Anyone else notice windows defender is updating 6 times every day?

I noticed something very strange today while I went to Microsoft's website while viewing defends updates. When I looked at what the update contained it said that "no threat detections have been added" why is Microsoft pushing updates with no definitions being added?

Maintenance, signature deletions, etc...
Note that Security Intelligence isn't just added signatures, it includes other stuff.

Thank you very much for the reply I guess its good that Microsoft is stepping up the game with it's updates to the product.

I've checked my update history on Windows Defender and its updating once per day according to my history.

I've checked my update history on Windows Defender and its updating once per day according to my history.

By default it checks for update once a day but they release updates multiple times in a day.

I force the updates by using Settings app , they average 4-5 per day, more or less.

If checking the official release notes, for today December the second 2019 it already updated 8 times.

Updating multiple times a day brings no advantage. You may see @Andy Ful's explanation here BAFS > definition updates

Yes i'm fully aware that most detections are detected by they're cloud based protection it's still nice to have both cloud and signatures although nothing is 100% im still very happy with WD. The best part about the program is no annoying advertisements.

When updates say "no threat detections have been added," I think it's mostly to remove false positives.
