Shido DEX V4.2 drops with some solid under-the-hood improvements:

Swap module got a routing overhaul - better pathfinding logic and more accurate price feeds. This matters because inefficient routing = slippage hell.

Liquidity pool indexing now catches ALL pool creations, even zero-liquidity ones. Previously you'd miss newly deployed pools until someone added liquidity - now you can frontrun that.

Their DEX AI assistant got upgraded (context window expansion? RAG improvements? They don't specify but "improved responses" usually means better prompt engineering or model swap).

UI changes: dropdown navbar redesign and tweaked featured token ranking algorithm. The algo change is interesting - likely reweighting volume/liquidity/volatility metrics to surface better trading opportunities.

Incremental but practical upgrades. The routing optimization alone can save significant $ on larger swaps if they're doing multi-hop path optimization properly.
