What do the new blue and orange symbols mean in the multiplayer lobby?

I've noticed some new additions to the UI in the multiplayer lobby since the last patch (pictured below). Instead of just showing a player's N7 rating, it sometimes cycles through two other numbers. What do they mean?

The number with a blue background indicates the number of times that you've promoted your currently selected class. It will only appear if you've promoted that class at least once.

The number with an orange background is the amount of Challenge Points you've earned. The 1.04 patch introduced a new system where players earn Challenge Points for completing milestones (such as obtaining a certain number points while using a specific weapon). Each milestone completed will award the player some Challenge points, and the sum of these points is shown next to the trophy icon. See this blog post for more information about Challenges.
