A recent Play Store update to 4.3.10 cleaned up some rough edges and added a few minor features. Although, one of those features was contentious to say the least. The Recently Updated section of the My Apps page listed everything updated for the last week, which could be a long list for users with a lot of apps. It's not seven days anymore, though. Now it's more like three.
The Play Store now only considers apps updated in the last three days (give or take a little) to be recent.
