Today, a blog post announcing the final Terminal Total Difficulty (TTD) value used for the Ropsten Merge was published: https://blog.ethereum.org/2022/06/03/ropsten-merge-ttd/
Node operators and stakers on Ropsten must
manually override this value on both
their execution and consensus layer clients to participate in The Merge, expected around June 8-9 next week.
