I saw the thing about starting the release process for 0.C, and I’ve been playing the game again lately, so I’ve updated RetroDays. I know there isn’t a freeze just yet, but hey.
As usual, all new tiles are accounted for (as of the experimentals a couple of days ago), but I made a few changes too. I mean, I often tweak and fix things as I go - as I play the game more and see new ways in which certain tiles are used - but there were a couple of more noticeable ones this time.
I changed windshields so that they’ll look a bit more reasonable in a vertical line, largely because they didn’t look right on things like buses and luxury RVs before - vehicles with windshields down their sides.
I also gave all (deciduous) trees seasonal variants, so now you get autumn colours and skeletal branches in winter. This was mainly prompted by the Blackjack Oak going in, as that’s definitely a deciduous tree, rather than just a non-specific “tree”.
Anyway, I’ll go see about making a PR now. 
Edit: Okay, the PR is up here.
Edit 2: KA101 merged it; thanks.
