Of course they released new weekly XP objectives. They do that every week, and I don't think there is anything to complain about that.
The problem is the limited number of bonus tiers on the XP path. Instead of having only 5 bonus tiers, it should be unlimited such that every 12k XP would unlock a new tier.
I also know that people have been able to carry over their XP to the next season, but it seems to me like it isn't intended to be possible to do that but EA just hasn't been able to prevent it. And be it intentional or not, I don't think carrying over XP to the next season is a good solution, because it just means that we will have the same problem at the end of the next season. I think unlimited bonus tiers would be a much better solution.
