No real changes at this time.

your three main options:

there are mods that remove the mist. I don't like mods, but if you want to go that route..

you can place a VERY CHEAP TO MAKE torch that clears the fog, and with enough of them make a pretty fair sized working area but exploration still stinks.

you can man up & get what you need from this biome and never go back, or only go back to your lit base to grab a few pieces of meat or whatnot. You can troll the biome edge and pick up dead bunny from cross biome mob wars, and the bugs come to you at night anywhere, so a little mist cleared base for sap & shroom can be all you need after suffering through it for a few days. I think I was done in ML after about 1 week of 2-3 hours a day, but experiences/maps/etc vary a bit.
