Currently we are two people working on Manalink.3.0. I am working on adding cards from old sets and some AI improvements and drool66 is trying very hard to insert new stuff for triggers and improve triggers overall. Unfortunately he has faced some big issues that he is trying to solve. As a result of this heavy development changes, a new update is not possible at the moment as what we have now in dev has a lot more issues than the update you have been playing.
When we will eventually release the update a rather big improvement for combat AI will be that the AI will defend a lot better considering what will happen in next turn by humans possible attacking creatures before AI decide with which creatures to attack and so keep blockers to defend.
