Is USACO Gold getting easier?

Is USACO Gold getting easier?
For the past three contests, the cutoff has been 800 points, and more people are promoting to platinum than ever, especially on the first contest.
Are the problems actually easier than the previous years, or is it just because the contestants are getting better, or both?
(I personally feel that they are getting easier, but maybe it’s just because I’m improving)

Idk.

Are there any particular problems from previous years that seem harder than this year’s?
