Thaer is currently at the top of Moneros subreddit with a PR to adjust Moneros difficulty adjustment algorithm to match Masari's (due to the slow recovery time following the hard fork)
According to Thaer, the rebase/refactoring has been moved up a couple weeks to mid-April. This puts Masari ahead of Aeon in terms of it's timeline (Stoffu stated that they [Aeon] are now aiming for early May)
