to update the Version history docs but not sure if they do this each month or just maybe a few times a year
