They have 2 week cadence for releases. Meaning, 2018.10.5 was from week 10 of 2018. Next one is from week 12. There is usually 5 day delay between week N release number and when drivers start receiving the update.
So we're getting those TACC/AP upgrades in just a couple of weeks??? OMFG that's fantastic!
BTW, my previous two times using AP, one yesterday on the new software, and one a couple of weeks ago on the old, both times I headed east, away from town, on the freeway towards Coeur d'Alene to be in lighter traffic. Today I had to go to downtown Spokane (heavier freeway traffic) and AP worked like a champ.
I have not tried Lane Change in AP in the heavier traffic. Fact is, when the car is doing the driving I was happy to set the speed at just a little over the limit and stay in the middle lane at the speed of traffic without feeling the need to pass. I did use it in the lighter traffic and it works much better than it did before.
