Remove list of recently updated apps in Mac App Store
Source.

If you hide an item you purchased in the Mac App Store, you won't get update notifications for it, and you won't see it on your Purchases page. If you're using Family Sharing, hidden items will also be hidden from your family members.

Hide purchases using these steps:


Open the Mac App Store.
Choose Store &gt; Sign In, then enter your Apple ID and password.
Click Purchases.
Right-click the item that you want to hide and choose Hide Purchase. A prompt will ask if you're sure that you want to hide the item.
Click the Hide Purchase button. The item will fade. The item below it, if there is one, will replace it in the list.


Unhide purchases using these steps:


Open the Mac App Store.
Choose Store &gt; Sign In, then enter your Apple ID and password, if you're not already signed in.
Choose Store > View My Account.
Enter your Apple ID password, if prompted.
From the Account Information page, click View Hidden Purchases.
